Two Way Radio for Drones Means Rescuers Can Hear a Cry for Help

A rescue drone can be used to find you, but what if you could talk back to the rescue drone? Dotterel Technologies has a 2-way radio solution that could aid in search and rescue. This would allow a conversation with the person being searched for, or even the ability to listen for a cry for help to locate someone. A highly directional microphone array and real-time processor make this possible.

How bees and drones team up to find landmines

Old landmines are a serious problem in some areas of the world. According to Landmine Monitor, 6,897 people were killed or injured by mines and explosive remnants of war in 2018. There are an estimated 80,000 landmines in Bosnia and Herzegovina and about 30,000 in Croatia.

The mines are difficult to find, however, bees can be trained to detect the scent of the explosives with their antennae. Now a team from Bosnia and Herzegovina and Croatia have found a way to use drones to capture video of the bees that can be analyzed to indicate where landmines may be hidden in the ground.

New UC telehealth drone makes house calls

Telehealth has grown tremendously during the pandemic. But not everybody has the Internet. Now four Inventors from three colleges at the University of Cincinnati have collaborated to develop a semi-autonomous prototype drone that can be sent to people’s homes. The small quadcopters use navigational algorithms developed by UC engineers to maneuver inside a home.

Control System Helps Several Drones Team Up to Deliver Heavy Packages

A Georgia Tech Indoor Flight Lab is using multiple drones to lift a heavy package. A control algorithm directs a team of small drones. They measure thrust and altitude to estimate the weight of the package and could even be sent to your location to pick up a large package. The demonstration used four drones, but the control algorithm isn’t limited to that number. This solution might be better than a fleet of drones of different sizes and lift capacity. In many ways, controlling a group of connected drones is more difficult than controlling a swarm of robots that fly independently.

Sheriff drones can now deliver lifejackets during water rescues

The San Mateo County Sheriff’s office announced they can deliver lifejackets to swimmers in need. A small quadcopter carries the lifejacket on a short tether and a button on the controller lets the officer drop the life jacket. The drone remains in the air some distance above the swimmer. This is part of their Water Safety Campaign. Video on Instagram.
