Prismatic

Prismatic joint (1 translational degree-of-freedom, 2 potential states, optional axis flange)

Information
CONNECTORS
CLOSE ALL
NameTypeDescription
frame_aFrame_aCoordinate system fixed to the joint with one cut-force and cut-torque
frame_bFrame_bCoordinate system fixed to the joint with one cut-force and cut-torque
axisFlange_a1-dim. translational flange that drives the joint
supportFlange_b1-dim. translational flange of the drive drive support (assumed to be fixed in the world frame, NOT in the joint)
