The dancing robots actually performed in a laboratory at the University of the West of England (UWE), where this is part of a long-term project which united engineers, philosophers and cultural theorists in order to analyze what the machines revealed. The robots in question were tiny in size, sporting two-wheels and is known as e-pucks, and were released in an arena to interact with one other. Every single bit of interaction has been recorded on video thanks to an overhead video camera.
Of course, these robots are not perfect in any sense, and they do make copying errors as well – just like us humans. Still, it is interesting to see how robots and culture are able to work together.
