The Milwaukee School of Engineering (MSOE) underwater robotics team has been building remotely operated vehicles (ROV) to compete in underwater ROV competitions for several years. In the past, they have created custom motherboards that our 18v15 Simple Motor Controllers could plug directly into:

The team is now using our newer G2 High-Power Motor Driver 18v17, which allowed them to save space in the newest iteration of their motherboard.

Our customer Robert sent us this spectacular image of NGC 1073 from his backyard observatory after we helped him get a SPDT Relay Carrier working with his Mini-Maestro 18-Channel servo controller. We thought it was pretty cool, so we asked him a bit more about how he captured it and how he is using the Maestro in his observatory. Continued…
This robot, created by theophil on Let’s Make Robots, uses a Rover 5 chassis with encoders, a MinIMU, sonar sensors, and a few expansion plates to do room mapping. Theophil modified the chassis to use Dagu Wild Thumper wheels, and made a custom 3D-printed adapter for connecting the wheels in a compact way. The program for the robot, which is available on GitHub, collects data from the sonar sensors about how far away objects are and creates a grayscale map where the darkness of a pixel corresponds to the robot’s confidence that an obstacle exists in that spot.
Example map made by theophil’s mapping rover.
The program also includes a movement algorithm meant to drive the robot along paths that take it close to many obstacles to increase the accuracy of the sonar sensors. More about theophil’s room mapping robot can be found in his Let’s Make Robots post.
Remember my super cool sumo robot? My sumo robot is different from regular sumo robots. It’s like my sumo robot is in the top percentage of mini sumo robots. Continued…
This “World’s Fastest” Rubik’s Cube-solving robot uses six DRV8825 stepper motor driver carriers, one for each face.
VertiGo is a novel robot designed with one main goal: the ability to drive on floors and walls, even if the walls aren’t perfectly flat. To accomplish this, it uses tiltable propellers for propulsion rather than motorized wheels. The propeller tilting is controlled by two Pololu Jrk 21v3 USB motor controllers with feedback. Students at ETH Zurich made this robot in collaboration with Disney Research Zürich.

For their senior design project in the spring semester of this year, a team of Mechanical Engineering students (the Tuggiteers!) from Purdue made a remotely-controlled plane-towing vehicle that uses one of our step-up/step-down regulators. The team shared with us this video of their final review, which demonstrates the vehicle approaching, connecting to, and towing a single-engine aircraft:
This next video captures their vehicle’s first test. An on-board camera allows you to get a 1st-person view of the latch actuating and gripping the aircraft wheel:
We are always excited to see our parts getting used in cool projects, and we were especially excited to see this because it looks way easier than doing it the usual way:

There is a nice recap on the Raspberry Pi blog of the Pi Wars 2015 competition that was held last weekend on December 5th, 2015. It is a robotics competition held in Cambridge, UK that focuses on robots controlled by a Raspberry Pi. I noticed a lot of Pololu parts on the robots in the videos. Just a few examples are wheels and tracks, motors, and reflectance sensors. I didn’t see any A-Star 32U4 robot controllers in the videos, but I think that would make a great controller for a robot in the next competition because it can be used as a Raspberry Pi expansion board!
