Our latest robot is called ‘Cutus wirii’.

This is a very simple servo-driven robot that is autonomous. His computer is an Arduino.

The main chassis is plastic, cut with a dremel.

The servos are attached with a kind of aluminium clamp. He has a ball bearing at the back as a third wheel.

 

Two short-range infra-red sensors and a 9 V battery pack complete the rest of the electronics.

He is a very successful robot. His programme comes from another robot we made a while ago, with just a tiny bit of changing to the code.

One wheel turns backwards and the other forwards, when he encounters an object, which makes him turn away.

Some of our older robots are here and here.
