Xerox PARC Working On Modular Robots

An reader writes "I was watching Discovery Channel Canada last night, and they had a story about modular robotics that is being researched at Xerox PARC. Rather than build a single, large robot, project leader Mark Yim is working on small, autonomous bots that can work together to achieve a desired goal. When many of this bots are linked together, they call the result a polybot. "

cool idea, similar to nanobots conceptualizations

This project has been going on for some time now, it's been well publicized in the robotics community and is certainly an interesting offshoot of robotics. I saw a presentation at ICRA (International Conference for Robotics and Automation) last year. Very cool.

It strikes me as rather similar in approach to some of the nano-bot discussions I've read. I.e. build an "assembler" and use that to build other small pieces that can fit together modularly to do what you want. (that's kind of rough, but you get the idea) Interesting parallel in totally different research worlds, although modularity is hardly novel..

The approach does have it's challenges however, the number of independent modules arguably makes the complexity much higher per resultant functionality. A simpler robot could have achieved some of those configurations, and probably more efficiently (power,weight,computational, etc..). Similarly, most robots are rather specifically designed with some task in mind, making general purpose robots is an astoundingly difficult task because of the widely varying requirements of the physical world between different tasks.

I don't mean to bash, actually - I fully support this avenue of research and it's darn cool! Wish I had one..
