The smaller and lighter electronics get, the more ways they can be used. A team of researchers has come up with a compact radar system the size of a matchbox that could be deployed in drones, guidance systems for people with vision problems, and other gadgets where portability and low cost are important.
The largest drone delivery network in the world has been launched in Ghana, which experts say will save lives and transform the developing nation’s healthcare sector.
The drone network is set to deliver blood, essential medicines and vaccinations across the middle-income, West African country.
Speaking about the official launch of the service on April 24, Ghana’s President Nana Addo Dankwa Akufo-Addo said it was part of a drive to ensure universal access to lifesaving medicine in Ghana.
Origami-based structures have been used to create deployable solar arrays for space, adaptable acoustic systems for symphony halls and even crash protection systems for flying drones.
Now researchers at the Georgia Institute of Technology have created a new type of origami that can morph from one pattern into a different one, or even a hybrid of two patterns, instantly altering many of its structural characteristics.
The research, which was supported by the National Science Foundation and is to be published April 19 in the journal Physical Review Letters, could unlock new types of origami-based structures or metamaterials that leverage the characteristics of two types of origami.
We’ve seen autonomous aircraft doing everything from spraying crops to surveying wildlife, and now the Swiss air rescue organization Rega has announced a drone that’s capable of searching for and finding missing people all on its own.
The following is a guest post by talented author and self-described nerd Ryan LaDue.
The Latest Wave of Sensor Tech Could be a Game-Changer for LiDAR-Equipped UAVs
Avalanche photodiode sensors are semiconductors capable of converting photons into electrons with an extremely high level of precision. The technology isn’t as new as you might think, but accessible units used for laser range finders (as part of LiDAR systems) have only been making their way into consumer markets in recent years.
