### Planning to a joint-space goal
### ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
###
### Let's set a joint space goal and move towards it.
### First, we will clear the pose target we had just set.
#group.clear_pose_targets()
### Then, we will get the current set of joint values for the group
#group_variable_values = group.get_current_joint_values()
#print "============ Joint values: ", group_variable_values
### Now, let's modify one of the joints, plan to the new joint
### space goal and visualize the plan
#group_variable_values[0] = 1.0
#group.set_joint_value_target(group_variable_values)
#plan2 = group.plan()
#print "============ Waiting while RVIZ displays plan2..."
#rospy.sleep(5)
### Cartesian Paths
### ^^^^^^^^^^^^^^^
### You can plan a cartesian path directly by specifying a list of waypoints
### for the end-effector to go through.
#waypoints = []
## start with the current pose
#waypoints.append(group.get_current_pose().pose)
## first orient gripper and move forward (+x)
#wpose = geometry_msgs.msg.Pose()
#wpose.orientation.w = 1.0
#wpose.position.x = waypoints[0].position.x + 0.1
#wpose.position.y = waypoints[0].position.y
#wpose.position.z = waypoints[0].position.z
#waypoints.append(copy.deepcopy(wpose))
## second move down
#wpose.position.z -= 0.10
#waypoints.append(copy.deepcopy(wpose))
## third move to the side
#wpose.position.y += 0.05
#waypoints.append(copy.deepcopy(wpose))
### We want the cartesian path to be interpolated at a resolution of 1 cm
### which is why we will specify 0.01 as the eef_step in cartesian
### translation. We will specify the jump threshold as 0.0, effectively
### disabling it.

#waypoints, # waypoints to follow

#print "============ Waiting while RVIZ displays plan3..."
#rospy.sleep(5)
### Adding/Removing Objects and Attaching/Detaching Objects
### ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
### First, we will define the collision object message
#collision_object = moveit_msgs.msg.CollisionObject()
### When finished shut down moveit_commander.
