Re: Sensor Recommendations
This is an odd one...
For the Aim High challenge, we built a rotating turret that could shoot balls in a wide range of directions. It required motors and stops for both the X and Y direction for the turret, and the initial design depended on mechanical limit switches. When we tried it in competition, the switch arm often bent out of shape, allowing the motors driving the turret to stall and pop breakers. The solution to this problem (which worked wonderfully, I might add) was to install reed switches and magnets at the extremes. Vibration-induced false positives really never became a problem, which surprised us all. Future iterations of the robot are supposed to use hall-effect sensors (a reed switches' modernized cousin), but they require power as well, so for a quick 'n' dirty fix, use a reed.
