Yet more proof that the Japanese rule the world when it comes to hilarious and slightly sweet robots. The latest purports to be a security robot, but I suspect that you’re more likely to be incapacitated with laughter at this dinky machine than genuinely caught.

It travels at 10kph, has microphones and body heat sensors, and it’s controlled by an external operator. It’ll catch your thief, but you’ll need a real person on the scene before the person can make it out of the net. It’ll be available in a couple of years, and will cost ¥800,000 (£6,700 or so).
