We’ve previously covered the ambulance drone. Greg Kumparak wrote about its younger brother, the lifeguard drone:

• Project Ryptide is a self-inflating life preserver ring.
• It can attach to most common drones. A lifeguard can then control it using their phone and have it drop the life preserver next to a drowning person.
• The ring will automatically inflate upon contact with water.
• The system will be on kickstarter and is expected to cost about $99 (drone not included).
