Using small stepper motors and wheels from a hacked lego mindstorm robot, the boys have produced a powerful remote controlled device.
A raspberry pi computer is used to receive the blue-tooth commands from an android phone. The boys used the python programming language to process the signals and then provide output to the powerful stepper motors that drive the wheels. Two small 9 volt batteries provide the power for both the raspberry pi computer and motors.
Mr Scales said this is exactly what the hackers and makers club is all about. Combining technology such as Android phones, Raspberry pis and python programming with some basic electronics can lead to some great projects such as this one.
