@Pi Robot, previous problem solved. Had to check one by one and use normal pi_tracker instead of the one I adapted on skeleton_markers. Launch file skeleton.launch on pi_tracker for should be finding openni_launch. I also have another question, are you using forward or inverse kinematics?

Been changed, still not working. Changed them in the groovy-rosbuild file and is working, but not with the catkin, still gibing "0.0"

Hi @Pi Robot, I sent you an email yesterday. However, I realized I do not need the dynamixel motor with my robot (Baxter Robot) but when I do a "rostopic echo /joint_states" all the positions are "0.0" when entering the TELEOPJOINTS mode. You know why could that be? Because the rosbuild was doing ok

skeleton.launch is working properly. Changed everything to my URDF, now when I try tracker.launch I get the following error.... from dynamixel_controllers.srv import TorqueEnable, SetTorqueLimit, SetSpeed ImportError: No module named dynamixel_controllers.srv I don't understand this. THank you

Param xml is "param command="$(find xacro)/xacro.py '$(find pi_tracker)/urdf/pi_robot/pi_robot_with_two_arms.xacro'" name="robot_description"/

Invalid tag: Cannot load command parameter [robot_description]: command [/opt/ros/groovy/stacks/xacro/xacro.py '/home/alonso/DissertationMorenoGroovy/src/pi_tracker/urdf/pi_robot/pi_robot_with_two_arms.xacro'] returned with code [1]. Param xml is "param command="$(find xacro)/xacro.py '$(find pi_tracker)/urdf/pi_robot/pi_robot_with_two_arms.xacro'" name="robot_description"/

Yes I did and I am not getting that error anymore, I realized that I had to "run" my robot's bash before, but now I am getting another error when doing "roslaunch pi_tracker skeleton.launch" (I should mention I am using groovy)

alonso@cseebaxter:~/DissertationMorenoGroovy/src$ roslaunch pi_tracker skeleton.launch [skeleton.launch] is neither a launch file in package [pi_tracker] nor is [pi_tracker] a launch file name This is what I got and the pi_tracker is located as follows alonso@cseebaxter:~/DissertationMorenoGroovy/src/pi_tracker$

Hi I am using pi_tracker with catkin, I saved the package inside src and the catkin_make. When I try to launch skeleton.launch it says it is not a launch file. Does anyone know how to fix this problem?

Hey I am using the skeleton_markers package and is working great, but I need the data published by markers_from_tf .... is it only a tf listener? Thank you

Hi I am really new with ROS, what I want to do is track the skeleton using openni_tracker with groovy which is already working but I need to get the data from the joints (position) and I can see it with rostopic echo /tf, but my I have some questions.
1.- How can I actually interpret the output values?
2.- The openni_tracker is path is "opt/ros/groovy/stacks/openni_tracker" and I do not know how to write a subscriber to the transforms, I saw the tutorial but did not help much
3.- Is there any way I can put the openni tracker inside my own workspace? because I tried several things but it kept thrwoing errors during the rosmake

Any help will be much appreciated
