Replicating the way ants work together to move objects hundreds of times their weight, scientists at the Biomimetics and Dexterous Manipulation Laboratory (BDML) Stanford University have created a small team of micro tug robots. Recently, a team of just six of these impressive microbots—weighing in at a combined 100 grams—was able to pull an entire car with a human sitting inside, or about 1800 kilograms. The bots make use of slow, overlapping tugs to produce the most effective force. Watch them move the car on YouTube.
