A New Modeling Method of Angle Measurement for Intelligent Ball Joint Based on BP-RBF Algorithm

open access: yesApplied Sciences, 2019
The rotation orientation and the angle of precision of an intelligent ball joint cannot be automatically obtained in passive motion. In this paper, a new method based on a Hall sensor with a permanent magnet (PM) is proposed to identify the spatial ...

A comparison of deformity correction capabilities in hexapod frame systems

open access: yesJournal of Limb Lengthening & Reconstruction, 2016
Context: Hexapod fixators can be divided into two basic design groups. One group consists of frames that use ball and socket joint struts attached to the outer surface of the rings.

Development and Verification of Mechanism for Enhancement of Steering Angle and Active Locomotion for Magnetic Micro Active-Guidewire

open access: yesIEEE Access, 2020
In this study, the authors developed a novel active guidewire including a spiral-type magnetic microrobot and ball joint to realize active locomotion and improve the steering capability within external magnetic fields. Most active guidewires provide only

Using Computer Simulation to Investigate Which Joint Angle Changes Have the Most Effect on Ball Release Speed in Overarm Throwing

open access: yesApplied Sciences, 2019
Efficient throwing mechanics is predicated on a pitcher’s ability to perform a sequence of movements of body segments, which progresses from the legs, pelvis, and trunk to the smaller, distal arm segments.

Generation Mechanism of Linear and Angular Ball Velocity in Baseball Pitching

open access: yesProceedings, 2018
The purpose of this study was to quantify the functional roles of the whole-body’s joint torques including fingers’ joints in the generation of ball speed and spin during baseball fast-ball pitching motion. The dynamic contributions of joint torque term,

Finite and infinitesimal rigidity with polyhedral norms [PDF]

open access: yes, 2014
We characterise finite and infinitesimal rigidity for bar-joint frameworks in R^d with respect to polyhedral norms (i.e. norms with closed unit ball P a convex d-dimensional polytope).
