While it could be a mechanical or a programming goof, it was about 4 weeks into the build season when we were testing our arm. As a safety precaution we had put limit switches on the robot to make sure nothing went wrong. Everything was going great till one day the arm started not stopping at the limit switches, luckily i was manually controlling the arm or it would have been bad. As it turned out one of our mentors switched out a limit switch for some reason. After testing about 5 or 6 different limit switches and spending quite a bit of time rewriting our code i turned to the mentor and asked if the switch was normally open or normally closed. As it turns out when they switched them out they switched to normally open. So it was about 2 hours of troubleshooting to find the little thing that was killing us.
