Re: Side of Drives Giving Out

It is quite possible that over the months since build, hardware has loosened and mechanical parts have moved. This could cause friction in the drive that was not present earlier in the season.
Since you state that the robot can drive after a few seconds, my money is on the Jag over current protection.
So if we are activating the current protection circuit in the jaguar, is that an issue that can be resolved by adding a second CIM to the drives?

I did notice a Jaguar flashing red when we lost driving ability, but I'm not sure if it was the Jaguar responsible for the drive motors. I'll check that Thursday. When testing, I'll also have someone watching the Jaguar for the right drive motor, to see what happens when that side fails.

I will also see if we can pull together and get an effort to perform maintenance on the mechanical parts to help adjust the friction in the drives.

Also, thank you very much, Justin and Nick! I really appreciate the offer. Our goal right now is to be able to show up to Ruckus and not need extensive repairs, so that's what we're working towards. I really do appreciate the offer, and I will let you know if we will need to take you up on it
