Comments to the: “Closed-form dynamic equations of the general Stewart platform through the Newton–Euler approach” and “A Newton–Euler formulation for the inverse dynamics of the Stewart platform manipulator”

Considering the novelty of the method and creativity of the research that is detailed in the two papers [Mechanism and Machine Theory, Vol. 33, No.7, pp. 993–1012, 1998 and Vol. 33, No.8, pp.1135–1152, 1998], we believe that correcting the following errors appearing in these two papers would enhance their valuable contribution to this field of research.
