That being said, most robots are either really clumsy or highly specialized to their task (and a little boring). The largest problem in robotics is the attempt to mimic human movement and behavior while controlling so many degrees of freedom in the joints and maintaining balance.
Imagine this, the face has more than 22 muscles per side. Legs, feet, arms and hands have many more than that. If you are a robot brain you’d have to control each movement of each movable part…and keep your balance by predicting how each movement will change the balance of the robot!
But that’s what makes this video of Sony’s QRIO robot all the more fascinating. The robots are dancing…and very human like too! You really have to watch the whole thing.
