Pololu 3pi roboten är en liten och lätt (9.5 cm diameter, 83 g utan batterier), högpresterande, autonom robot, utvecklad för områden som "line following" och "maze-solving" tävlingar. Utrustad med fyra AAA batterier (ej inkluderade) och ett unikt kraftsystem som kör motorerna på en konstant spänning 9.25 V, 3pi är kapabel till hastigheter upp till 100 cm/sekund samtidigt som den kan svänga & spinna exakt som inte varierar med batterispänningen.
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.
For instructions on setting up and programming the 3pi, including sample code, contest ideas, and more, see the 3pi User’s Guide.
An external AVR ISP programmer, such as our USB AVR programmer is required to program the 3pi.
The 3pi is powered by 4 AAA batteries, which are not included. We recommend rechargeable NiMH cells (we do not sell batteriers).
