Is the Wireless Controller example in RobotC pretty much the same as the Driver Control program that is already included in the Brain? Wanted to make some changes to the Clawbot, and I thought that would be a good template to work from.

Yes, the “Advanced 2-Joystick Drive” sample program is probably the closest to the default “Driver Control” functionality in the VEX IQ system. We’ll have a more comprehensive sample that will emulate all of the behavior of the “Driver Control” for individuals who wish to customize it (just like yourself) in a future preview version.
