Collective Control of m3pi Robots
This project used m3pi robots with Wixels attached for wireless communication. It used a Java program which calculates optimum routes for each robot and schedules them. The scheduling process is based on the A*-algorithm. To avoid deadlocks and collisions it uses automata, theory and a Java API called Supremica developed at Chalmers University of Technology in Gothenburg Sweden.
Line Following With Gaps and Obstacles
This 3pi robot, customized and programmed by Jan Matas, can follow a black line with sharp corners, gaps, and obstacles. The text translates to: “We have seen many robots that try to follow a black line. And how have they performed? Sadly… But today, the revolution is here. Hello my name is Pololu 3pi. I am the robot preparing for Robocup jr. 2010 in category rescue.”
3pi as a Wall-Following Robot
This video shows a 3pi robot that uses two Sharp distance sensors to follow walls on its left and drive around obstacles in its way. Please see our sample project for information on how to make your own 3pi wall follower.
3pi Pool Racer at LVBots Challenge 4.5
This competition pits multiple robots against each other on the same course. The goal is to be the fastest to complete three laps around the obstacles.
This video shows a 3pi robot being controlled via signals from a two-channel RC receiver. Please see our sample project for more information on how to make your own RC 3pi.
3pi Fire Fighter
This video, uploaded by myblack60impala, shows the first place entrant in the St. Louis Robotics FIRE mini comp, a small scale fire fighting competition.
This video shows a school project by Group 9 at University West (Trollhättan, SWEDEN) in fall 2009. The 3pis use Sharp distance sensors to simultaneously run on the same line and maze courses without colliding.
Another Wall-Following 3pi
This video shows the final version of a school project to turn a 3pi robot into a wall follower using two side-looking long-range sharp distance sensors and a front-looking sonar sensor. For more information, please see Mathew’s 3pi blog, which tracks the progress of the project and provides source code and pictures.
Home-made m3pi Controlled by Bluetooth Keyboard
Kazuhiro Ouchi mounts an ARM mbed development board on a 3pi expansion board and uses it to receive commands from a Bluetooth keyboard and send serial commands to a serial-slave 3pi. He wrote an mbed notebook page (in Japanese).
Terry, also known as lufamseed, made this Micromouse 3pi robot by that uses distance sensors and encoders along with a flood-fill algorithm to find the shortest path through a walled maze.
Walled Maze Solver 3pi
Brian Jones made this walled maze solver 3pi robot using distance sensors.
3pi Sound Follower
MrDreamBot made this remote-controlled 3pi that uses Wixels and custom PC software written in Java.
