US startup unveils tech to turn normal helicopters self-driving

US-based autonomous helicopter startup Skyryse unveiled technology which could potentially turn normal helicopters into self-driving ones, through a modified FAA-approved helicopter 'Luna'. Called the "Skyryse Flight Stack", the system could enable future fleets of air taxis to fly themselves over cities, the startup claimed. It also includes sensor pads on the ground, called "smart helipads".
