Tightly-Coupled Monocular Visual-Odometric SLAM Using Wheels and a MEMS Gyroscope

IEEE Access, 2019
In this paper, we present a novel tightly coupled probabilistic monocular visual-odometric simultaneous localization and mapping (VOSLAM) algorithm using wheels and a MEMS gyroscope, which can provide accurate, robust, and long-term localization for ...

Physics of Gyroscope’s “Antigravity Effect”

Advances in Mathematical Physics, 2019
The physics of gyroscopic effects are more complex than presented in existing mathematical models. The effects presented by these models do not match the real forces acting on gyroscopic devices.

Friction Reduction for a Rotational Gyroscope with Mechanical Support by Fabrication of a Biomimetic Superhydrophobic Surface on a Ball-Disk Shaped Rotor and the Application of a Water Film Bearing

Micromachines, 2017
Friction between contacting surfaces of metal materials restricts the application of mechanical support in the high-precision inertial device of a rotational gyroscope. Instead, a disk- or ring-shaped rotor is electrostatically or magnetically suspended.

Function of a Fly Motion-Sensitive Neuron Matches Eye Movements during Free Flight [PDF]

, 2005
Sensing is often implicitly assumed to be the passive acquisition of information. However, part of the sensory information is generated actively when animals move.
