High speed and moderate torque is good as we want to make it stable, not to stand the robot up from laying position. Yet, it still depends on other factors, such as the weight of the robot, center of gravity, wheel size, etc.

Suggestion: SPG50-20K

Balancing does not necessary need encoder, but of course encoder will help a lot. Sure, you can try the SPG30E.

we have port the Kalman filter into PIC18F before, never try PIC16F before, but I believe it can be done.
