Detailed Description

Class encapsulated joint trajectory point data. The point data serves as a waypoint along a trajectory and is meant to mirror the JointTrajectoryPoint message.

This point differs from the ROS trajectory point in the following ways:

The joint velocity in an industrial robot standard way (as a single value).
The duration is somewhat different than the ROS timestamp. The timestamp specifies when the move should start, where as the duration is how long the move should take. A big assumption is that a sequence of points is continuously executed. This is generally true of a ROS trajectory but not required.

The byte representation of a joint trajectory point is as follow (in order lowest index to highest). The standard sizes are given, but can change based on type sizes:

member: type size sequence (industrial::shared_types::shared_int) 4 bytes joints (industrial::joint_data) 40 bytes velocity (industrial::shared_types::shared_real) 4 bytes duration (industrial::shared_types::shared_real) 4 bytes
