Participating in a local or national robot combat competition is a significant milestone for student robotics teams. It offers a platform to test engineering skills, demonstrate teamwork, and gain hands-on experience in a high-pressure environment. However, a successful competition requires more than just a well-built robot—it demands thorough preparation, attention to safety, and readiness to solve technical issues on-site.
This guide outlines essential protocols and best practices for student teams entering the dynamic world of robot combat competitions.
Pre-Competition Essentials: Safety and Organization
1. Safety in the Pit Area
The “pit” is where teams repair and fine-tune their robots between matches. While it fosters collaboration and learning, it can also pose safety risks. Power tools, soldering equipment, and Lithium Polymer (LiPo) batteries are frequently used, requiring teams to implement and follow strict safety protocols.
2. Securing Adequate Pit Space
Space is often limited, with most teams assigned only one table. Contact event organizers in advance to confirm your team’s participation and request additional space if necessary, especially for larger teams or more complex setups.
3. Using Maintenance Cradles
All robots undergoing maintenance must be placed on cradles that elevate the wheels completely off the ground. This prevents accidental movement and improves safety during repairs.
4. Efficient Packing and Tool Organization
Given the restricted space, bring only essential tools in a compact, organized toolbox that fits under your table. Prioritize versatility and efficiency in your equipment selection.
5. Food and Hydration Planning
Competitions can be long and physically demanding. Since food options may be costly or far from the pits, pack sufficient meals, snacks, and water to keep the team energized throughout the day.
6. Safe LiPo Battery Practices
LiPo battery transport and charging rules vary by event. Review competition-specific guidelines and carry certified charging bags and transport containers to ensure compliance and safety.
7. Routine Maintenance Tips
- Apply Thread Lock: Secure all bolts to prevent them from loosening during matches.
- Inspect Wheels Post-Fight: Confirm that all wheels spin freely and are undamaged.
- Monitor Component Temperatures: Check for excessive heat, which could signal internal issues.
Troubleshooting in the Pits: Common Issues and Quick Fixes
Despite best efforts, robots often face performance issues during events. Being prepared to diagnose and resolve problems on the spot is crucial.
1. Power Supply Problems
Symptoms like a weak drive or inconsistent response may stem from battery issues. Replace with a fully charged pack or use a Battery Eliminator Circuit (BEC) to stabilize voltage levels for the receiver.
2. Radio Signal Interference in the Arena
If a robot functions correctly in the pit but loses signal inside the arena, check that the receiver’s antenna is unobstructed and properly positioned to reduce interference.
3. Electrical Noise from High-Current Wires
Signal wires connected to the Electronic Speed Controllers (ESCs) can pick up interference from nearby high-current cables. Reroute signal wires away from power lines to minimize disruption.
4. Loose Connections
Vibrations from combat can loosen wires and fittings. Conduct thorough checks between matches to catch and correct any disconnections or loose fastenings.
Additional Guidelines for a Complete Competition Experience
1. Team Roles and Communication
Clearly define team roles before the event—driver, pit crew, safety officer, documentation lead, and spokesperson. This helps streamline operations during matches and improves coordination in high-stress scenarios. Use walkie-talkies or mobile messaging apps for quick team communication if permitted.
2. Documentation and Inspection Readiness
Prepare and carry all required documentation, including safety checklists, technical specifications, and compliance forms. Many competitions require pre-match inspections; being ready saves time and demonstrates professionalism.
3. Practice Under Match Conditions
If possible, simulate match scenarios before the event, including setting time limits for repairs and troubleshooting. This builds speed and confidence for handling actual competition pressure.
4. Respectful Pit Etiquette
Encourage your team to be respectful of other teams’ space and equipment. Avoid loud music or disruptive behavior and always ask permission before taking photos or closely inspecting other robots.
5. Spare Parts and Redundancy
Carry commonly used spare parts—wheels, belts, armor panels, ESCs, and even a backup receiver if possible. Redundancy can mean the difference between forfeiting a match and staying in the tournament.
6. Technical Logs and Match Notes
Maintain a simple repair log or notebook to track any technical issues, solutions applied, and performance notes after each match. This helps identify patterns and prepare for future rounds.
7. Mental and Emotional Preparedness
Competitions can be intense, especially for younger students. Encourage a healthy attitude toward wins and losses, focus on learning, and emphasize sportsmanship throughout the event.
8. Cleanup and Exit Protocol
Ensure the team leaves the pit area clean and in good condition. Organizers notice respectful behavior, and this helps build a good reputation for future participation.
