4B Robot

First Test

This is 4B's first test with an on-board battery. In this video, I tested how it opens and closes into a ball, the walking algorithm and also a very rough open-loop rolling algorithm.

Build

This is the build video of 4B, a robot I started working on last year but had to stop because of the other projects that I had. This robot has 4-legs with a total of 12DOF, and what's special about it is that it can fold in a 6cm diameter ball!

The full test video is coming next week :)

4B Issues

In this video I tried to explain all the issues I have encountered while building my 4B transformer robot.
