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.
