The more I read about robots, the more I think that the most useful of them will come with functionality and scale that are very different from human abilities and size:

The surgeons of tomorrow will include tiny robots that enter our bodies and do their work from the inside, with no need to open patients up or knock them out. While nanobots that swim through the blood are still in the realm of fantasy, several groups are developing devices a few millimetres in size. The first generation of "mini-medibots" may infiltrate our bodies through our ears, eyes and lungs, to deliver drugs, take tissue samples or install medical devices.

Most importantly, new diagnostics and control technologies need to be invented to guide the bots in these new applications.
