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_link
Link

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)
