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.

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!

Hi, my name is Patrick. I am an engineering intern at Pololu and am studying at the University of Nevada, Las Vegas to earn a mechanical engineering degree. I decided to build a custom robot to compete in the recent LVBots mini-sumo competition here at Pololu. It was my first competition at LVBots. I started out by watching a compilation video of the previous sumo competition at LVBots since I had never competed in a mini-sumo competition before. My goal was to create a robot that could out maneuver other robots and had as few vulnerabilities as possible. To achieve this goal, I decided to build a robot that would be high speed and able to push opponents from both sides of the robot with a lot of force. The result of my efforts is the robot I call Covert Ops. Continued…
My robot, Roku, was the champion of LVBots’ August mini-sumo competition. While I didn’t have the time or inspiration to make it look like anything more interesting (like a Star Wars droid) or make use of especially innovative tactics, I think I managed to build a robot that not only is effective but also looks fairly clean and well put together. In addition, it’s a good demonstration of how the Pololu A-Star 32U4 Robot Controller can be used as a standalone main board for a small robot. Continued…
