Re: pic: Vision Aim Ping Pong Ball Robot
For scorekeeping,
Detecting when an IR beam is blocked by a ball that falls into a funnel and then into a "detection pit" should be pretty easy (As easy as anything is in these situations).
To account for changing ambient light, instead of looking for a single pair of blocked/unblocked values, you could turn the IR transmitter on/off frequently, and keep track of the changes in received signals (when they stop changing, the beam is blocked (or the receiver is saturated)).
