When I had my robotics practice today my first match went well, but we queued in for our second one, and all of a sudden the backwards on the controller only powers one motor. So far I have done the following: replaced the motor; replaced the connector to the motor; replaced both sides panels for the drivetrain; redownloaded the code; replaced the code. It seems like we can’t do anything. Please help, I can send pics and or videos if needed.

Try using a different port. The ports on the robot brain sometimes give out.

We had something similar happen in our first tournament and it ended up being the driveshaft sheared off. The small end was stuck in the motor so at first glance, it was hard to realize that’s what had happened.

Sound is always your friend, if you turn the wheels, do you hear the motor turning? When we build robots and they are done with the drive train, I have them stop and spin the wheels. I remind them that that is the sound they want to hear, and checking the drive train should be a step in their pre-match process.

Pictures or a video would be good.

I have found out the solution during my school day. I found out that our entire brain was dead because when I tried to run it, nothing worked, so, after that I thought to change the brain. It works perfect. I’m assuming that the brain just died or something, but I have no idea. I will run tests on it when I get to it

When I did run it, there was this really annoying screech, like an axle was grinding on something, and that’s why we thought it was our craftsmanship, not our coding. In my other reply I found out it my brain probably died.

Sorry for the wait but what happened is our battery port on our brain were fried (overuse) and only had some of the ports working. I tested this with a power consumption test from the brain and it came back as a much lower one than other tests on different gen 2 brains. We had to switch the battery ports, both positive and negative, and tested that and it works now.
