def	__init__
def	compliant_close_callback
	do a compliant close using the fingertip sensors (stops at the first detected contact and moves the arm so that the contact stays in place)
def	grasp_adjustment_callback
	do a grasp adjustment using the fingertip sensors (tries to move the hand to obtain non-tip and non-edge contacts)
def	init_reactive_grasp
def	reactive_approach_cb
	do a reactive approach using the fingertip sensors (backs up and moves to the side if a fingertip contacts on the way to the grasp)
def	reactive_grasp_cb
def	reactive_lift_cb
	do a reactive lift using the fingertip sensors (uses slip-servoing to exert just enough force to grasp and lift)
def	reactive_place_cb
	do a reactive place using the fingertip sensors and accelerometer (uses slip controller to stop and open when the object hits the table) if slip controller is not running, just goes past the goal with the Cartesian controller

def reactive_grasp_server::ReactiveGraspActionServer::compliant_close_callback	(	self,
		req
	)

Definition at line 322 of file reactive_grasp_server.py.

def reactive_grasp_server::ReactiveGraspActionServer::grasp_adjustment_callback	(	self,
		req
	)

do a grasp adjustment using the fingertip sensors (tries to move the hand to obtain non-tip and non-edge contacts)

Definition at line 332 of file reactive_grasp_server.py.

def reactive_grasp_server::ReactiveGraspActionServer::init_reactive_grasp	(	self,
		goal
	)

pull relevant parts out of the goal for both reactive grasp and approach

Definition at line 191 of file reactive_grasp_server.py.

def reactive_grasp_server::ReactiveGraspActionServer::reactive_approach_cb	(	self,
		goal
	)

do a reactive approach using the fingertip sensors (backs up and moves to the side if a fingertip contacts on the way to the grasp)

Definition at line 218 of file reactive_grasp_server.py.

def reactive_grasp_server::ReactiveGraspActionServer::reactive_grasp_cb	(	self,
		goal
	)

do a reactive grasp using the fingertip sensors
(backs up and moves to the side if a fingertip contacts on the way to the grasp,
closes compliantly, tries approach and grasp again if gripper opening is not within bounds)

Definition at line 142 of file reactive_grasp_server.py.

def reactive_grasp_server::ReactiveGraspActionServer::reactive_lift_cb	(	self,
		goal
	)

do a reactive lift using the fingertip sensors (uses slip-servoing to exert just enough force to grasp and lift)

Definition at line 256 of file reactive_grasp_server.py.

def reactive_grasp_server::ReactiveGraspActionServer::reactive_place_cb	(	self,
		goal
	)

do a reactive place using the fingertip sensors and accelerometer (uses slip controller to stop and open when the object hits the table) if slip controller is not running, just goes past the goal with the Cartesian controller
