The other day my team and I were competing at a local qualifying regional we finished the qualifying rounds with a win loss record of 6-2. Both of the matches we lost we experienced the same problem where shortly after it has been switched into driver control the robot would stop, becoming completely unresponsive and just continue to run two of our motors. The VEX official told us it seemed as though it could be a programming error and to trying just loading drive code onto the robot and run no autonomous. We did this for the quarter finals and in the first match (of quarter finals) we had a problem that occurred at our previous tournament where when the robot we enabled into driver mode we had no control what so ever. But it couldn’t be a problem with the code because if we reset the robot and tried to drive without being plugged into the competition switch everything functioned perfectly.
I am wondering if anyone else has experience these problems and how might I be able to fix this? Because I don’t think it can be a programming error if we made a new program that just contained driver code using the basic built in driver functions.
Do you think the Cortex is probably just faulty? Should we just change the cortex?
