Introduction 1.1 What is the Aerospace Robotics Competition? The Aerospace Robotics Competition (ARC) is a high school drone competition offered by the non-profit organization STEM-ED INC. STEM-ED INC has the mission of providing hands-on, accessible, and relevant opportunities for students to encourage them to join STEM. This mission is accomplished through three major focus areas: ARC is currently offered in 6 regions: • Antelope Valley, CA: AntelopeValley@stemed.org • Midwest (IN): Midwest@stemed.org • New England (NH): NewEngland@stemed.org • Mid-Atlantic (VA): MidAtlantic@stemed.org • San Diego, CA: SanDiego@stemed.org • Silicon Valley, CA: SiliconValley@stemed.org • Other: Support@stemed.org Each region consists of up to 30 teams, with volunteers providing local support and events. Regions with up to 18 teams will host a Saturday-only competition. Regions with 19-30 teams will host a 2-day competition from Friday through Saturday. Event schedules will be finalized and published after registration is closed and at least 7 days prior to the event. 2026 ARC National Competition Rulebook Rev A Page 5 The top 3 champions from each region will also be invited to the ARC National Championship. The National Competition rulebook is released approximately 30 days before the event, with further details distributed throughout the season. 1.2 What are the Benefits of ARC? 1.2.1 For Students ARC seeks to ignite a passion for aerospace-related STEM work in high schools around the nation. The competition is built upon three pillars: A. Hands-on flying of unmanned aerial vehicles (UAVs) B. Developing knowledge of unmanned and autonomous systems C. Learning basic aerospace engineering principles High school students (and certain select middle school students/teams) gain valuable experience with hands-on designing, building, testing, and flying of quadcopter drones. They are encouraged to use the engineering process, complete independent research, and practice communication and teamwork skills. 1.2.2 For Volunteers STEM-ED INC is 100% volunteer-operated, which supports the mission of an affordable competition. All volunteers are passionate about promoting accessible STEM opportunities to students of all backgrounds. ARC needs a wide variety of skill sets for these events to be possible, and volunteers are encouraged to learn and grow in any topics of interest. Please contact your local region or Support@stemed.org if you are interested in receiving more information about supporting STEM-ED INC as a volunteer. 1.2.3 For Sponsors Robotics events require an extensive list of supplies, which must be purchased through team fundraising or sponsorship. As STEM-ED INC aims to provide an affordable event to all students, sponsorships are critical for reducing team participation costs and creating a fantastic competition experience. Donors can support STEM education in their community and nationwide by providing financial assistance through the registered 501(c)(3) non-profit organization STEM-ED INC. Please contact your local region or Support@stemed.org if you are interested in receiving more information about supporting STEM-ED INC as a donor. 2026 ARC National Competition Rulebook Rev A Page 6 1.3 Season Overview 1.3.1 Mission Background While drones are exciting and fun, there is a greater purpose to the skills learned through ARC. As the season progresses, challenges are focused on developing several areas of students’ lives. Engineering: • The engineering process develops vital critical thinking skills useful in all aspects of engineering and life. • Hands-on skill development improves coordination, experience, and confidence in handson projects. • Completing ARC challenges promotes creativity in designs, develops an understanding of successful structures, and boosts problem-solving abilities. • Troubleshooting skills are important for all aspects of life, promoting a logical process of patiently working through issues to find a solution. Drones: • Since drones are a growing technology with a wide variety of functions, students develop an understanding of real-world problems and solutions through getting hands-on experience with cutting edge technology. • ARC challenges are related to positive applications of drones, giving students the opportunity to ponder the humanitarian benefits of their skills. Communication: • Teamwork is required for all engineering roles, so ARC provides challenges which encourage teamwork for success. • No matter how impressive a design is, if the engineer cannot communicate properly, the design cannot be used. ARC requires both verbal and written communication, so students build these critical skills through practice. Ethics: • Ethics is central to the competition, guided by STEM-ED’s core values of Integrity, Excellence, and Respect. Volunteers and students are expected to uphold these principles throughout the event. • STEM-ED has partnered with the Saint Anselm College Center for Ethics in Society to illuminate the need for students to consider the ethical implementation of technology development. • Through humanitarian challenges, students learn to apply their skills to improving the world. • ARC prioritizes safety, urging teams to consider the well-being of others, including opponents and spectators, rather than solely focusing on winning. • Humility and admitting mistakes are vital for engineers to prevent dangerous, costly errors. ARC fosters a supportive environment in which students feel safe asking questions and seeking help. 2026 ARC National Competition Rulebook Rev A Page 7 1.3.2 Rulebook Overview We are excited to have you join us for the 2026 National Aerospace Robotics Competition!

Competition Overview 2.1 Competition Venue Each ARC competition venue will use standardized specifications for safety and field setup, which will be described further in this section. Teams must be sure to learn all safety requirements and follow volunteer instructions for a successful event. Figure 2.1 below shows the flying field boundaries. These boundaries will be marked with soccer cones (or similar items) and keep all personnel outside of the drone tether range. The red zone around the field is for the pilots and copilots of the current round only. Their teammates, coaches, mentors, and parents/guardians may spectate from the team support zone. Students and spectators from other teams not currently participating must stay outside of both zones and should watch from either the bleachers or the team pits. See Section 5.2 for details on this rule. Figure 2.1 Field Zones Team technical and ethical presentations are completed indoors. A projector will be provided, and the judging panel will display the teams’ virtually-submitted presentation slides. 2026 ARC National Competition Rulebook Rev A Page 9 2.2 Team Roles Teams comprise of students and a coach, and they may also be supported by mentors, parents/guardians, school administrators, friends, and more.

Additionally, teams must receive a 2026 National Competition Invitation from their Regional Event and RSVP within 7 days of receiving the invitation. Teams who do not RSVP within 7 days, or who decline the invitation, will forfeit their spot on the roster. The invitation will then be offered to the next eligible team from the respective region. There is no additional registration fee to attend the National Competition, but teams are responsible for their own travel expenses. 2026 ARC National Competition Rulebook Rev A Page 13 3. 2025-26 Season Challenges The 2025-26 season will include 2 flight missions, a collection of virtual tasks, a technical presentation, and an ethical presentation. See the following sections for details on each portion. During each flight mission, teams will be assigned a color: Orange or Blue. Color assignments will be included on the competition schedule, and teams will be queued by color. This assignment is randomly selected, and it is solely used for queueing and determining which color objects a team will be using. See following subsections for diagrams to clarify each task. Most rules from the Regional Competition Rulebook will be used at the National Competition. Items written in purple are updated for the National Competition. 3.1 Component Descriptions Table 3.1 below lists the components used for flight missions, along with the acronyms used to label them. See 2025-26 Field Kit Assembly Guide for a detailed guide on building an official competition field, along with recommendations for affordable alternative components for practice.

In these high-risk situations, search and rescue teams step into danger to save others. But what if technology could take their place? This competition challenges you to do exactly that. Your mission: engineer a rescue drone capable of locating and aiding survivors in treacherous waters. This drone must be fast, precise, and reliable under pressure. The stakes are real: in the field, lives depend on speed, accuracy, and innovation. Only the best designs will rise to the top. Will your team’s drone prove ready for the future of rescue operations – or sink under the challenge? Your mission is to identify a stranded swimmer, drop a lifesaver, and pull the swimmer to safety. If your team is prepared for an advanced challenge, tasks may be completed using autonomy and computer vision. Ideally, we wish to precisely lower the lifesaver to the swimmer and tow them to shore; however, teams may also consider dropping the lifesaver near the swimmer instead. This is more difficult for the swimmer to retrieve, but it is an easier task to complete. While strategizing, consider the drone’s capabilities, time and funding constraints, and your team’s coding proficiency to determine which challenges to tackle. This section will provide detailed instructions for completing this mission. 3.2.1 Tasks Your mission consists of the following tasks: 1. View swimmers (FC2): a. Take off from FC4 i. Teams may take off and fly over swimmers autonomously (most points) or semi-autonomously (fewest points). b. Use drone-mounted camera to view swimmers. c. Transmit footage to laptop computer or handheld monitor. 2. Identify swimmers (FC2R and FC2B): a. Use camera feed to determine which swimmer must be rescued first. i. Teams may visually identify the swimmer through the camera feed (fewest points), or they may use a computer vision program* to autonomously identify the swimmer (most points). ii. The swimmer in red (FC2R) is a child and is to be rescued first. The swimmer in blue (FC2B) is an adult and is to be rescued second. 3. Drop lifesaver (P1) to swimmer in red (FC2R): a. P1 is preloaded before the match. b. P1 may be delivered by being: i. Dropped/lowered into FC1 on a line (most points). 2026 ARC National Competition Rulebook Rev A Page 15 1. Note: This task is a prerequisite for completing Tasks 4 through 6. 2. Teams may use any line. No line will be provided at the competition. ii. Dropped freely into FC1 without a line. iii. Dropped within ten feet of FC1 (fewest points). 4. Pull red swimmer (FC2R) to safety (outside of FC1): a. Hook P1 around FC2R. b. Drag FC2R to any location outside of FC1. 5. Drop lifesaver (P1) to swimmer in blue (FC2 B): a. Teams must rescue the swimmer in red (FC2 R) before rescuing the swimmer in blue (FC2B). b. P1 may continue to hang from the line while flying from the red swimmer to the blue swimmer. The line does not need to be spooled back into its starting position. 6. Pull blue swimmer (FC2B) to safety (outside of FC1): a. Hook P1 around FC2B. b. Drag FC2B to any location outside of FC1. 7. End round on landing pad (FC4): a. Touching any part of FC4 will be considered successfully landing on it. Each of the above tasks may be completed autonomously or semi-autonomously. Teams may choose to complete some tasks semi-autonomously and some autonomously. For example, a team may choose to take off and fly over the targets semi-autonomously, then prompt the drone to autonomously run a computer vision program and drop the lifesaver, then finally regain semiautonomous control to rescue the swimmer and land. The pilot/copilot should communicate with the Flight Judge throughout the round to announce and demonstrate when a task is being performed autonomously. In the event of poor weather conditions, Competition Coordinators may choose to hold one or more flight rounds indoors. For indoor flights, teams MUST perform takeoff and landing semiautonomously. The remaining tasks may still be completed autonomously or semi-autonomously. *Note: if the competition field has red markings (such as a school logo), ARC volunteers will do everything possible to ensure these markings are not within the field boundaries. However, these markings may be visible outside of the field boundaries, so please keep this in mind when preparing computer vision programs. 3.2.2 Mission Schedule Each round of Mission 1 will be 10 minutes. The Field Manager shall count down from three to begin the round. This countdown will begin when the team has attached the tether, connected the battery, armed the drone, and stepped back into the Red Zone. Any other piloting tasks, including connecting computers/monitors and starting autonomous programs, will be counted in the allotted 10 minutes. 2026 ARC National Competition Rulebook Rev A Page 16 Once the timer has begun, the pilot and copilot may re-enter the field as needed for problemsolving. Once the drone has left the landing pad, no one may enter the field for the remainder of the round. The round will continue until time is called, all possible points are scored, or the team has decided to forfeit the remainder of their time. Teams will be scheduled to complete at least one, and up to three, rounds of Mission 1. All teams at the event will be scheduled to complete the same number of rounds. If multiple rounds of Mission 1 take place, teams will be given a final score equal to the maximum of all round scores. 3.2.3 Field Layout The following figures provide field diagrams. See Figure 3.1 for the placement of each item on the field. See Figure 3.2 for measurements of item placement (figure not to scale). Notes: • Many items have approximate location callouts, indicating variability in field setups. • “Random Placement” items will be located in the same half of the field shown in field diagrams, but no measurements are indicated. • Teams are advised to practice using various configurations to prepare for all possibilities. 2026 ARC National Competition Rulebook Rev A Page 17 Figure 3.1 Mission 1 Field Layout 2026 ARC National Competition Rulebook Rev A Page 18 Figure 3.2 Mission 1 Field Measurements 2026 ARC National Competition Rulebook Rev A Page 19 3.3 Mission 2: Savior of the Seas Across the world, thousands of sea turtles wash ashore, stranded and vulnerable, while whale populations migrate vast distances without researchers able to follow their every move. Conservationists work tirelessly to respond, but the ocean is vast, and their reach is limited. What if advanced drone technology could extend their efforts to rescue and monitor our sea creatures? Your challenge is to engineer a marine rescue and research drone system capable of performing two critical tasks: assisting stranded turtles and safely tagging whales for migration studies. Drones must carefully lift each stranded turtle and place it into the ocean. They must also use a camera to identify whales and tag the correct species. This is more than just a drone mission – it is a chance to demonstrate ethical engineering in action by collaborating with another conservationist group. Teams will work together to tag whales, while also being allowed to recover stranded turtles from the opposing side of the field to ensure that no animal is left behind. This section will provide detailed instructions for completing this mission. 3.3.1 Tasks Your mission consists of the following tasks: 1. Rescue stranded turtles (P2): a. Lift P2 and deliver into FC1. b. Each side of the field (orange and blue) will have ten turtles (P2) to rescue. Teams may rescue turtles from the opposing side of the field IF they have successfully rescued all ten from their assigned side. i. Teams MAY NOT attempt to interact with the opponent’s turtles until they have rescued all ten of their assigned turtles. ii. Teams MUST yield to their opponent when flying on the opponent’s side of the field. For example, if the blue team has scored all ten of their turtles, they may begin to score turtles from the orange team’s side of the field. However, if both teams are attempting to pick up the same turtle, the blue team MUST yield and allow the orange team to rescue their own turtle. iii. Teams are expected to remain sportsmanlike at all times, and Field Managers may give penalties for conduct that may reasonably be deemed unsportsmanlike, including guarding turtles to prevent the opponent from collecting them. c. The first turtle (P2) rescued from the opposing side will earn a point bonus. This will be awarded for the first team to score all ten of their own turtles and one of their opponent’s. 2. Tag whales (FC3): a. Carry P3. i. Teams may use a mechanism to lift tags from the ground, or they may preload one or more tags onto their drone before beginning the match. 2026 ARC National Competition Rulebook Rev A Page 20 ii. Any tags that are not preloaded will be placed on the ground approximately five feet in front of the landing pad. b. Use a camera to identify each species of FC3. i. The field will contain three species of whales: Blue (FC3B), White (FC3W), and Purple (FC3P). Each side of the field will have two of each FC3 B and FC3W, and the teams will share one FC3P placed along the centerline of the field. c. Place P3 onto 2x FC3B and 1x FC3P. i. If both teams on the field place P3 onto FC3P, each team will be awarded an additional score for collaboration. ii. Instead of placing a tag, teams may choose to land on 2x FC3B and 1x FC3P for fewer points. d. Avoid interfering with FC3W. i. A penalty will be awarded for landing on FC3W. ii. A penalty will be awarded for dropping a whale tag on FC3W. 3. End round on landing pad (FC4): a. Touching any part of FC4 will be considered successfully landing on it. 3.3.2 Mission Schedule Each round of Mission 2 will be 7 minutes. The Field Manager shall count down from three to begin the round. This countdown will begin when the team has attached the tether, connected the battery, armed the drone, and stepped back into the Red Zone. Teams will be scheduled to complete at least one, and up to three, rounds of Mission 2. All teams at the event will be scheduled to complete the same number of rounds. If multiple rounds of Mission 2 take place, teams will be given a final score equal to the maximum of all round scores. 3.3.3 Field Layout The following figures provide field diagrams. See Figure 3.3 for the placement of each item on the field. See Figure 3.4 for measurements of item placement (figure not to scale). Note that both drones will be piloted from the same side of the field. Any attempt to interfere with an opponent’s operations will result in immediate disqualification from both Missions 1 and 2. Notes: • Many items have approximate location callouts, indicating variability in field setups. • “Random Placement” items will be located in the same half of the field shown in field diagrams, but no measurements are indicated. • Teams are advised to practice using various configurations to prepare for all possibilities. 2026 ARC National Competition Rulebook Rev A Page 21 Figure 3.3 Mission 2 Field Layout 2026 ARC National Competition Rulebook Rev A Page 22 Figure 3.4 Mission 2 Field Measurements 2026 ARC National Competition Rulebook Rev A Page 23 3.4 Flight Procedure Flight portions of the competition will follow the process below (see Figure 3.5 for location references). Please note that the Field Manager will be directing all major steps, and teams must wait for his/her instruction before completing these steps. The Field Manager is also responsible for safety and final rulings. Teams are expected to obey Field Manager directions, including to activate the Kill Switch immediately when commanded. Teams must arrive at the Queueing Table at least 5 minutes before their round is scheduled to begin. Teams who do not arrive to their round during their allotted time slot will forfeit their match and will not be given an opportunity to complete it at a later time.

Cleanup: • Team gathers belongings and exits • Next team begins setup 3.6 Ethical Presentation Drones are powerful devices with seemingly limitless applications, ranging from environmental monitoring and disaster relief to agriculture and national security. However, with such potential comes an equally great responsibility. A critical aspect of engineering is not only designing advanced technologies but also carefully determining their ethical uses. Engineers possess the skills and creativity to develop innovations that can transform the world for the better, but doing so requires more than technical expertise alone. It demands a thoughtful and heartfelt commitment to engineering ethics—an awareness of how each design choice, application, and deployment impacts people, societies, and the environment. By grounding their work in ethical responsibility, engineers ensure that technology remains a tool for positive progress rather than unintended harm. STEM-ED INC is challenging YOU to consider how to use your developing skills for the betterment of our world. 3.6.1 Grading See Appendix A for the Ethical Presentation Rubric. See Section 3.7.2 to further understand the process of this presentation. Note that some points are open to interpretation, and teams are encouraged to be creative in their responses. 1. Academic Validity: • Explanation of theory/doctrine: o Present proposed solution to ethical dilemma o Discuss theory/doctrine behind this decision • Programming the drone: o Describe programming to achieve the proposed solution 2. Comprehension and Elocution: • Comprehension: o Demonstrate clear understanding of the problem and why engineering ethics would be critical in this situation 2026 ARC National Competition Rulebook Rev A Page 28 • Elocution: o Deliver information in a comprehendible and professional manner 3. Discussion: • All speak and demonstrate inclusion • Students demonstrate respect during disagreements • Students value one another’s ideas* • Note: teams will not be graded on the content of this discussion, only the collaborative efforts. Thus, students should feel free to communicate and not fear suggesting “wrong” answers during this discussion. 4. Q&A Responses: • Team professionally answers all questions from judges *Note an important concept for students to learn: in engineering, the best way to come together and select the best solution is by viewing everyone as a cohesive unit. Do not focus on “my idea,” but instead seek “our progress” in discussions. 3.6.2 Process Teams will be put into a similar setting as the Technical Presentation; however, this presentation will involve answering an ethical dilemma posed by the judges. Teams will be given time to prepare a response, then they will present this response to the judges. As in the Technical Presentation, presentations should be given entirely by students without the assistance of coaches, mentors, or parents/guardians. 1. Setup: • Team enters room and stands in designated area • It is highly recommended that teams bring paper and writing utensils to assist in the discussion portion. If available, judges will provide a whiteboard, but this will vary by venue and should not be expected. 2. Question: • Judges provide ethical dilemma to team 3. Discussion: • Students may discuss this question together for up to five minutes • This discussion will take place in front of judges, but it will only affect the discussion portion of their grading on the rubric 4. Presentation: • Students may present for up to five minutes 2026 ARC National Competition Rulebook Rev A Page 29 • Students should answer the ethical dilemma in a manner that fulfills the grading requirements o Note that some requirements are open-ended to encourage creativity 5. Q&A: • Judges ask relevant questions to students for up to 5 minutes • Students answer questions as they deem fit 6. Cleanup: • Team gathers belongings and exits • Next team begins setup Students may not discuss the ethical question with other teams until all teams have completed their Ethical Presentation. 2026 ARC National Competition Rulebook Rev A Page 30 3.7 Scoring Equations 3.7.1 Possible Scores The following tables provide the maximum possible scores for each task.

The UAV will be inspected at the competition prior to flight (see Appendix B: Technical Inspection Rubric). All components must also remain within the budget allowances shown in Table 4.1. Teams will be required to present their list of components and prices during the technical inspection. Note that components/kits suggested by STEM-ED INC will meet all financial requirements. See Section 4.1.6 for component recommendations. All designing, building, coding, and testing is to be completed by students only. Teams may request guidance from adult coaches and mentors, but all hands-on work and major decisions should be completed by students only. Drones MUST have a kill switch to immediately cut the drone’s motors in case of emergency. Please visit https://www.youtube.com/@aerospaceroboticscomp501c3 for assistance if needed. 4.1.1 Structure Teams must create a drone structure that fits within size and component limitations: • • • • • The overall UAV dimensions must not exceed 36 inches by 36 inches by 36 inches when placed on the ground with no propellers attached (the drone should be able to fit in a box that is a 36-inch cube). The UAV must have 4 motors with 1 propeller each. These propellers may not exceed 14 inches in diameter. The UAV must not have any lifting surfaces other than these propellers. The UAV must have a carabiner clip securely fastened within the tether zone (see Figure 4.2). This carabiner must be connected to the field tether carabiner before the drone may be powered on. The structure must be sturdy, as judged by the Technical Inspector. Components may not be loose. The drone must stand on legs. The legs must extend at least 4 inches below the electronics or drone structure closest to the ground. The legs must extend no greater than 10 inches below the drone base plate. See Figure 4.3. 4.1.2 Mechanism Design Teams must create a unique mechanism that meets size and structural integrity requirements: • Teams must design and build a unique mechanism to complete the flight tasks. Teams may not use a Commercial Off The Shelf (COTS) mechanism, such as a pre-made claw. 2026 ARC National Competition Rulebook Rev A Page 34 • • • • • The mechanism may be controlled with multiple servos, but all servos are to be powered by one single NiMH battery (see Section 4.1.4). The mechanism must begin within the mechanism allowable zone seen in Figure 4.2. The mechanism may not extend above the drone base plate at any time. The mechanism may not detach from the drone at any time during flight. The mechanism must not extend beyond the mechanism allowable zone seen in Figure 4.3. Teams may use different mechanisms for different competition events, but all mechanisms must pass technical inspection to be used (see Appendix B: Technical Inspection Rubric). 4.1.3 Controls Teams must use the required electronics to control their drones: • • • • Teams must have a GPS sensor securely mounted onto the UAV. Teams must use one of the following flight controllers: o The Cube Orange+ o Pixhawk (any version) Sensors: o Teams may use the accelerometer, gyroscope, magnetometer, and barometer contained within the flight controller. o Teams may not purchase/use any additional sensors. o Teams may add an approved camera (see Section 4.1.6) to transmit live footage to their ground station. For teams choosing to use computer vision, a Raspberry Pi companion computer (any version) may be used. 4.1.4 Batteries Teams must use batteries that fit the following specifications (see Section 4.1.6 for recommendations): • • • Main UAV Battery: o Teams must use a lithium polymer (LiPo) battery to power the flight controller. o The battery cannot have more than 6 cells. o Teams must use commercially available batteries. Homemade batteries are not allowed. o Teams must use proper battery usage/storage techniques – see Section 4.2. o Teams may not use any batteries displaying signs of damage, including dents, cracks, swelling, and smoking. Servo Battery: o Teams must use a nickel-metal hydride (NiMH) battery to power the mechanism servo/actuator. Safety: o Battery wires MUST be securely restrained away from propellers, servos, and the ground. 2026 ARC National Competition Rulebook Rev A Page 35 Figure 4.1 Drone Electronics Zones Figure 4.2 Drone Mechanism and Tether Mount Zones 2026 ARC National Competition Rulebook Rev A Page 36 Figure 4.3 Drone Mechanism Extension Zone, Vertical 2026 ARC National Competition Rulebook Rev A Page 37 Figure 4.4 Drone Mechanism Extension Zone, Horizontal 2026 ARC National Competition Rulebook Rev A Page 38 4.1.5 Budget Requirements Teams may not exceed the budget requirements listed in Table 4.1 – this is a requirement for participating in the competition. Teams must provide a spreadsheet of all used items and associated costs (commonly known as a Bill of Materials, or BOM, in industry). Teams may list the actual purchase price for each item if it differs from the retail price. Table 4.1 Budget Requirements Item Max. $ Drone $3,000 Notes • • • • • • Includes: Flight controller Motor controllers Motors Propellers LiPo Batteries All spare components brought to competition • • • Includes: Structural components and hardware Servo and gears NiMH Battery Mechanism $300 Transmitter/Receiver $300 See recommended below. Sensors $0 No additional sensors may be purchased. Tether Supplies - Required carabiner Camera - Camera Feed Monitor - May use any for practice, but may only use required models at competition (see also Section 4.1.6). • Camera: Link • Camera Feed Monitor: Link Total $3,600 Does not include required carabiner, camera, and camera feed monitor. Note: teams using materials procured 1 or more seasons ago may reduce the cost of the respective item by 20%. For example, if a team purchased a drone for $500 during the 2024-25 season, they may list it on the budget as $400. This accounts for the potential need to purchase replacements for aging components. 2026 ARC National Competition Rulebook Rev A Page 39 4.1.6 Supplies and Sources The following options are recommended as acceptable and compatible components for teams to use. Note that STEM-ED INC is not sponsored by nor endorses any of the recommended suppliers, and teams are not required to purchase through the provided links. Required Components • Carabiner: Any strong carabiner with a properly-functioning latch to link with tether carabiner. • Camera Mount: o If using the ARC-provided RunCam camera, drones must have quick attachment method that does not damage the camera or its antenna. Teams may purchase a camera and monitor for practice (see links below), but teams may not bring them to the competition, as they may cause signal interference. ▪ Camera: RunCam Spotter V2 FPV Camera and 5.8GHz Transmitter (Link). ▪ Monitor: RunCam 5.8GHz 4.3” FPV Display Screen (Link). o If using the Arducam Camera for Raspberry Pi (Mission 1 only), drones do not need to have a quick attachment method, and teams should bring their own camera to the competition. These cameras will not be supplied by ARC. Recommended Drone Kits • Option 1: ARC-Recommended Drone Kit o See spreadsheet of components: https://www.stemed.org/recommendedsupplies • Option 2: DEXI PX4 Development Kit (Link). Note that this drone kit will require the addition of team-designed legs. • Option 3: 2024-25 ARC Season Kit Drone o This kit is no longer available, but returning teams may use this kit if previously purchased. o See DRONE KIT LINK for recommended upgrade components. • Option 4: Student-designed drone. o Teams may compete with any drone that meets all requirements within this rulebook. Teams are welcome to design a drone instead of using the above suggested kits.

Banned Components The following components may not be brought to the competition venue, as they would cause signal interference which may lead to drone malfunctions. This requirement is for both safety and sportsmanship and will be strictly enforced (see Section 5.2). • Teams may not bring the RunCam Camera and Monitor set to the competition venue (see “Required Components” above). • Teams may not bring/use any device which may interfere with opponents’ telemetry signal. 4.2 Safety and Legal Requirements STEM-ED INC will be releasing official guidelines for safety policies and adherence with FAA requirements. This document will include additional rules and will be considered an addendum to the 2025-26 ARC Regional Competition Rulebook. Additionally, all pilots are expected to be able to perform their duties in a safe manner. If a pilot is unable to safely operate the drone for any reason, including but not limited to a medical emergency, he/she will be asked to land the drone and to allow a teammate to pilot during future rounds. As previously mentioned, teams MUST follow the commands of the Field Manager, including where to stand and when to activate the Kill Switch. For any safety and legal questions, please visit https://www.faa.gov/ and/or contact Support@stemed.org for assistance. 2026 ARC National Competition Rulebook Rev A Page 41 5. Competition Rules 5.1 Logistics Upon arrival at the competition venue, teams must first report to the check-in table where volunteers will distribute items such as wristbands, schedules, and maps. Teams will then be directed to their pits, which will be their “home base” throughout the event. Teams will be able to keep all items at their pit table and charge batteries at a nearby battery charging station. Once flying matches begin, teams must follow the routes as seen in Figure 5.1. Teams are expected to be at the queueing table on their respective side of the field during the match before their assigned time slot. Queueing volunteers will guide teams from the queueing table to the ground station table once their assigned time slot begins. Teams who are not competing in the current match may not enter any field zones at any time. Students who are not the pilot or copilot, along with coaches, mentors, and parents/guardians, may not enter the red zone at any time. These rules are critical for safety, so all team members and spectators are expected to follow volunteer instructions and to exit areas immediately upon request. Figure 5.1 Flight Round Routes 2026 ARC National Competition Rulebook Rev A Page 42 5.2 Conduct Requirements If teams believe they received an incorrect ruling during their flight round, they are welcome to discuss the issue with the Field Manager, who will be happy to correct any errors as needed. Ruling challenges may be made by student team members only, not parents/guardians, coaches, mentors, or spectators, and should remain cordial. Teams are expected to adhere to safety rules at all times, including obeying field boundaries, keeping electronics powered off at all times off-field, completing a reinspection after a drone is damaged, and using the tether at all times on the field. Volunteers will provide guidance and reminders, but continued willful non-compliance will result in a discretionary penalty. See Table 5.1 below for potential penalties, the distribution and value of which will be determined by the Field Manager and/or respective Regional Coordinator. These rules are in place to ensure the competition is safe and enjoyable for all. Teams attempting to follow rules and remain sportsmanlike will not need to worry about receiving these penalties.
