Robots I have built:

Next, Quadrobot a 4 legged walking radio controlled robot that made it onto British TV in Techno Games filmed in December 2002 and shown on TV in March 2003

This fully articulated robot used 8 servos driven in programmed sequences by a PIC 16F877 micro and a further servo for bending the body to steer it.

It had a speed control with stand, walk and run modes, and all movements followed the leg actions of a small dog.

The Radio control receiver simply fed signals into the PIC micro to tell it to speed up or slow down or to turn right or left.

Unfortuntaley , while it was very stylish it was not very fast and it got beaten in the heats by a cow and a penguin!!!
