CES 2015: Keecker robot on patrol with a projector

We've heard of robotic vacuum cleaners patrolling the house - but what about video projectors?

That is the idea behind Keecker, a robot controlled by a mobile device, which can travel round your home projecting films, computer games and even "digital wallpaper".

The Paris-based start-up has raised more than quarter-of-a-million dollars for the idea on Kickstarter.

Leo Kelion talked to Keecker's Alix Mobuchon to learn more about the concept.
