Therefore, I would not suggest using your proposed solution. ros2_controllers Commonly used and generalized controllers for ros2-control framework that are ready to use with many robots, MoveIt2 and Navigation2. Joint velocities and accelerations are optional. Similarly to the trajectory representation case above, its possible to support new hardware interfaces, or alternative mappings to an already supported interface (eg. JointTrajectoryController::JointTrajectoryController, JointTrajectoryController::command_interface_configuration, JointTrajectoryController::state_interface_configuration, JointTrajectoryController::read_state_from_hardware, JointTrajectoryController::read_state_from_command_interfaces, controller_interface::get_ordered_interfaces, JointTrajectoryController::topic_callback, JointTrajectoryController::goal_received_callback, JointTrajectoryController::goal_cancelled_callback, JointTrajectoryController::goal_accepted_callback, JointTrajectoryController::fill_partial_goal, JointTrajectoryController::sort_to_local_joint_order, JointTrajectoryController::validate_trajectory_point_field, JointTrajectoryController::validate_trajectory_msg, JointTrajectoryController::add_new_trajectory_msg, JointTrajectoryController::preempt_active_goal, JointTrajectoryController::set_hold_position, JointTrajectoryController::contains_interface_type, JointTrajectoryController::resize_joint_trajectory_point.
