since some long time I am wondering, if something like this:
could be controlled by a microcontroller, perhaps P1?
The motion shall be done by two servos motors.
But what is the most easy way to detect the position of the ball?
The ball shall have a diameter of 6...12mm and could be made of wood, glas, steel....
The board shall be made of plywood, bores have to be applied.
The position must be known with perhaps 5Hz and perhaps 1mm/150mm accuracy in two directions on the plane. Calibration regarding linearity would be possible.
So I would be grateful for ideas, how to measure this!
Thanks in advance!
