Artificial muscles give soft robots superpowers. Researchers have created origami-inspired artificial muscles that add strength to soft robots, allowing them to lift objects that are up to 1,000 times their own weight using only air or water pressure. Consisting of an inner 'skeleton' folded into a specific pattern and enclosed within a plastic or fabric 'skin' bag, these muscles can perform a greater variety of tasks and are safer than other models.

We are getting very close to cyborg and robotic humans that walk around us but this will remain for the rich for a long time as the average guy will probably not be able to afford artificial muscles or a robot with artificial muscles.
