Recent experiments performed with a team of nano quadrocoptors developed by the University of Pennsylvania GRASP Lab and KMel Robotics have produced these impressive results.
The team of researchers has worked out how to get them to fly together in intricate patterns, and even squeeze though tight spaces without hitting each other. Each of the nano ‘copters is self-sensing: that means they can accurately position themselves and maintain balance through even the most complex of movements.
The quadrotor mini-copter is so nimble because it’s constantly learning how to move better, demonstrating what’s called LBMPC (Learning Based Model Predictive Control). In English, that means the aircraft knows how and where it’s moving, and can compensate for mistakes the next time around. The copter quickly because spatially self-aware, learning how to take advantage of itself.
