ERROR  : solver: DASSL: failed step at t = 0.147270: 
Singular position of loop (either no or two analytic solutions;
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.
