Do you find the world of robotics interesting? It's very easy to create a robot! With this 2WD Round Chassis for Robot Cart, a microcontroller (Arduino), some sensors and programming you will be able to develop the robot of your dreams!

Tamiya’s steel-ball caster is a good way to give a “third wheel” to a small robot powered by a differential drive. The kit comes with enough parts to make two casters, either 25 mm or 35 mm in height.

This acrylic expansion plate lets you mount a variety of components to your Rover 5 tracked chassis. The 3 mm wide slots covering the plate support many configurations of sensors and other robot components.

This compact expansion board plugs directly into the GPIO header on a Raspberry Pi B+, A+, or Pi 2 and provides an easy and low-cost solution for driving a pair of small brushed DC motors. Its integrated DRV8835 dual motor driver allows it to operate from 1.5 V to 11 V, making it a great control option for low-voltage motors.
