more-inScientists have developed a tiny, soft robot with caterpillar-like legs that can carry heavy loads and could be used to deliver drugs in the human body. The robot has hundreds of pointed legs, measuring less than a millimetre. The robot’s body thickness measures approximately 0.15 mm, with each conical leg measuring 0.65 mm long and the gap between the legs measuring approximately 0.6 mm, making the leg-length-to-gap ratio around 1:1. Laboratory tests showed that the multi-legged robot has 40 times less friction than a limbless robot in both wet and dry environment. Our multi-legged robot shows an impressive performance in various terrains and hence open wide applications for drug delivery inside the body,” said Wang.
