How much weight can insect-sized robots pull?
Answer: 2,000 times their own body weight
Engineers at Stanford University created tiny robots called MicroTugs that can pull and lift objects more than 100 times their own weight. Some of the strongest robots developed, however, can pull objects 2,000 times their own weight, the equivalent of an average human pulling an object that weighs 352,000 pounds, like an adolescent blue whale.
