Meet the FreeMotionHandling Sphere from Festo: an indoor flying object that can move in any direction to pick up and drop off items. Its handling system has an ultra-light carbon ring with 8 adaptive propellers. The rotatable helium ball in the middle of the ring comes with a gripping mechanism.
As the above video shows, such a flying object can be used to deliver things to people and interact with them safely. Thanks to an indoor GPS and two on-board cameras, the sphere can react to its surroundings. More info is available here. What do you think? Are you impressed?
