I thought the chassis of the cRio was tied to 24V.

Even if on one robot the chassis is connected to 12v and on the other it is connected to gnd, nothing would happen if these two robots touched each other. Sure, you'd be able to read 24v between the (-) terminal of the first robot and the (+) of the second if you stopped the match and walked out there with a voltmeter, but there is no complete circuit for current to flow through. Both the (+) and (-) of the same battery would have to be connected the different parts of the chassis and/or frame for any current to flow.
