The Terminator might be running California, but that's about as close as a cyborg has got to taking over the world so far. But even if the robotic revolution isn't here yet, it's gathering pace, according to the annual 'state of the nation' review from the brainiacs at the International Federation of Robotics.
As you can see from this graph - taken from our friends at IEEE Spectrum - some robots are the industrial sort, but the vast majority are deemed to work in 'service'. That includes huggable toys and military machines.
They've just published the latest edition of World Robotics, which shows the trends in robotics and states that there are now more than 6.5 million bots in operation all around the world... with hardware spending for 2007 coming in at a whopping $6bn.
