Muscle coordination can be mimicked by electric motors – it could lead to improved robots

People often take their muscles for granted. They pick up a bag, tighten a grip, climb a hill, hold a cup of coffee and the body quietly adjusts force, speed and position without the person ever thinking about it. Muscle turns chemical energy into movement . It is able to produce force smoothly and reliably, even though it is built from huge numbers of tiny molecular components. When the load changes, muscles don't simply wobble or fail.
