Self Balancing Robot – V4

It’s been almost 4 years since I started playing with self balancing robots posting about the very first version, then the 2nd really unsuccessful one and finally a really jittery / impossible to control 3rd version…

Now it’s finally time to show you something that actually works !

Same as the previous post, this is an old project that still doesn’t work properly, but will probably never have the time to fix, so I’ve decided to post the details here, in case I need to refer to them later.

This is a quick post to dump some pictures and lessons learneth the hard way, when I tried to build a nicer / better self balancing robot.

All this dates back from October 2014, so more than 1 year ago, but I finally gave up on trying to make this work and wanted to keep all this info/details for my own reference.

Quick post about some intermediary work I had to do while working on my new Self Balancing robot.

Once the basics were done and the robot was balancing, I realised that it seemed unstable as it wasn’t staying in place…

The easiest way to deal with this would be an optical encoder for the wheels, that would tell me how much each moves.

It’s really been a very long time since I added this on my todo list, and in the past couple of week-ends I finally found the time to do it.
