Build a STRONG robot that includes:
Bracing - can you do the drop test? (drop to carpet from 20cm)
One or two colour sensors
An ultrasonic (distance) sensor
A touch sensor to start the robot (optional)
Grippy wheels
Hidden wires so they don't catch
Optional additions:
A ramp to lift the other robot
A medium motor to lift the other robot
Extra wheels
Gears to give greater power
Decorations: Don't decorate your robot until you are sure it is working well. Make sure the decorations cannot get caught or prevent your robot doing its job!

using torque rather than speed to have a more successful SUMO-bot
Building a mechanism to flip your opponent.
Sensors and Motors
The Line Sensor helps the robot stay inside the ring (detects the black edge).
The Distance (Ultrasonic) Sensor finds the other robot.
Optional: Add a motor to flip the other robot. Will your flipper move continuously or just when it "sees" the other robot?
Motor choice for SUMO
Motor choice for SUMO
Small Angular Motor: This is a compact and powerful motor that also functions as a sensor. It is ideal for lightweight workloads and projects where space is limited.
Medium Angular Motor: This motor has a low-profile design, making it suitable for projects with limited space. It includes a built-in rotation sensor for accurate movement and control.
Large Angular Motor: This motor is built for high-power, high-torque applications. It provides accurate, controlled movement for more complex robotics projects and features an integrated rotation sensor with absolute positioning.
Torque means how strong your robot’s motors are when they turn the wheels.
If a motor has high torque, it can push harder and move heavy things, even if it moves a bit slower. If it has low torque, it can move faster, but it’s not as strong at pushing.
In Sumo, you want your robot to have enough torque to push the other robot out of the ring, so strong, steady power is more important than just going fast!
