Transformers Anyone?

This article is like childhood all over again. Apparently some researchers at USC have created a robot which can form itself out of other robots. So it's really a bunch of robots that link together when they need to do something. Sound familiar? To me, it sounds a lot like the transformers from when we were growing up (I think the show might even still be on), but these things actually work. As a sign of faith, the researchers scored $8 million to continue their research. The idea is that these little guys will replace the rovers on Mars, and elsewhere. They can join together to act as a rover, and then do other things when they're done getting around. If this works, it means a greater variety of research could be carried out, since the robots have more versatility. It would also apparently just increase the number of scientific tools we could send up, because currently we take up a lot of space sending redundant parts. This is why the rovers last so long. These robots are all identical, so they are inherently each others spare. This idea is very interesting to me, and obviously to a lot of other people or they would not be getting so much funding.
