Pre-Grasp Manipulation Planning to Secure Space for Power Grasping
IEEE Access, 2021 An object can be gripped firmly through power grasping, in which the gripper fingers and palm are wrapped around the object. However, it is difficult to power-grasp an object if it is placed on a support surface and the grasping point is near the support

Impacts of Rotation Axis and Frequency on Vestibular Perceptual Thresholds.
Multisensory Research, 2022 In an effort to characterize the factors influencing the perception of self-motion rotational cues, vestibular self-motion perceptual thresholds were measured in 14 subjects for rotations in the roll and pitch planes, as well as in the planes aligned ...

Design procedure for a wind-wheel with self-adjusting blade mechanism
Trudy Odesskogo Politehničeskogo Universiteta, 2014 Developed is a wind-wheel design equipped with the self-adjusting blade. The blade is positioned eccentrically to the balance wheel and can freely rotate around its axis. Elaborated is the method of calculating the energy characteristics for a wind-wheel

Cyclic surfaces accompanying non-ruled quadrics of rotation
Омский научный вестник, 2023 The paper considers the shaping of cyclic surfaces based on nonlinear rotation, in which the axis of rotation and the generatrix in the general case are three-dimensional smooth curves. As a tool for shaping surfaces of non-linear rotation, the method of

Twisted Hi-Bi fiber DFB lasers with controllable output polarization [PDF]
, 2012 We demonstrate that single polarization, hi-bi fiber DFB lasers are in general characterized by elliptical state of polarization, due to the in-built fiber birefringence axis rotation.
