Video: Stanford University researchers create tiny robots that can pull a car

A mechanical wonder from the brainiacs at Stanford University. They have created a team of six tiny robots that can pull a car. Like ants, the uBots work as a team to move objects hundreds of times their size, like a frog being carried along by ants. The tiny robots use micro-adhesion and team-load sharing, to conquer the weight of the nearly 4,000-pound car. The Stanford researchers noticed ants can boost their lifting and dragging power by using three-out-of-their-six legs at once.
