Soft robot muscles with origami skeletons can lift 1,000 times their own weight
Soft robotics has been a promising field of research for years, but these squidgy and flexible creations have been held back by the absence of one important characteristic: strength. Now, scientists from MIT CSAIL and Harvard’s Wyss Institute have come up with a way to give soft robots some power — by outfitting them with rigid origami skeletons.
In a paper published today in the journal PNAS, researchers describe a new type of soft artificial muscle that could be used to build soft robots. Each muscle consists of a sealed bag filled with air or fluid, containing a folding origami structure that functions as the skeleton. When the pressure inside the bag is reduced using an electric pump, the whole structure collapses and contracts, just…
