Servo wheel for mobile robots

A wheel for building mobile robots. This wheel has been designed for the Futaba 3003 or compatible servo, but it can be change to other servos easily. It has been created with openscad.

For building mobile robots, the servos should be tricked so that they can turn freely.

We are using these wheels for our educational open-source Robot: Skybot
