A project log for Dogbot

A quadrupedal walking robot

We've been trying some simple gaits animations to prove the robot can walk independently.  These run through a fixed set of movements without any feedback, this is the first one that worked so there is a huge room for improvement.  It falls over in the end of the video because of a problem with one of the motor controllers, it shouldn't take too long to track down and sort out.

That doesn't look too good. Is it power problems?

We had it walking for about 5 minutes before the video. At the end one of the motor controllers cut out, I am adding more diagnostics to work out why.

The legs have some give in them, which wasn't accounted for properly the first time it was walking. With a bit of tuning it will be much better.

Oh, I see, I wasn't sure if it's the legs or the motors. This is good news, because in the worst case you can just make the legs more rigid.
