Quadrotor Safety System Stops Propellers Before You Lose a Finger

With spinning hoops to detect obstacles combined with electromagnetic braking, this quadrotor safety system is both effective and cheap Photo: Evan Ackerman/IEEE Spectrum Quadrotors have a reputation for being both fun and expensive, but it’s not usually obvious how dangerous they can be. While it’s pretty clear from the get-go that it’s in everyone’s best interest to avoid the spinny bits whenever possible, quadrotor safety primarily involves doing little more than trying your level best not to run into people. Not running into people with your drone is generally good advice, but the problems tend to happen when for whatever reason the drone escapes from your control. Maybe it’s your fault, maybe it’s the drone’s fault, but either way, those spinny bits can cause serious damage. Safety-conscious quadrotor pilots have few options for making their drones safer, and none of them are all that great, due either to mediocre effectiveness Continue reading Quadrotor Safety System Stops Propellers Before You Lose a Finger
