The Pololu 3pi robot is a complete, high-performance Multipurpose robot platform. It features two micro metal gearmotors, five reflectance sensors, an 8×2 character LCD, a buzzer, and three user pushbuttons, all connected to a C-programmable ATmega328 microcontroller.

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 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.

The 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 Atmel ATmega328P microcontroller 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.

Q: Will it be assembled? Where i will get the programmer and batteries? Questioned by tahmidzu, 10-Sep-2014

Yes. It is assembled. Programming can be done with our AVR programmer. Batteries should be rechargeable AAA batteries but those are not available at Techshop. Answered by A.R, 10-Sep-2014 09:45 AM

Q: When would be this 3pi robot available Questioned by Mohiuddin.rafiul, 31-Mar-2016

Q: do u have the proper programmer and cable to program this 3pi? if yes then plz also mention that product's name. Questioned by Rafid_007, 17-Jun-2016

To program the "Pololu 3pi Robot", you can use any AVR programmer. Such as: >> https://www.techshopbd.com/product-categories/avr-98764/2152/usbisp-avr-programmer-cn-techshop-bangladesh >> https://www.techshopbd.com/product-categories/avr-98764/214/avr-programmer-techshop-bangladesh >> https://www.techshopbd.com/product-categories/avr-98764/1351/pocket-avr-programmer-techshop-bangladesh But the programmer and "Pololu 3pi Robot" programming connector are not same. You have to use jumper wire to burn the program. Answered by FAHIM_REAZA, 19-Jun-2016 11:02 AM
