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

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

The axis of rotation of the ankle joint [PDF]
The Journal of Bone and Joint Surgery. British volume, 1989 The axis of the talo-crural joint was analysed by roentgen stereophotogrammetry in eight healthy volunteers. Examinations were performed at 10 degrees increments of flexion and pronation/supination of the foot as well as medial and lateral rotation of the leg.

Robust estimation of dominant axis of rotation [PDF]
Journal of Biomechanics, 2007 A simple method is developed for robustly estimating a fixed dominant axis of rotation (AoR) of anatomical joints from surface marker data. Previous approaches which assume a model of circular marker trajectories use plane fitting to estimate the direction of the AoR.

Reappearance of change in time of rotation axis with simulation in baseball-type acceleration sensor
Nihon Kikai Gakkai ronbunshu, 2021 We develop an output simulator for a baseball-type acceleration sensor in which one three-axis sensor for low acceleration and three sensors for high acceleration are installed.
