Rhythm bug

After my post on subconscious tapping a while ago i have been pondering over my own version. I have been developing a very simple robot that bounces back and forth between two objects; the further apart the objects the slower the beat. I plan to make quite a few of these little bots so that different beats can be made by having each robot bounce between different distances.  Here’s a quick mock up of how the robots will be made –

I have nick named him Gaz the destroyer i made a mock up out of cardboard before this one who was not quite so successful. He was called Baz the racing slug! i do in fact need to get out more.

I am quite happy with the over all performance of the mock up. There are a few things to take into consideration. The robot produces a slight wheel spin on the return journey. This is because of bad weight distribution. I have decided to counteract this by making the robot 4 wheel drive. I also want to consider what material to construct the mechanism with so that when the robot bashes against an object it makes a good noise.
