In dicey situations, fire-dousing robots or fire-fighting drones can save lives on both land and air.
Now, thanks to a Portuguese startup and its remotely-operated life buoy, those in peril on the sea could expect help to come just as fast.
With a turbine on each side, the U-shaped device has a top speed of 15 km/h and is impervious to rough seas.
The wireless connection allows control within a radius of up to 300 metres and the lithium-ion battery enables continuous coverage of close to 6 kilometres.
Rescue workers can follow their devices’ performance and status in real time via the app.
Meanwhile drones with defibrillators are helpful for heart attack victims in difficult terrain.
