A competition-style mini sumo build with low wedge, high-traction tires, line sensors, opponent detection and fast but controlled pushing.
A sumo robot is a compact competition robot that wins by sensing the ring edge, finding the opponent and pushing without driving out. It is a useful build because every design choice shows up quickly in matches.
Focus first on traction, low center of gravity and reliable edge detection. A simple robot with strong wheels and clean sensor logic beats a complex robot that reacts late or browns out.
Gets under opponents and keeps weight low
Strong pushing force
Traction on the ring surface
Detects the white edge line
IR, ToF or ultrasonic detection
High current bursts without brownout
Two motors, front wedge, edge sensors and a simple search pattern.
Add front ToF sensors and aggressive ramped acceleration.
Use wider sensing and safer ring-edge behavior.
Treat the generated output as a prototype plan, not a certified product. Body-adjacent, high-voltage, optical-energy and mobility builds need qualified review before real-world use.
Torque and traction first. Speed only helps if the robot still detects the edge reliably.
Put line sensors near the front corners and test edge reactions at full battery voltage.
No. Sumo strategy is mostly fast sensing, motor control and mechanical grip.
