RobotModel.add_joint

RobotModel.add_joint(name, type, parent_link, child_link, origin=None, axis=None, limit=None, **kwargs)[source]

Adds a joint to the robot model.

Provides an easy way to programmatically add a joint to the robot model.

Parameters:

namestr: The name of the joint
typeint: The joint type, e.g. Joint.REVOLUTE
parent_linkLink: The joint’s parent link.
child_linkLink: The joint’s child link.
originFrame: The joint’s origin frame.
axisVector: The joint’s axis.
limitlist of 2 float: The lower and upper limits of the joint (used for joint types Joint.REVOLUTE or Joint.PRISMATIC)
**kwargsdict[str, Any], optional: The keyword arguments (kwargs) collected in a dict. These allow using non-standard attributes absent in the URDF specification.

Joint: The created Joint

Raises:

ValueError: If the joint name is already used in the chain.

Examples

>>> from compas.geometry import Frame
>>> robot = RobotModel("robot")
>>> parent_link = robot.add_link("link0")
>>> child_link = robot.add_link("link1")
>>> origin = Frame.worldXY()
>>> axis = (1, 0, 0)
>>> j = robot.add_joint("joint1", Joint.CONTINUOUS, parent_link, child_link, origin, axis)
