bool	init (RobotState *robot_state)
	initializes the tree object The initializer's most important functionality is to create a vector of joints. This vector is ordered according to the joint's number given by KDL's tree class, which is used by the kdl_parser to create a KDL::Tree from the robot description. This structure is what a KDL tree solver expects. The vector of joints can later be used to read the joints' positions or to send efforts to them. More...
