When it comes to hobby rotorcraft, it almost seems like the more rotors, the better. Quadcopters, hexacopters, and octocopters we’ve seen, and there’s probably a dodecacopter buzzing around out there ...

Since the dawn of the age of the automobile, motorheads have been obsessed with using as few wheels as possible. Not satisfied with the prospect of being incompletely maimed by a motorcycle, the ...

Wobbling on the waves Schematic diagram of the gyroscopic wave energy converter showing the flywheel coupled to an electric generator on a floating platform. (Courtesy: T. Iida, Journal of Fluid ...

Toy gyroscopes can do all kinds of interesting tricks. The most mysterious one, precession, seems to defy gravity. By definition, precession refers to a change in the orientation of the rotational ...

A gyroscope is any rotating body that exhibits two properties: gyroscopic inertia or rigidity in space and precession or the tilting of the axis at right angles to any force tending to alter the plane ...

I do like stabiliser projects - whether Murata unicyclists or self-balancing tightrope walkers - and here's a "Stabiliser Zonai Device". We're talking DC motors and gyroscopic precession... Thanks to ...

The wobble of Earth’s axis is called precession. While most of us are familiar with our planet’s primary motions — rotation and revolution — few are aware of precession. This characteristic is vividly ...
