I missed the show yesterday, I had an important meeting to go to. I just found that Nova put the video up on their website, so if anyone else missed it you can watch it here.
http://www.pbs.org/wgbh/nova/tech/rise-of-the-robots.htmlOne thing I found interesting, was how difficult it is to make a humanoid robot. The larger they are the heavier they are, and that makes them even more difficult to move without falling down. A man sized robot can end up weighing over 400 lbs! OTHO, a smaller humanoid robot is easier to build that can walk and perform human like movements. Honda's Asimo is one of the smaller sized humanoid robots. Interestingly he is actually the same size that Astro was described at, about 4.5' tall.
