Here's an update on what are commonly known as drones -- or what some call "unmanned aerial vehicles".
This week, the Senate Judiciary Committee has been looking into the use of drones in America and how they might affect privacy. The federal government is working on new rules that could expand permits for drones in the coming years.
"There really aren't a lot of laws in place that explain what's allowed with drones in terms of safety and privacy," says Ben Popper, who has been covering this story for the online tech news site The Verge. "So there has been a rush by states and cities to pass legislation often aimed at their own government employees and law enforcement."
Popper says while cities and states can't ban drones -- that power lies with the FAA -- they can restrict their own employees from using them.
