Not All Industrial Gyros Meet the Challenges of Precision Agriculture

MEMS gyroscopes have found their way into a wide range of industrial applications. These industrial-grade MEMS sensors differ from consumer-grade devices in that they can accurately perform in harsh conditions characterized by extreme temperature ranges with constant shocks and vibrations. Industrial applications include platform stabilization in land, air, sea, and space navigation systems, precision agriculture, precision robots, unmanned aerial (UAV) and nautical vehicles, construction equipment, offshore drilling, to name just a few. The needs of industrial applications differ from consumer [...]

What Makes Video Drones So Nimble?

If you have watched broadcasted outdoor sports events recently, then you may have noticed small, spider-like video drones hovering above the athletes. These unmanned helicopters, used for aerial filming, are remarkably maneuverable. They allow media outlets to move in closer to the action, and follow it more smoothly than a camera mounted on a crane or on a conventional helicopter. What makes these video drones so nimble is a sophisticated system for motion control and stabilization, called an attitude and [...]

Sound Waves Killed the Drone

Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have discovered an easy and efficient way to take out drones – sound. Every drone makes use of a gyroscope to track its orientation and tilt, which allows it to make movements and remain stable while in the air. If that gyroscope is deactivated, however, the drone cannot remain in the air for long. In their study, KAIST scientists were able to target the on-board MEMS gyroscope using very [...]
