Rock and roll

I made the machine in the video below for no other reason than that I felt like making a vehicle that was propelled in a non-standard way. The idea arose when I wondered about setting my Product Design Engineering students the challenge of making a vehicle that wasn’t driven through its wheels. In the end we did a different project, but I still couldn’t resist having a go myself.

The vehicle is mainly made of corrugated cardboard with other odd bits and pieces. It’s driven by two servos controlled by an Arduino microcontroller board.

Originally there was going to be a separate weight that was shifted back and forth to make the vehicle tip. I was rather pleased when I realised that I could make the batteries, the Arduino, and one of the motors do double duty as the weight.

(I didn’t choose the carpet.)
