I’m glad you like the Wall-E design! For me the servos jump suddenly when starting the robot up, but work smoothly after that. The velocity controller in my sketch should help prevent sudden movements, provided that the actual servo position is where the sketch expects it to be. I’m hoping to publish a servo motor calibration guide for the Wall-E soon (in 1-2 weeks; I’m just waiting for some parts I ordered to arrive first), so maybe that will help with your issue.

It is a very good size and was well engineered for fit and strength. My electronics is slightly different as I am using an Arduino Uno with a Bluetooth shield and a robot (CMDR) shield. No need for separate batteries or power converters. I have no raspberry yet. However, when a command is sent to the Arduino from my pad, the servos jump violently. So I had to use disconnect on all the servos and motors till I can figure it out. (I may yet need separate power supplies.) I have posted some pics of Wall_e on my Facebook page. Thank you for your work on the little guy.
