🚁This sensor stops your quadcopter before it can cut you
The folks at Spectrum have found a truly cool project for quadcopter pilots.
It’s a spinning sensor that will stop the rotors if your finger gets too close to the blades, thereby preventing you – or your kids – from getting cut.
Researchers at the University of Queensland in Brisbane, Australia created so-called Safety Rotor to help prevent accidents with more powerful quadrotor drones.
