PIE 2 0 Self-Propulsion Video 1 of 4

The PIE 2.0 is self-propelling! I re-phased the wheels and put it on a set of steel ball bearing wheels. The floor I'm running it on is not perfect, it likes to get stuck where there are years of grime that needs to be steam cleaned off the floor, and also gets stopped climbing onto the next floor section as it is slightly higher and the PIE rolls back between pulses. There are 4 videos that I am posting here.
