Technology Review recently produced a video documentary on work being done with artificial muscles and its potential applications to robotics and possibly toys as well. It is an interesting video with scientific background into how the artificial muscle is actually made, and how it can improve current robots and devices. It seems the materials being used to make the artificial muscle will be much lighter and take up less energy and space to work, and also make any movements by the robots more fluid.
