Robot Arm Safety Improvement by Position/Torque Switching Control

2011
With the development of robot technology, it is an inevitable trend in the future that Robots will come into the normal life. Robots must be safe enough and ensure no hazard to person in order to coexist with people harmoniously. This paper provides a method to promote the robot safety by taking position-torque-position switching control. Namely, robot

Electromyographic response to pseudo-random torque disturbances of human forearm position

Neuroscience, 1978
Abstract Pseudo-random torque disturbances applied to the human forearm permitted the identification of linear relationships between motion and biceps/triceps electromyographic activity. In particular, a weighted sum of position, velocity and acceleration provided an adequate description of electromyographic activity over a large range of disturbance

Position and torque control via rehabilitation robot and functional electrical stimulation

2017 International Conference on Rehabilitation Robotics (ICORR), 2017
Two common rehabilitation therapies for individuals possessing neurological conditions are functional electrical stimulation (FES) and robotic assistance. This paper focuses on combining the two rehabilitation strategies for use on the biceps brachii muscle group.

Quadriceps Femoris Torque and EMG Activity in Seated versus Supine Position

Medicine & Science in Sports & Exercise, 2003
To compare voluntary and electrically evoked knee extensor torque, surface electromyography (EMG), and activation level obtained under seated versus supine position, i.e., with shortened versus lengthened rectus femoris (RF) muscle.The knee extensor torque obtained during maximal voluntary contractions (MVC) and after single and paired stimuli applied ...

Robot Position Optimization Based on Joint Mean Torque Norm

2017
Optimal plant-floor robot positioning is a non-trivial task for robotic manufacturing. An unsuitable robot positioning may cost time and energy, which after thousands of cycles may be significant. The present article presents an approach to choose the robot base position through a numerical optimization tool.

APPLICATION OF AIR TORQUE POSITION DAMPERS FOR AIRFLOW MEASUREMENT

Proceedings
The subject of the paper is a damper, which is referred to as ATP (Air Torque Position) based on its mode of operation. The ATP damper indirectly measures air velocity by assessing the torque applied to the blades and their position. The airflow rate is determined by multiplying the air velocity with the cross-sectional area of the damper.
