Machine muscle or "soft robots" are a new way that engineers are creating machines. The way these muscles works is very simple and very cheap. A team from the University of Colorado Boulder have proven this doesn’t need to be expensive; their brand new artificial muscle is a steal at 10 cents per device. The “muscle” works by applying a small voltage across hydrogel electrodes on either side liquid insulators pouches (these pouches can be filled with something as basic as canola oil).
The voltage creates an attraction between the two electrodes and pulls them together; displacing the liquid which in turn changes of shape of the pouch allowing it to push or pull levers, arms or any other articulated component. It is suited to carry out a variety of tasks – from picking up delicate objects to lifting heavy objects. In fact, the team claims the robot will be able to lift objects up to two-hundred times its own weight.
