SUMMARY
The discussion centers on determining the number of linearly independent motions in a mechanical system involving joints J1, J2, and J3. The consensus is that J1 and J3 contribute to the system's motion, while J2's contribution may be considered irrelevant due to the global motion constraint. Specifically, the analysis indicates that fixing one rotation simplifies the evaluation of independent motions, leading to a clearer understanding of the system's degrees of freedom.
