Are you working with USB2Dynamixel dongle? (you can check the device settings:

$ls -al /dev/ttyUSB0

Can you still control them in Window$? I had twice the problem that the ID's were flipped and I had to reset them. Can you still read out the ID's in the Dynamixel program?

The first "temp" publisher is wrong. It says the robot does never move in the map. Remove it totally.

The corresponding tf chain from map->odom->base_link should be produced by odometry and SLAM/localization, not a static_transform_publisher.

Mercurial is pretty straightforward, as an example:

hg clone https://kforge.ros.org/openni/openni_ros

You can always grab the latest version with:

hg pull
hg update

And you can see other branches with the "branches" command:

hg branches

For anything more than that, I would suggest the Mercurial Quickstart

here are the transforms in the launch file that i got from the dukedusty2 tutorial

there seems to be no link between map and odometry and odometry and base_link

<node pkg="tf" type="static_transform_publisher" name="temp" args="0 0 0 0 0 0 1 map base_link 50"/>

<!--Base platform is 13cm off of ground!-->
<node pkg="tf" type="static_transform_publisher" name="ground_static_tf_publisher" args="0 0 0.13 0 0 0 1 base_link base_platform 50"/>

<node pkg="tf" type="static_transform_publisher" name="hokuyo_static_tf_publisher"
    args="0.14 0 0.06 0 0 0 1 base_platform base_scan 50"/>

Out of the blue, the controller_manager from the ax12_controller_core has stopped working. I am simply launching the file from the tutorial, but it says "Pinging motor IDs 1 through 5" then it says "No motors found, aborting." There is nothing wrong with the power or the data cable. We can manually control the servo through program we had in windows. But nothing happens in ubuntu and ROS. Not sure what happened.

this is what is says after i roswtf

i am using http://www.princeton.edu/~ctralie/Projects/DukeDusty2/Tutorial/#navigation

When I try to set an initial pose for 2d navigation RVIZ crashes on me. When I check the tf tree, I see that odom is off to the side and not even connected. /map connects straight to /base_link. What am I doing wrong?

Hey guys,

I'm new to this ROS business and I needed help with TF and URDF. Usually I "svn co" something, but these two packages require me to "hg" the link. I have

"sudo apt-get install mercurial"

the mercurial SCM, but when i try to hg these packages it says

"abort: There is no Mercurial repository here (.hg not found)!"

I don't know where to go from here. Thanks in advance for the help!
