|                 | |       | the mechanism has lost one-degree-of freedom in this position).
|                 | |       | Try first to use another Modelica.Mechanics.MultiBody.Joints.Assemblies.JointXXX component.
|                 | |       | In most cases it is best that the joints outside of the JointXXX
|                 | |       | component are revolute and NOT prismatic joints. If this also
|                 | |       | lead to singular positions, it could be that this kinematic loop
|                 | |       | cannot be solved analytically. In this case you have to build
|                 | |       | up the loop with basic joints (NO aggregation JointXXX components)
|                 | |       | and rely on dynamic state selection, i.e., during simulation
|                 | |       | the states will be dynamically selected in such a way that in no
|                 | |       | position a degree of freedom is lost.
