Hybrid Force Control Based on ICMAC for an Astronaut Rehabilitative Training Robot

International Journal of Advanced Robotic Systems, 2012
A novel Astronaut Rehabilitative Training Robot (ART) based on a cable-driven mechanism is represented in this paper. ART, a typical passive force servo system, can help astronauts to bench press in a microgravity environment.

Design and Control of a Cable-Driven Exoskeleton System for Upper-Extremity Rehabilitation

IEEE Access
Stroke rehabilitation with the assistance of exoskeleton robots has the potential to facilitate the recovery of motor skills by guiding, supporting, and encouraging movement in the affected limbs. In this work, an upper-extremity exoskeleton actuated by the cable transmission mechanism, was developed for rehabilitation training of stroke patients.

Hawaii Deep Water Cable (HDWC) Program : cable overloadability study

, 1986
The scope of this study is to determine the short term overload capability of Cable No. 116 in the event of the loss of one pole of the dc transmission system. Such a loss would result in the loss of 250 MW of transmitted power. This exceeds the spinning

Partial discharge on-line monitoring for HV cable systems using electro-optic modulators

, 2004
A technique for the remote inspection and monitoring of partial discharge (PD) activity using an optical network is described. The network uses a LiNbO3 modulator to modulate the intensity of the transmitted laser light approximately proportional to the ...

Mechanical Design and Kinematic Modeling of a Cable-Driven Arm Exoskeleton Incorporating Inaccurate Human Limb Anthropomorphic Parameters

Sensors, 2019
Compared with conventional exoskeletons with rigid links, cable-driven upper-limb exoskeletons are light weight and have simple structures. However, cable-driven exoskeletons rely heavily on the human skeletal system for support.
