In this third model I have added sensors to trigger things such as the claw. When you touch the touch sensor the claw lifts after one second. The ultrasound detector makes the car move faster after it senses the opponent is within 10cm. Another feature is the compound gearing which allows the robot to have more power but less speed.
In this second model after a revamp I constructed a claw type mechanism that lifted the opponent after it was triggered. But so far there are no sensors or external ways to trigger it.
This first model was a skeleton of what was to be a robot with very little power. But afterwards one of the motors died (it wasn’t able to turn) so I had to start from scratch.
