Detailed Description

Joint waypoint motion.

This motion follows multiple joint waypoints in a time-optimal way.

Constructor & Destructor Documentation

◆ JointWaypointMotion()

franky::JointWaypointMotion::JointWaypointMotion	(	const std::vector< PositionWaypoint< JointState > > &	waypoints,
		const RelativeDynamicsFactor &	relative_dynamics_factor = `1.0`,
		bool	return_when_finished = `true`
	)

explicit

Parameters

waypoints	Joint waypoints to follow.
relative_dynamics_factor	The relative dynamics factor for this motion. The factor will get multiplied with the robot's global dynamics factor to get the actual dynamics factor for this motion.
return_when_finished	Whether to end the motion when the last waypoint is reached or keep holding the last target.
