Babybot

There are many conceivable and feasible techniques to give motion to a robot. In most cases

ordinary electric motors, servos and stepper motors offer the simplest solution. In particular if the actuators are required to deliver a considerable amount of power. But for very small objects other types of actuators also become suitable, such as the one used in this mini robot. The term ‘robot’ may be a little of an exaggeration in this case. This creature has to be controlled from the outside and does not have any other artificial intelligence, but the method of motion is quite unusual

and with a little modification could also prove useful in other projects.

BabyBot walks with the aid of four small PCB relays, which have been specially modified for this purpose..
