One of our distributors in New Zealand has created a small, inexpensive robot platform to be used with students in their technology curriculum (and no doubt for fun as well). Called the "BrainBot" it consists of a Freetronics LeoStick as the brain, which is mounted on a MindKits "brainboard" which controls the two motors and allows for various forms of sensor and other expansion possibilities. It's a fun project and should find uses in various lessons and homes as well.
So what is a LeoStick? It's the Arduino Leonardo-compatible board that's cheaper and smaller than the original:
Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.
