Robots with synthetic muscles

Robots using artificial polymer “muscles” are real slowpokes, as the polymers react a hundred times slower than human muscle. But in the future, robots could run circles around humans, with synthetic muscles 1000 times faster than ours.

The possible breakthrough comes from work showing how the polymer muscles work at a fundamental level, and suggests a way of triggering them that could make the muscles less bulky and vastly quicker.
