3pi Robot + USB Programmer Combo
An AVR programmer such as the Pololu USB AVR programmer is required to program the 3pi robot. This combination deal includes the USB AVR programmer with the 3pi robot, as well as a 6’ USB A to mini-B cable for connecting the programmer to a computer and a 12" 6-conductor ribbon cable for connecting the programmer to the 3pi.
The 3pi is powered by four AAA batteries, which are not included. We recommend rechargeable NiMH cells, which may be purchased from Pololu or at a local store carrying electronics.
