Team of Six Tiny Microrobots Pulls a Car

A team of researchers from the Biomimetic Dexterous Manipulation Laboratory at Stanford University have taken their inspiration from ants that work as teams to move massive objects. They observed that the ants get great cooperative force by each using three of their six legs simultaneously. With careful consideration to robot gait, they demonstrate a team of six μTug microrobots weighing 100 grams pulling an unmodified 3,900-lb car on polished concrete. Part of this success is from the usage of a special adhesive that was inspired by gecko toes.
