Here is a summary of recent advances in regards to robotics. Some have been mentioned before on this blog, but are summarized here.
Currently, robotic muscles move 100 times slower than ours. New research could make robotic muscles 1,000 times faster than human muscles — with virtually no extra energy demands and the added bonus of a simpler design. Conjugated polymers can actuate on command if charges can be sent to specific locations in the polymer chain in the form of “solitons” (charge density waves).
