Yeah, it seems as if our driver looses all control of every system on the robot. I'm not 100% sure about the other aspects though (i.e. shooter or our feeder for our shooter), but its definitely something I would like to play around with during our first match tomorrow. I want to say its the entire robot.
As for the disconnecting part, what happens is that our driver is able to move it one second and the next he isn't able to move at all. He can push the joystick down all the way and it won't budge. If he continues to attempt to do so, then occasionally it'll move like inches forward. It sometimes reconnects and other times disconnects.
Here's a video of it:
