For the first time, the Laboratory for Autonomous Flying Robots (awesome, I know) at the Berlin Institute of Technology has used three autonomous helicopters to transport a load together, cooperating without any human intervention. It's a big step forward for collaborative robots, which many experts believe is the wave of the future.
Think of it: an army of robots working together to construct a building, not requiring human intervention after being given the plans. They'd know when they were needed and would communicate as to which robot needed to perform what tasks. It's pretty fascinating stuff, albeit fascinating stuff that might just eliminate a bunch of jobs from people. But hey, you can't stop progress, right?
