Elbow and knee joint for hard space suits [PDF]
, 1986 An elbow or knee joint for a hard space suit or similar usage is formed of three serially connected rigid sections which have truncated spherical configurations. The ends of each section form solid geometric angles, and the sections are interconnected by

A Bio-Inspired Tensegrity Manipulator with Multi-DOF, Structurally Compliant Joints
, 2016 Most traditional robotic mechanisms feature inelastic joints that are unable to robustly handle large deformations and off-axis moments. As a result, the applied loads are transferred rigidly throughout the entire structure.

Estimating Upper Extremity Joint Contributions in Functional Motions to Create a Metric for Injury Prevention Using OpenSim [PDF]
, 2014 Functional movements have the potential to predict risk of injury based on the frequency of these movements on a daily basis. In order for a metric to be established, a variety of healthy subjects must be recorded performing these motions.

Spring and Power in Hovering Ornithopters
Advanced Intelligent Systems, EarlyView.Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...
