The future of robot armies is here – and it's not what you think

The future of robot armies is here - and it's not what you think Robots are becoming more a part of our lives every year, and worries about a robot army rising up have long plagued the technology. The robot army that saves the world won't be anything like what you imagine. Nope, they aren't little humanoids who can do synchronised martial arts like the ones who dazzled audiences during New Year's festivities in China . And they won't help you find a can of Coke with embarrassing slowness like the man-shaped beast known as Optimus from Elon Musk's Tesla Inc. Instead, they will be microscopic, and mostly made of algae, bacteria and other single-celled organisms.
