Experimental Validation of Change of Volume in Pneumatic Artificial Muscle during Excitation (pp. 1-6)

Miha Pipan
The majority of pneumatic artificial muscles (PAMs) models for calculating generated force with virtual work are good approximations. These models usually do nottake into account the edge deformations of the muscle orthe elastic deformations of the muscle bladder as a function of different internal pressure of the muscle, but only the contraction of the muscle. This paper presents the method that enables us to accurately measure the change in pneumatic muscle volume. Experimental results are compared with the standard Chou model. Also, further improvement of the PAM model is suggested.
