bool generic_control_toolbox::KDLManager::addSegment	(	const std::string &	end_effector_link,
		KDL::Segment &	new_segment
	)

Adds a new segment at the end of the requested chain. WARNING: The intended use case is to facilitate dynamic computations when the robot has a load that is not included in the chain's definition, e.g., a complex gripper. KDL does not support removing segments, so this should not be used to set a variable load.

new_segment	A new segment to be added at the end of a chain.
