The Rockit is a simple 3-wheel device with a suitably futuristic appearance. It includes basic touch sensors and a condenser microphone for sensing sound. If it detects it has bumped into an object then it will reverse and make a left turn in an attempt to find its way round the obstacle. Alternatively this action can be set off at any time by a loud noise such as a clap.
As robots go it's not very advanced. As with most kits, the fun comes from seeing something that you've "built" yourself in action. In 2001 the Rockit Robot was chosen by the Children's Institute For Childhood Resources as one of the "100 Best Children's Products" and "10 Best Software/High Tech Products".
Make sure that you buy the right version and always put safety first. Children should never be allowed to use a soldering iron unsupervised.
