I must say seeing this on YouTube reminded me of a couple of pigeons I watched while sitting in that magnificent Thames-side boozer, The Cutty Sark in Greenwich. It's worth turning up the sound.
This YouTube clip shows a couple of robots equipped with XMOS 4-core chips called G4 which support 32 concurrent real-time tasks and service 400 million events per second.
That's a hell of a lot of servicing.
