The LightRobot is a 3pi Robot that has been modified with RGB LEDs, an RN-41 Bluetooth module, and a sonar range finder that is controlled with voice commands and the accelerometer from an Android phone. The source code for the robot and the Android app are also available on the project’s GitHub page.

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:

Not to be a shill, but that was easier to set up than any MCU + Xbee configuration I’ve seen.

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…
