Pars Drone Demonstrator

Here’s how Popular Science first covered the Pars drone in 2013:

The Pars Aerial Rescue Robot is designed to work as a mobile lifesaver dispensary, flying out to those in need and dropping vital flotation aids until better help can be secured. As currently designed, Pars starts with a quadrotor, which makes sense: quadrotors are versatile platforms, beloved by scientists because the machines can do things like test eagle arms and Kinect-based navigation. Quadrotors are also relatively strong. That means Pars wouldn't have any trouble carrying life preservers as well as a sophisticated navigation software and infrared cameras.

Since then, the drone has undergone a series of tests and improvements, moving from concept to prototype to demonstration. Here’s an early test, using an eight-rotor drone, a single inner tube, and a courtyard:

This next video starts off with animation about the drone concept, before cutting to tests with a working model. In one striking trial, the hexarotor reaches a swimmer in 22 seconds, more than a full minute faster than a lifeguard who started at the same time.

The undersides of the hexarotor arms carry LED lights, so at night swimmers can see the drone coming to save them. The video also gives away an important detail: Pars is still remotely piloted by a human.

Future plans for the drone include floating stations with solar panels where several can recharge simultaneously, as well as more advanced features so drones can save lives on their own. With RTS London launched to manufacture these drones, the beaches of the future might just be safer thanks to some friendly robots.
