Lego mindstorm ev3 sumo bot
It has a back bumper for aligning straightening the robot by bumping into walls and objects and a third large motor for attachments. There are a few variations on the build available on this site. Brian Wheeler, Hoosier Girlz. This robot is a good starter robot. The sensors in front act as a bumper. Bayou Bot - EV3 Build. This is a robot that has a strong outer frame with shielded color sensors.
It uses two color sensors, an ultrasonic and a gyro. It uses large motorcycle wheels and a ball wheel. This robot has been physically built by the designer. This robot is made with parts in the EV3 home edition only. It has a basic system for attaching motorized and passive attachments. Optimal Prime - EV3 Build. This is a quick-build robot that uses only 37 pieces including motors, sensors and wires. It features the gyro, touch and color sensors. This is a base robot similar to the one available in the Educational EV3 set , but constructed with parts available in the NXT set.

We had our candidate! Time to train him up. The original SmartBot was gradually stripped of sensors and stuff and became DummyBot — our training dummy.
Not just once, but repeatedly. So we went through a bunch of cycles of integration testing and tweaking the hardware and software. We kept failing over and over often in funny ways , but every iteration we got a bit closer to winning. One interesting thing happened along the way.
We noticed on the youtube clips that many robots tried to lift and topple their enemies. So Dave built a pretty elaborate construction for that, and I helped write the code to control the lifter. In theory it was awesome, in practice it was useless. We wanted to keep Robit simple and focused on one thing — putting up a proper fight!
We figured that would help us get under the wheels and push or topple the opponent. Any other conditions under which the referee judges that no winner can be decided. In case of a rematch, maintenance of competing robots is prohibited, and the robots must be immediately placed in the designated starting position. The only exception to this rule is if the cause of the rematch is a robot breaking.
If neither of the competing robots win, or lose, after a rematch, the referee may reposition both robots to a specified location and restart. If that does not yield a winner, the match may continue at any location decided by the referee, until the time limit is reached. All decisions by the referee are final.
