Shorter Legs--New Walk Attempt

A project log for Mike's Robot Dog

Boston Dynamics' robot dog, Spot Mini is unavailable at any price. A Chinese copy is $30,000. Cut 99% of the cost and build one at home.

I decreased the length of the legs to reduce stress on the printed parts while allowing the motors to work more reliably.

I see considerable progress!

One more thing that could work is using rubber bands to take away some of that gravity force the servos have to struggle against — so that instead of being under 100% or 0% load, they would be at 50% load all the time.
