A pneumatic muscle hand therapy device

The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
Intensive repetitive therapy improves function and quality of life for stroke patients. Intense therapies to overcome upper extremity impairment are beneficial, however, they are expensive because, in part, they rely on individualized interaction between the patient and rehabilitation specialist.

APAM: Antagonistic Pneumatic Artificial Muscle

2018 IEEE International Conference on Robotics and Automation (ICRA), 2018
We present a pneumatic actuator capable of changing length by 1000%, applying both pushing and pulling forces, and independently modulating its length and stiffness. These characteristics are enabled by individually addressable internal and external chambers that work antagonistically against one another.

Manipulators Driven by Pneumatic Muscles

2006
In recent years more and more publications reporting alternative actuators, including artificial muscles, for climbing and walking robots have appeared in the literature. This paper considers pneumatic artificial muscles, better known as McKibben muscles and fluidic muscles, the so called FESTO actuators. The dynamic and static characteristics of these

Thermo-Pneumatic Artificial Muscle: Air-Based Thermo-Pneumatic Artificial Muscles for Pumpless Pneumatic Actuation

Soft Robotics
To make robots more human-like and safer to use around humans, artificial muscles exhibiting compliance have gained significant attention from researchers. However, despite having excellent performance, pneumatic artificial muscles (PAMs) have failed to gain significant traction in commercial mobile applications due to their requirement to be tethered ...

Adaptive Servomechanism of Pneumatic Muscle Actuators With Uncertainties

IEEE Transactions on Industrial Electronics, 2017
Precise control of a pneumatic muscle actuator is a challenging problem, due to its nonlinear and time-varying characteristics. Specifically, it can be modeled as parallel connection of a nonlinear friction force, a nonlinear spring, and a nonlinear contractile element.

A chemo-pneumatic drive source for flexible operation of pneumatic muscle actuators

Proceedings of IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS'94), 2002
Hydraulic, pneumatic and electrical systems form the principle power sources that have been used to operate robots in industrial environments. However, when considering the needs of advanced robotics, one of the most fundamental requirements and problems is the provision of a suitable energy source to power the robot in a nonindustrial, often remote ...

Pneumatic Air Muscle and Pneumatic sources for light weight autonomous robots

2011 IEEE International Conference on Robotics and Automation, 2011
Faced with the challenge of making running speed robots, improved light weight actuation is a primary concern. Pneumatic Air Muscle (PAM) has not been advanced significantly since their conception and some new features are needed to meet compact bi-pedal robots.

Transforming insect electromyograms into pneumatic muscle control

SPIE Proceedings, 2006
Biological inspiration has a history of advancing the field of robotics. Increasingly, robots are also being used in the modeling of biological systems. In this paper, we use recorded cockroach electromyograms (EMGs) to drive artificial muscle (braided pneumatic actuator) activation and thereby robot joint motion, in an effort to model the ...

Braided Pneumatic Muscle Actuators

IFAC Proceedings Volumes, 1993
Abstract This paper considers the requirements for a flexible actuation system that can be applied to untethered robots. Using organic muscle specifications as a base, mathematical models of the drive forces and operating principles in a braided pneumatic actuator are studied.

Isotonic characteristics of a pneumatic muscle actuator

Advanced Robotics, 2014
The article presents the problems of determination of the static characteristics of the pneumatic muscle actuator for an artificial hand. The procedure of experimental investigation of the constant load characteristics (the so called isotonic characteristics) of the muscle is described.
