It has a small size (9.5 cm\/3.7\" diameter, 83 g\/2.9 oz without batteries) and takes just four AAA cells (not included), while a unique power system runs the motors at a constant 9.25 V independent of the battery charge level. The regulated voltage allows the 3pi to reach speeds up to 100 cm\/second while making precise turns and spins that don’t vary with the battery voltage.\u003c\/p\u003e\n\u003cp\u003eThe 3pi robot makes a great platform for people with C programming experience to learn robotics, and it is a fun environment for ambitious beginners to learn C programming. At its heart is an ATmega328P AVR microcontroller from Microchip (formerly Atmel) running at 20 MHz and featuring 32 KB of flash program memory, 2 KB RAM, and 1 KB of persistent EEPROM memory. The popular, free GNU C\/C++ compiler works perfectly with the 3pi, Atmel Studio provides a comfortable development environment, and an extensive set of libraries provided by Pololu makes it a breeze to interface with all of the integrated hardware. The 3pi is also compatible with the popular Arduino development platform. We provide a number of sample programs to show how to use the various 3pi components, as well as how to perform more complex behaviors such as line following and maze solving.\u003c\/p\u003e\n\u003cp\u003eThe diagrams below highlight the important features of the 3pi.
