Prismatic
Prismatic joint (1 translational degree-of-freedom, 2 potential states, optional axis flange)
CONNECTORS
| Name | Type | Description | |
|---|---|---|---|
 | frame_a | Frame_a | Coordinate system fixed to the joint with one cut-force and cut-torque |
 | frame_b | Frame_b | Coordinate system fixed to the joint with one cut-force and cut-torque |
 | axis | Flange_a | 1-dim. translational flange that drives the joint |
 | support | Flange_b | 1-dim. translational flange of the drive drive support (assumed to be fixed in the world frame, NOT in the joint) |
