Mark,
You may not "ground" any electrical components on the robot. If static is the actual cause, a "drain" might help pull some of the static from the belts to the robot frame. This usually takes the form of a flexible metal brush that wipes on the belt and is connected to the frame of the robot.
However, what you describe really sounds like a power problem. Often there is a whisker (a single strand) that pulls out of a connector either at the PD or at the Crio. This can add noise to the power supply that might interfere with Crio operation but often causes Crio reboot. Are you using the power convertor to power the radio? This is essential. Check that all wires are properly terminated (any hardware is tight and all crimps are correctly crimped) and insulated. The Dlink also needs to be mounted away from motors. While brush noise does produce interference, most motors are closed enough to shield the noise. The robot rules do allow you to place a 1mfd (or less) non-polarized cap across motors input terminals to help eliminate any other RF that might be generated.
There is one last item you can add for static. You can drag a bare wire underneath the robot that is connected to the robot frame. In most cases this does nothing as the carpet has no conductive fibers. If you add this wire, it may not extend outside the frame perimeter at any time.
