Lego Die-Rolling Robot

Just what you need to speed up your D&D sessions!

The mission: To make an absurdly overcomplicated robot to do something as simple as roll some dice. It’s sort of a Rube Goldberg machine although for the sake of practicality there’s buttons to control the throwing and then the picking back up again so that it can be done on demand.

It uses Lego Mindstorms NXT stuff, along with some Lego pneumatics, some nifty servos, a pressure sensor and an IR transmitter from Mindsensors, along with some technic “Power Functions” motors for grinding the compressor and the conveyor belt.
