Light Painting with a 3pi Robot
Photo of my Pololu 3pi robot following a course laid out with black electrical tape.. The robot made two complete laps of the course during the 20 sec exposure. The robot has blue leds on the bottom and a red and green led on top. I also briefly shined a white led flashlight on the robot at the start of the exposure so you can see the robot surrounded by a white ring at the top of the course.
