48v3KW Motor Controller for self-balancing robot
newInRobotics:
Low center of gravity is good for static balancing, it makes object stable, for dynamic balancing the higher COG is - the better. If weight below axle is bigger than weight above it, robot won't be able to move as it's not inverted pendulum anymore (it's normal pendulum with COG at it's lowest point). Simple proof, try balancing a plain stick placed perpendicular to to Your hand plane, then try doing same thing however with significant weight being added to the higher end of the stick. Which way is it easier to keep stick in balance?

Try with a hammer - fast way to get the idea :)

Hammer is a stick with weight on one end :p

Doesn't really matter, since it's a hub motor attached to the wheel. All the weight will be above it no matter what I choose.

Exactly and the weight comes already attached, ready to do balance tests (rather than having to fiddle with a stick, a weight and duct tape ;))
