Robot security guard 机器人保安


Meet Bob, the metal minder.

He's on patrol in the offices of the security company G4S.

Bob does a 3D scan of each room to check if anything's missing.

This technology is just one of many new developments in the UK's robotics sector.

And while he's no substitute for a human security guard, Bob has already learned some basic office etiquette.


"Thank you, I will be on my way."
