The authors would like to correct the content of Table 2 and the text above Table 2 in their article: Modeling the Static Force of a Festo Pneumatic Muscle Actuator: A New Approach and a Comparison to Existing Models (https://www.mdpi.com/2076-0825/6/4/33).
The unit of the correction angle d 0 , given in Table 2 of [1] on page 8, and the text above, is not degree but radian. Therefore, the angle correction is:
  • d 0 = 0.10 rad = 5.7296 for the DMSP-10-250 and
  • d 0 = 0.073 rad = 4.1826 for the DMSP-20-300
such that the correction of Table 2 is given by:
c 0 c 1 c 2 c 3 d 0
DMSP-10-250 74.085 MPa 689.20 MPa / m 1.8370 GPa / m 2 848.79 MPa / m 3 5.73
DMSP-20-300 93.232 MPa 715.29 MPa / m 1.5483 GPa / m 2 502.95 MPa / m 3 4.18
The authors apologize this literal mistake, but emphasize that the content of the article is still correct. The manuscript will be updated and the original will remain online on the article webpage, with a reference to this Erratum.
