Wixel used with Arbotix Commander V2

This post in the Trossen Robotics Community forum shows a pair of Wixels are added to an Arbotix Commander V2 remote control, allowing it to send its signals to a computer. The author gives us a nice compliment:

The most significant was our move to Las Vegas, which represented a commitment to doing this thing for real. This past Sunday was the 10-year anniversary of arriving in Las Vegas, so I figured I should commemorate it by putting up some old pictures. Continued…
