First off, take a second and calm down. One of the important things to remember about robotics is that your robot isn't thinking on it's own it is only responding to commands that it has.

You touched upon a few different things that are going wrong and the trick is you need to isolate each problem to solve it.

The first thing I would do is re-download the master code. This will flash the firmware and upgrade your controller.

The next step would be to redownload the default code.

Then check all of your motors, RX connection and robot to make sure it is setup properly.

At this point try your robot to see how it functions. If any of the strange operations continue it is possible you have a faulty controller. In my experience there are very few times that the vex controller is at fault but it does happen.

If the robot functions the way that it is supposed to the problem is most likely in your usercode. Without knowing the specifics of your robot I can't give you any advice about that. If you reach this point I suggest you post your code or easyc file so that others can help you to find the problem.

Relax you have come to the right place and we are here to help.
