'BeeRotor' drone uses an insect-style eye to navigate tight spaces
Accelerometers have become integral components for many of our favorite gadgets. By measuring acceleration forces, such as gravity or someone's arm waving clumsily back and forth, these sensors can accurately identify a device's angle in relation to the Earth. It's how your smartphone knows when to automatically switch between portrait and landscape orientation. Now, scientists are researching how drones can be built to fly autonomously without the use of accelerometers. It's led to the creation of "BeeRotor," which, as the name implies, takes inspiration from the visual cues and analysis used by winged insects.
