We need more information to help you, like "what was the actual error (copy and paste it)", "what commands did you run", things like that.

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$

Did you sourced the setup file from the devel folder after invoking catkin_make?

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)

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"/

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

The skeleton.launch file needs a URDF model of the robot you are using. The default is to load the two-arm version of Pi Robot which you probably do not have. So modify the skeleton.launch file so that the robot_description param points to the actual location of the URDF file for your robot.

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
