If you're wondering what the robo-apocalypse will look like, don't worry, it'll all happen so fast you won't be able to see it.

This compilation of robo-sumo from Japan from Robert McGregor makes the regular 'Robot Wars' look like a game of tiddlywinks by comparison, and is proof that when the robots come take over, they'll be so efficient at it we won't stand a chance.

At least we know to blame Japan when it all happens.
