Re: Banebots RS-775 Case Short

We had the same results. Even if we found a motor that checked out as "good", after some period of time running on the robot it would eventually short. Eventually every 775 we used became shorted. We went through about 6 or 7 of them I believe.


One other thing I want to add is in regards to what happened at the beginning of the issues with the 775 last year. While BaneBots is doing the right thing now and standing behind their product, this was not originally the case. If you go back in this thread to around posts #64 & 65, you will see testaments from teams here stating that BaneBots was not taking back their shorted 775 motors. Instead they were advising teams to do the "zap" method to fix them. While this method did usually give the motor a bit of a 2nd life, and they are now publicly stating they are taking them back and providing replacements, this was NOT the original tune sung when the problem first arose.

I am not trying to stir the pot or anything of the sort. Personally, I completely understand why some teams are choosing to not use BB components on their robots. We will be using components from BaneBots that are not 775s, and we certainly appreciate their support. However, our memory is not that short term, so we are cautious in our dealings with their components. We've had success with them in the past, and we've also had close to insurmountable failure.
