Kinematic constraint for fixing angle between two frame Z axes
This block represents a kinematic constraint for fixing the angle between two frame Z axes. The two constrained frames, base and follower, lose one rotational degree of freedom with respect to each other. The distance between the two frame origins is not affected. Other kinematic constraints, such as those due to joints and model topology, typically remove additional degrees of freedom between the two frames.
The figure shows the constraint angle between two frame Z axes. The frames can translate with respect to each other if at least one translational degree of freedom exists between the two.
Angle constraint type. The default setting is General.
|Parallel||Align base and follower frame +Z axes.|
|Anti-Parallel||Align the base frame +Z axis with the follower frame -Z axis.|
|Perpendicular||Make base and follower frame Z axes mutually orthogonal.|
|General||Maintain base and follower frame Z axes at the specified angle. By definition, angles must fall in the range 0–180°.|
