Thank you very much Tom. This remap solved one of my issues.

Hi Tom, did you have the chance to have a look to the data? Thanks in advance!

I have just added some samples for the sensors.

Hello, We have a similar problem but we can not solve it with your proposal. Did you find the reason it worked changing

Hello! I got a solution, perhaps it is not the best one but it works.

I added a generic state to the smach state machine:

StateMachine.add('CANCEL', CancelGoal(),  transitions={'cancel_outcome':'cancel_aborted'})

The CancelGoal function implemented consits of publishing an empty goal in the /move_base/cancel topic:

class CancelGoal(smach.State):
  def  __init__(self):
    smach.State.__init__(self, outcomes=['cancel_outcome'])
    self.cancel_pub = rospy.Publisher('move_base/cancel', GoalID, queue_size=10)

  def execute(self, userdata):
     setCancelState(True)
     goalId = GoalID()
     self.cancel_pub.publish(goalId)    
     return 'cancel_outcome'

I hope this helps.

Best regards, Teresa

Hi, I am using the last version of the elevation packing that Peter updated and it works for me. I had the same problem as you before the update. Are you using the last version?

Hello,

I am working with ROS Indigo and Ubuntu 14.04 and I am looking for elavation mapping packages in order to get a elevation map.

I found two packages:

ETH Zurich: https://github.com/ethz-asl/elevation...

Hector: hector_elevation_maping: https://github.com/tu-darmstadt-ros-p...

I have tried the ethz package but I have a core error when I launch the node, and now I am trying the hector elevation mapping package, but I do not find too much documentation about it.

Has anyone any experience working with elevation maps? Any suggestion about the best package to use and any sort of documentation would be grateful.

Thanks in advance,

Teresa

Hello,

I am using smach with a SimpleActionState to send navigation goals to move_base with:

StateMachine.add('GO_TO_DOCKING_ZONE',SimpleActionState('move_base',MoveBaseAction, goal_cb = goal_callback, result_cb=goToDocking_result_cb),transitions = {'succeeded':'IR_MONITOR'})

And I would like to cancel this goal. I know that the way to do that is with cancel_goal function, but I do not how to call it using smach.

Any suggestions?

Best regards,

Teresa
