It makes little sense to try to charge the Kangaroo on the robot during a match. It has sufficient battery life on the COTS battery to survive the match and be charged in the pits easily.
This is the real weight and size value to it versus say the ODroid XU4. With the ODroid there's no COTS battery. So it must have power from the robot. It is very likely I can place in the footprint of the face of the Kangaroo the ODroid XU4 and the support power system but it will be heavier and thicker by some amount. On the other hand the USB to Ethernet dongle will make the face of the Kangaroo a little larger. Price wise the Kangaroo plus the USB to Ethernet dongle are in line with the price of the ODroid XU4, the case for it, and the old D-Link DC/DC converter. If one adds a boost converter to the Odroid XU4 system then the ODroid XU4 is slightly more expensive to use for this. Ubuntu on the ODroid is 32bit and Windows on the Kangaroo is 64bit. Not that I think the word width is the big issue here. The National Instrument software may work with the Kangaroo but with the ODroid XU4 you'll probably use OpenCV.
I am not sure how long the boot and shutdown on the Kangaroo are. If it is left on between matches it might not matter.
