Design and Experiments of Pneumatic Soft Actuators
Robotica, 2021SUMMARYThe soft actuator is made of superelastic material and embedded flexible material. In this paper, a kind of soft tube was designed and used to assemble two kinds of pneumatic soft actuators. The experiment and finite element analysis are used to comprehensively analyze and describe the bending, elongation, and torsion deformation of the soft ...

Dynamics and control of pneumatic actuators
1995 IEEE International Conference on Systems, Man and Cybernetics. Intelligent Systems for the 21st Century, 2002Pneumatic actuators are, with hydraulic and electrical ones, a large class of actuators today in use in industrial or technical domains to satisfy the very broad range of constraints corresponding to the domains of working parameters. In marked difference with the two other classes, these actuators are extremely simple in their structure, with very low

Dynamic analysis of pneumatic actuators
Simulation Practice and Theory, 1999Abstract The paper deals with the dynamic analysis of double acting actuators, both linear and rotary ones. Two different formulations to model a pneumatic circuit, composed of an actuator and a digital valve, are presented. In the first one an air thermodynamic transformation is assumed and the simulation is carried out in the MATLAB-Simulink ...

A force-controlled pneumatic actuator
IEEE Transactions on Robotics and Automation, 1995This paper presents a new pneumatic actuator for applications requiring moderate, but accurate, force control, such as teleoperation masters and robot wrists. The actuator uses voice-coil flapper valves and low-friction cylinders. Its force is controlled by servoing differential pressure. Aspects of valve design, system modeling, controller design, and

A variable-stiffness and healable pneumatic actuator
Materials Horizons, 2023A pneumatic actuator based on variable-stiffness and self-healing polymers shows high load capacity at room temperature but can be actuated pneumatically upon heating. And it can be thermally healed after damaging, thus can prolong its service time.

Teaching System for Pneumatic Actuations
2018 10th International Conference on Electronics, Computers and Artificial Intelligence (ECAI), 2018The paper presents how teaching pneumatic equipment can be used in the educational process. The paper is structured in three parts. In the first part are investigated the elements that are used in the study of pneumatic automatic systems: products of the profile companies, specific publications, related disciplines.

The Pneumatic Biped ?Lucy? Actuated with Pleated Pneumatic Artificial Muscles
Autonomous Robots, 2005This paper reports on the bipedal robot Lucy which is actuated by pleated pneumatic artificial muscles. This novel actuator is very suitable to be used in machines which move by means of legs. Besides its high power to weight ratio the actuator has an adaptable passive behavior, meaning the stiffness of the actuator can be changed on-line.
