I have a Revolution Six that I have used for one of my robotics classes the past two years. Last year, Six worked fine. This year, for some reason, it is burning out lever servo motors. I have gone through 5 already this year on the same robot. The burnouts occur on different ports, and happen at different times. I asked my students what they were doing when the motors stopped working and they said that they were just using some of the built-in movement scripts.
These burnouts are becoming quite expensive to handle. Has anyone experienced this situation before? If so, what can be done to rectify the situation? Any help would be greatly appreciated. Thanks.
