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:

Ten years in Las Vegas

Starting with the move from our dorm to an apartment in Watertown, Massachusetts, Pololu has moved or expanded ten times. 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…
