Introduction to the 3pi robot

To see for yourself what the 3pi is like, please take a look at the video below, which introduces its basic features and operation.

Pololu 3pi Maze Solving

The following video shows a 3pi prototype autonomously solving a line maze. It first runs through the maze executing a search algorithm, keeping track of which way it is turning at intersections and discarding paths that lead to dead ends. Once it finds the end, which is marked by a solid black circle, it determines from memory the best path from start to finish and on subsequent runs aggressively drives that shortest path. This is just one example of what the 3pi is capable of.

The Pololu 3pi participating in a line-following exhibition

This unedited video shows six 3pi prototypes simultaneously participating in a line-following exhibition at a robotics competition. The robots were all programmed independently. Last one remaining on the line wins!

Pololu 3pi Spinning Line Follower (by Byon)

Byon wrote a program that turns the 3pi into a spinning line follower that blinks its red LED every time it’s over the front part of the line.
