Detailed Description

Joint Trajectory Point used to describe a joint goal for a robot trajectory.

Background: The TOOL is something held by the robot. It is located relative to robot wrist/tool plate. The WOBJ is something that exists in the world/global environment that is not held by robot.

For a JointTrajectoryPt, the transform from wrist to tool, and base to workobject, are defined by fixed frames. These transforms are important when calculating interpolation. The joint position is specified as a nominal with upper/lower tolerances.

The get*Pose() methods of JointTrajectoryPt try to set joint positions of a robot such that tool_ is coincident with wobj_.
