The paper studies gyroscopic obstacle avoidance for autonomous vehicles. The goal is to obtain a simple controller that steers around obstacles and stabilizes to a desired state. The approach is applicable under the assumption that the obstacles are convex and that the control inputs can generate the required steering forces. This work extends the existing gyroscopic obstacle avoidance methodol...

We study the phenomenon of gyroscopic precession and the analogues of inertial forces within the framework of general relativity. Covariant connections between the two are established for circular orbits in stationary spacetimes with axial symmetry. Specializing to static spacetimes, we prove that gyroscopic precession and centrifugal force both reverse at the photon orbits. Simultaneous non-re...

The standard relation between the field momentum and the force is generalized for the system with a field singularity: in addition to the regular force, there appears the singular one. This approach is applied to the description of the gyroscopic dynamics of the classical field with topological defects. The collective– variable Lagrangian description is considered for gyroscopical systems takin...

In 1890 Bryan observed that when a vibrating structure is rotated the vibrating pattern rotates at a rate proportional to the rate of rotation. During investigations of the effect in various solid and fluid-filled objects of various shapes, an interesting commonality was found in connection with the gyroscopic effects of the rotating object. The effect has also been discussed in connection with...

A new micro gyroscope based on the surface acoustic wave (SAW) gyroscopic effect was developed. The SAW gyroscopic effect is investigated by applying the surface effective permittivity method in the regime of small ratios of the rotation velocity and the frequency of the SAW. The theoretical analysis indicates that the larger velocity shift was observed from the rotated X-112°Y LiTaO3 substrate...

In this paper energy method is used to calculate rotor response with loose rotating disk on it. System equation of motion is obtained based on energy method and Lagrange equation. Mathematical modeling of loose disk in a rotor bearing system has resulted in terms similar to unbalance and gyroscopic effect in the system equation of motion. The effect of loose disk axial position and orthotropic ...

Wearable projectors have been extensively studied with a focus on miniaturization. However, stabilization of the projected images is critical, for otherwise the information cannot be read when the user walks or runs. This paper introduces two methods of stabilization for images projected on the user’s hand: optical stabilization and gyroscopic stabilization. We conducted an experiment to quanti...

A mechanism has been proposed that utilizes the gyroscopic moment generated by tilting rotation axis of a flywheel for stabilization control unstable system. In this study, we investigate effectiveness feedback which drives gimbal to maintain standing posture an structure such as two-wheel vehicle. Although simple angle enables keep standing, both and continue shaking little little. This is bec...
