Robot keeps crashing?

The robot keeps crashing and we don’t know why, although we think it is a hardware issue, since it usually happens like when we nudge the robot a bit or drive, a wire might be coming loose? We just want confirm here and see if anybody else has ideas.

The driver station is losing communication with the radio. Therefore the problem is somewhere between the battery and the radio.

Investigate the connection between the radio and the VRM. It should be plugged into the 12V 2A port on the VRM. Make sure that the cord is seated as well as possible, as it is quite easy for cords to pop out of the VRM. That’s the first thing I would check. If that isn’t the case, make sure your ethernet cables are seated well. Maybe reconfigure your radio to work on the 5 GHz wifi instead of 2.4 GHz if it isn’t already. Let me know if any of these things work for you.
