Crashing Drones Into Test Dummies for Safety

Alan Levin for Bloomberg:  Hank sat impassively on a Virginia Tech athletic field, ready to take it on the chin for the future of drone commerce.

About 30 yards away, an eight-rotor unmanned copter hovered, buzzing like a swarm of bees. The 21-pound drone tilted forward, accelerated sharply and slammed into Hank’s head, smacking the crash-test dummy’s neck backward and embedding shards of shattered propeller in his plastic face.

There is little disagreement that the small- and medium-sized drones flooding the U.S. market can seriously injure or even kill someone. Understanding and minimizing the risk will be key to convincing regulators to expand their permitted uses, clearing the way for plans by Amazon.com Inc. and Alphabet Inc. to have them deliver packages or news outlets such as Time Warner Inc.’s CNN to use them for aerial video.  Cont'd...

ST Robotics Develops the Workspace Sentry for Collaborative Robotics

The ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
