Wrist joint assembly [PDF]

open access: yes, 1978
A wrist joint assembly is provided for use with a mechanical manipulator arm for finely positioning an end-effector carried by the wrist joint on the terminal end of the manipulator arm. The wrist joint assembly is pivotable about a first axis to produce

Prediction of the wrist joint position during a postural tremor using neural oscillators and an adaptive controller

open access: yesJournal of Medical Signals and Sensors, 2016
The prediction of the joint angle position, especially during tremor bursts, can be useful for detecting, tracking, and forecasting tremors. Thus, this research proposes a new model for predicting the wrist joint position during rhythmic bursts and inter-
