There are two things you need to see related to robots:

The first is a video of a 1ft. tall humanoid which is extremely flexible. I think the movement is scripted (as opposed to reacting intelligently to your environment) so that is too bad.

The second is a cheesy video of what a robot policeman might look like. I think that it misses the point, in that robots are scalable more than humans, so showing 100s rather than a single robot makes more sense. Also, it talks about "developing" nations. If you had a robot which could act much like a cop, you could also have robotic construction, which would make the time for development much smaller, e.g. building infrastructure in farming, roads, buildings, sewers, electrical grids, etc. would be easy and cheap.
