Maybe this is a result of my configuration choices, but why does the planner never do an initial in-place rotation? It is happy to do an in-place rotation at the end of a move.

No, sorry. And I haven't looked at it in quite a while.

Thanks. I don't have this set up any more, but will try that when I do.

Unfortunately no.

With Unbuntu 14.04 and Indigo, I cloned the pointgrey_camera_driver to catkinws/src and did catkin_make install. When I:

roslaunch pointgrey_camera_driver camera.launch

if I

rostopic echo /camera/image_color

the camera_nodelet_manager process dies. I don't know where the problem might be. This did work at one time. Also FlyCapture works.

With Indigo and Ubuntu 14.04 I would like to control the parameters of a BlackFly GiGE camera using pointgrey_image_driver. I can see the image using image_view while running the driver.

It looks like the parameters should be accessible using dynamic reconfigure but when I publish messages from the command line, there is no effect on the image. Examples of messages I have tried:

rostopic pub -1 /camera/camera_nodelet/parameter_updates dynamic_reconfigure/BoolParameter '{name: auto_white_balance, value: False}'

rostopic pub -1 /camera/camera_nodelet/parameter_updates dynamic_reconfigure/BoolParameter '{name: white_balance_red, value: 3}'

Actually, I'd just like to set all the parameters once so if there's a way to do that other than by using dynamic_reconfigure, that would be great to know.

When I look at the parameter_updates topic, I see that there are no subscribers to that topic. That seems like a problem.

For general navigation, I'm using move_base. There are times when I would like to control my motion controller (Galil) directly by sending it position commands. Is the way to do this to write my own action server and send goals to that instead of the move_base server? If that's right, are there any Python examples around?

I'd like to prevent the local planner from using laser data, but I still want to publish it so that I can process it elsewhere. How can I do that?

This is resolved. It was a bug in the indigo branch of the fake_localization node of the example I was trying. Now it works as I expected it should.

Where do I set the size of the global map?

I want to move use move_base to travel distances in the vicinity of 35m. Increasing the size of the local window so that it is large enough causes the update rate of the cost map to fall too low. I would like to keep a reasonable local costmap window (e.g., 6m x 6m) but still be able to set a larger global goal. Is this possible?

I am using a blank map and setting the initialpose by publishing to the initialpose topic. I expected that rViz would subscribe to this and that the initial pose in rViz would reflect it. But publishing different initial pose's does not change the initial location of my robot in rViz. Why is that?

I guess I don't understand how rViz should respond to initialpose messages. I run the rbx1 fake_nav_test and either manually in rViz or use rqt_publisher to send an initialpose message. I expect the robot to jump to the initial pose on the rViz screen, but nothing happens. This is all in the map reference frame.

I am using an example from ROS By Example Volume 1. The files are here: https://github.com/pirobot/rbx1 and I am using rbx1/rbx1_nav/launch/fake_nav_test.launch. I run roslaunch rbx1_nav fake_nav_test.launch.
