Ball Balancing Table
My version of the ball balancing table. A camera tracks a ball on a tilting surface, a PID controller computes the servo angles, and the servos tilt the table to keep the ball from falling off.

How it works
See
A camera tracks the ball’s position on the surface.
Compute
The PID controller turns the position error into servo angles.
Tilt
The servos tilt the table to keep the ball from falling off.
Then the loop repeats with the next camera frame.
