Cardboard Battle Bots for Creative Young Engineers
Desert Bot League brings the thrill of BattleBots to a safe, kid-friendly format where creativity, teamwork, and smart design win the day. Students build lightweight robots—primarily from cardboard and foam—then pilot them using manual, R/C, or Arduino control inside a dedicated arena. Matches are short, energetic, and referee-judged for control, aggression, and effective design, with safety and sportsmanship at the core of every bout.
Who It’s For
Grades 4–8, with teams of four students working under the guidance of a mentor. Parents can mentor one team; teachers or youth-program professionals may mentor multiple teams. Teams compete in age groupings, and members must be within two years of each other to keep play fair and fun.
What Students Do
- Design & Build: Plan, prototype, and assemble a bot using approved lightweight materials and components.
- Learn Electronics & Control: Explore motion, gearing, and control systems (manual/R-C/Arduino).
- Test & Iterate: Practice in the arena, refine strategies, and tune for reliability.
- Compete Safely: Enter best-of-three, 90-second rounds with clear rules for immobilization, force-outs, and referee decisions.
Safety First
Before any match, each robot passes a Battle-Ready Inspection for components, construction, size (fits a 10″×10″×10″ cube), weight (under 5 lbs), and compliance with control and weapons rules. Referees may disqualify any robot that risks participant or spectator safety. Weapons cannot project or discharge; metal weapons are not allowed.
Gear & Build Standards (At a Glance)
- Control: 2.4G R/C systems only (no Bluetooth or IP); hard-wired hand controllers allowed.
- Logic (Optional): One Arduino (Uno/Mega/Nano) permitted.
- Power: Single battery, max 7.4V / 1000mAh (default 4×AA).
- Drive/Actuation: Up to four motors/servos within listed specs.
- Materials: Cardboard/foam boards (max thickness specified), glue limits, select 3D prints (≤5 parts, ≤1.5″ each) or foam/EVA clay equivalents; no wood/metal/plastic armor.
- Mobility: Approved wheels/casters; no metal treads.
All components must be used for their intended function—not as armor or ballast. Full specs are provided in the team packet.
Accessibility & Eligibility
AV S.T.E.A.M. Leagues aims to remove financial barriers for lower-income and underserved communities through grants and sponsorships.
- Schools/Youth Orgs: May request up to two kits at no cost. Participate in an official Challenge Event to keep them, and earn two additional kits with each new event you enter.
- Families: May request one kit per student with a temporary credit-card hold equal to kit value; compete in the event and it’s free. If not competing, return the kit within seven days to avoid being charged.
Equipment & Materials
We encourage teams to source their own approved materials and electronics—it builds ownership, budgeting skills, and creative problem-solving. If purchasing is a hurdle, mentors may borrow a League loaner kit for the season with a refundable security deposit. Return the kit in working order after your event to have the deposit released, or apply it toward future participation. Our aim is to keep doors open for every student—please reach out if you need support, and we’ll do our best to help.
Team Format
Four students per team is ideal (3–5 allowed), with one dedicated mentor providing guidance and ensuring safety. Teams practice, test, and document their designs, then step into the arena ready to adapt and learn—win or learn, never lose.
What They’ll Learn
- Engineering Mindset: Decompose problems, prototype quickly, and iterate.
- Electronics & Coding: Power, polarity, motor control, optional Arduino logic.
- Design for Constraints: Size/weight limits, material choices, reliability.
- Team Skills: Roles, communication, gracious professionalism, and match strategy.
Season Flow
- Form a team and mentor. 2) Review the build rules and part list. 3) Prototype and test. 4) Pass inspection. 5) Compete in the arena. 6) Reflect and improve for the next event.
