A busy day working on the robot! All the parts are printed and assembled. Now it is in the tuning, adjustments, and fixes. and TESTING!

Part of the mystery around why Mojo2 is walking backwards would have to do with the balance of the robot. In the below picture you can see the positions of the 4 "paws" and legs in comparison to the frame of the robot. Clearly, the support are well behind the center of gravity. Thus the need for my hand to provide additional tipping support.

This may be combined with the gait itself, that is very quick to move the legs to the forward position. This quick motion seems to be have a greater effect on the over all motion vs. the regular step that is at 1/2 of the speed. It would also be important to consider the amount of ground contact by the feet.
