Project: SpinBalance – Introduction

I don’t have a good track record with mechanical projects – anything that moves. I do much better with purely electrical devices. As soon as you have moving parts you have to deal with things like friction, backlash, wear, tolerances, inductive spikes… I don’t like any of those things. Every couple of years I forget this and think it’ll be different this time, so here is another mechanical project.

A couple of years ago while still at university I started a balancing robot project. I quickly gave up. The reason was that my robot was free standing and balanced on two wheels. There were a number of issues:

  1. The robot would run around and I didn’t have enough space of my desk to allow it to balance
  2. The programming cable would restrain the robot so I also had to unplug my programming cable each time I wanted to test it – not ideal for quick iteration
  3. It was hard to control the environment and get the motors aligned
  4. The robot could not have an external power source so had to rely on batteries

This time I am still going for a balancing robot but I am going for a rotational robot, rather than a free standing robot.
