The Pololu 3pi robot is a complete, high-performance mobile platform. It features 2 micro metal gearmotors, 5 reflectance sensors, an 8x2 character LCD, a buzzer, and 3 user pushbuttons all connected to a C-programmable ATmega328 microcontroller. It is even capable of speeds exceeding 3 feet per second. 3pi is a great first robot for ambitious beginners and a perfect second robot for those looking to move up from non-programmable or slower beginner robots.
The 3pi robot is designed to excel in line-following and maze-solving competitions. It has a small size (9.5 cm/3.7" diameter, 83 g/2.9 oz without batteries) and takes just 4 AAA batteries (not included), while a unique power system runs the motors at a constant 9.25V independent of the battery charge level. The regulated voltage allows the 3pi to reach speeds up to 100 cm/second (3 feet/sec) while making precise turns and spins that don't vary with the battery voltage.
There are also sockets for Wixel and XBee wireless serial modules, prototyping space for additional sensors and electronics, 8 more user-controllable LEDs, and much more. An external AVR ISP programmer is required to program the 3pi. Also be sure to check out the step-by-step on the Jameco Workshop page.
