From the great IEEE Spectrum Automaton blog:
We’re used to thinking of robot swarms as consisting of lots and lots of similar robots working together. What we’re starting to see now, though, are swarms of heterogeneous robots, where you get different robots combining their powers to make each other more efficient and more capable. One of the first projects to really make this work was Swarmanoid, with teams of footbots and handbots and eyebots, and researchers presented a similar idea at IROS earlier this month, using an AR Drone to help a swarm of self-assembling ground robots to climb over a hill.
