First Stand

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.

On February 27, the first attempt at standing was made. A couple of the joints couldn't take full speed movement--we learn by trying!

To attempt the first standing test, I needed to determine the servo angles for each motor. Below is the schematic for the system.

With the mechanism suspended, I determined the servo angles for each servo.

The numbers I retrieved are:

I applied those in an Arduino sketch (found in  files on this project).

Two joints couldn't take the stress (I went full speed on the servos, kind of a worst case situation).

I'll have to redesign and install joints--then full torque ahead!
