pi2golitedocsThe Pi2GoLite is a great robot from 4Tronix.

As well as the usual two bi-directional motors, it has left and right line sensors, left and right obstacle sensors, an ultrasonic module, 2 pairs of controllable LEDS (Front and Back) and a little switch on the side.

As well as the built in hardware, it has 2 sets of pins that can be used to control servos as well as an Adafruit compatible I2C connector for connecting further I2C modules such as the PiDisp

The robot itself is powered from 6xAA (NiMH recommended) which goes thru a very efficient switching regulator which maximises battery life.
