"Otherlab has built prototype drones out of cardboard that are designed to airdrop things like medicine, batteries, and communication devices into dangerous or hard-to-reach places"

"The gliders are pre-programmed with their landing destination, then launched from a cargo plane or other aircraft (in tests, one was launched from a bigger drone). A small electronics package then steers each craft to its target. But with no motors and no need of a battery or fuel, they are meant to have as much room as possible for payload."
