cannot roslaunch rbx2_bringup pi_robot_with_gripper.launch
Hi everyone. I'm learning ros_by_example step by step. When I have installed the packages required by the book and tried the command roslaunch rbx2_bringup pi_robot_with_gripper.launch sim:=true
there are some mistakes like
ERROR: cannot launch node of type [arbotix_python/arbotix_driver]: arbotix_python
ROS path [0]=/opt/ros/indigo/share/ros
ROS path [1]=/home/shantengfei/catkin_ws/src
ROS path [2]=/opt/ros/indigo/share
ROS path [3]=/opt/ros/indigo/stacks` `ERROR: cannot launch node of type [arbotix_controllers/gripper_controller]: arbotix_controllers
ROS path [0]=/opt/ros/indigo/share/ros
ROS path [1]=/home/shantengfei/catkin_ws/src
ROS path [2]=/opt/ros/indigo/share
ROS path [3]=/opt/ros/indigo/stacks
I tried with the similiar method like this.But it did'nt work.I have put source /home/shantengfei/catkin_ws/devel/setup.bash
in my ~/.bashrc and the ROS_PACKAGES_PATH is /home/shantengfei/catkin_ws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks
.Could someone give me a solution?Thanks.
Well as stated in the answer you found, it means ROS does not find your package, either because it's not installed or because you did not correctly linked it. Did you fixed your other issue, the one for which you asked a question not long ago. it seems to me that this one is linked to the other.
Thanks for your reply. I can find the rbx2 package using roscd/roslaunch, so I think taht this package has be installed.the formmer question is another package that was installed recnetly since I build the workspace I can find the same name folder in ~catkin_ws/build.
The package that isn't found is not rbx2, it is
arbotix_python
, can you look specially for this one and tell me if you have it ?Sorry I didn't install the package.After I installed the package,it works!Thanks!But another problem I asked still unsloved.Could you please give me some suggestion?
