Applied Physics Laboratory was used in 2016 for a demonstration in which a paralyzed man was able to "fist-bump" Barack Obama using signals sent from an implanted brain chip. The limb returned sensory feedback from the arm to the wearer's brain. The APL researches and produces unmanned aerial vehicles for the US military. One of its most recent projects is an unmanned aerial swarm that can be controlled by a single operator on the ground.
