One of the strangest things about human nature is our tendency toward inertia. We take so much uncontrollable change in stride, but when our man-made constructs stop making sense, we’re suddenly stuck in our ways — for instance, the way we measure things in the US, or define daytime throughout …read more

Reaction Wheels Almost Control This Unusual Drone

When you think about all the forces that have to be balanced to keep a drone stable, it’s a wonder that the contraptions stay in the air at all. And when the only option for producing those forces is blowing around more or less air it’s natural to start looking for other, perhaps better ways to achieve flight control.

Taking a cue from the spacecraft industry, [Tom Stanton] decided to explore reaction wheels for controlling drones. The idea is simple – put a pair of relatively massive motorized wheels at right angles to each other on a drone, and use …read more
