Jared,

I would not be surprised if the RS-775 case shorts were causing your robot to die. We have had an endless stream of issues arising from these motors. Every single motor we have ordered from Banebots has come with or developed a case short. (Some of the motors were not tested until we had already used them. It's not our standard operating practice to test motors for case shorts prior to usage. We've now adapted our procedures to assume manufacturing incompetence.) Just in Pittsburgh alone these motors led to multiple trips of our main circuit breaker, trips of the motor breaker and possibly a fried cRIO. (The cRIO is definitely fried, but we're not 100% sure it's the fault of the Banebots. Although I have no idea why we're giving them the benefit of the doubt at this point.)

I highly recommend that any team who experiences weird issues with their robot to check the resistance from the leads to the case of their Banebot motors. Please spread the word to teams who don't read Chief. We saw a lot of teams in Pittsburgh who were having issues, and had no idea it could be traced back to a case short.
