If you want to watch a group of robots that can dance in synch while "using a quorum sensing mechanism", you're in luck.
Check out this video, courtesy of Aldebaran Robotics, in which they've teamed up with MIT's Nonlinear Systems Laboratory to perform such a feat. The goal of the team was to see if they could synchronize a group of the Aldebaran's NAO robots, but also "to allow robots to join or leave the group at any time (for example, a fallen robot should be able to stand up to rejoin the choreography)."
More details on the project, including a discussion of the quorum sensing mechanism and contraction theory, is available here.
