Orientation Control System: Enhancing Aerial Maneuvers for Quadruped Robots [PDF]
Sensors, 2023 For legged robots, aerial motions are the only option to overpass obstacles that cannot be circumvented with standard locomotion gaits. In these cases, the robot must perform a leap to either jump onto the obstacle or fly over it.

Research on the Accumulative Damage of Flywheels Due to In-Space Charging Effects
AerospaceHigh-speed rotating flywheel bearings, designed for space applications, generate a high-resistance hydrodynamic lubrication film, which isolates the rotor, transforming it into a conductor. This phenomenon introduces a novel failure mode—flywheel bearing

Flywheels in renewable energy systems: a review of recent developments and future directions [PDF]
, 2023 . Flywheels, an age-old mechanical device, serve to stabilize power output by counteracting fluctuations in rotational speed through their inertia. They find widespread use in various applications such as internal combustion engines and industrial ...

Physical Review A, 2016 A quantum flywheel is studied with the purpose of storing useful work in quantum levels, while additional power is extracted continuously from the device. The flywheel gains its energy form a quantum heat engine. Generally, when a work repository is quantized the work exchange with the engine is accompanied with heat exchange, which may degrade the ...
