I have no doubt that this works (with the expected technical issues). I merely doubt as to whether or not it would be considered legal on a competition robot connected to a motor (at first glance R47 would not lead you to believe the radio is excluded either but it is excluded I asked in the official Q&A before this year). The closest topic I found from 2009 was this:

It merely states that the current sense resistor needs to be a very small value. It does have mention (by Al) of using the wire as a current sense resistor. Has anyone actually fielded this on a competition robot using the cRIO to process the measurements? There seems little sense to me to go back and forth over the myriad details (as often happens) if it might not be legal on the field.
Back on the topic of the Jaguar itself: is there a poll by team number of the teams that intend to use Jaguars on competition robots this year? I was helping a student make something that was an accessory to the Jaguar and with all the admirable effort IFI is putting in to these units I wonder if the number of teams using them is actually getting smaller. I am neither for or against the Jaguar in particular myself.
