Safety Rotor System Keeps Fingers Safe

Jun-01-18 A low-cost Safety Rotor sensor from the University of Queensland halts drone propellers if a finger gets too close to the blades.

The twenty-dollar sensor was developed for use with the more powerful quadcopter drones, and consists of a hoop that spins slowly around the propellers. When an object hits the hoop, causing it to slow, optical sensors detect the hoop speed and trigger the ‘special electro-dynamic braking technique’ to slow and stop the blades very quickly.

According to the team, the safety hoop adds little extra weight and does not alter the endurance or maneuverability of the drone.
