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.

Textspresso text-enabled espresso machine
This text-enabled espresso machine uses the Zipwhip app to receive a text message for an order of espresso. An A4988 stepper motor driver carrier and servo are then used to rotate the cup up to the nozzles where the espresso is dispensed.
Heatsinking an A4988/A4983 stepper motor driver carrier

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

This autonomous, obstacle-avoiding robot is controlled by an Arduino and uses two 25D metal gearmotors, which are attached to a dual VNH2SP30 motor driver carrier.
Monitoring power consumption with the ACS715
This blog post by Steve Spence discusses using an ACS715 Current Sensor Carrier to monitor the current consumption of a ham radio when in emergency communication mode.
This laser-cut robotic arm is controlled by a Mini Maestro servo controller. By Szymon Kobalczyk, April 2012.
This balancing robot by Kristian Lauszus uses two 37D metal gearmotors with encoders that are mounted with gearmotor brackets and driven with a dual VNH2SP30 motor driver carrier.
Prometheus - a CNC Router Project
This CNC router features four of our A4988 stepper motor driver carriers. You can find more videos and information in this CNCzone forum post.
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…
