Someone asked for a picture of how we mount sensors onto our robotic VX (Ironman Edition). We bolted a specially laminated sensor board, a.k.a. an old formica table-top :-) to the roof rack, then bolt the sensors to the formica tabletop... errrr sensor board. The blue "snorkel" is used to route wires from the sensors to the inside of the vehicle (the side window is replaced with a transparent acrylic panel and the snorkel is attached with a seal to the panel).
