Robot football is an actual sport organised by the federation of international robot soccer organisation. It’s aims are to produce a team of robots capable of beating humans by the year 2050. The robots range from 5.5 cm to 150 cm. I like to think that if ever robots did try to take over the world a good way to stop this would be to limit their size to that smaller than a house cat. We can only hope that they don’t then learn how to harness cats and ride them into battle.
