The Cambridge Brainbox Walking Robot demonstrates how rotary motion from an electric motor can be turned into linear motion in the robots legs. Easy to do and great fun, the gearbox even has variable ratios to allow you to experiment and find the optimum gear ratio for a natural walking speed.
The Cambridge Brainbox Solar Racer is a great new kit to demonstrate environmentally friendly transport to children. The kit allows you to build an electric motor powered car with a photo voltaic panel to generate the required power from sunlight (or a normal light bulb).
