catkin build issue

[Sission]

HI! I suffered a catkin build issue:

franks_ros : 0.7.1 libfranka:0.7.0 franka_ros_interface: master

It is weird because I found "NE_T_EE" in the msg folder. However, I still got the following error. Could you help?

error: ‘struct franka::RobotState’ has no member named ‘NE_T_EE’; did you mean ‘O_T_EE’? static_assert(sizeof(robotstate.NE_T_EE) == sizeof(robotstate.O_T_EE), ^~~ O_T_EE /home/airlab/catkin_ws/src/franka_ros_interface/franka_interface/src/robot_state_controller.cpp:369:63: error: ‘struct franka::RobotState’ has no member named ‘F_T_NE’; did you mean ‘F_T_EE’? publisher_frankastate.msg_.F_T_NE[i] = robotstate.F_T_NE[i]; ^~ F_T_EE /home/airlab/catkin_ws/src/franka_ros_interface/franka_interface/src/robot_state_controller.cpp:370:64: error: ‘struct franka::RobotState’ has no member named ‘NE_T_EE’; did you mean ‘O_T_EE’? publisher_frankastate.msg_.NE_T_EE[i] = robotstate.NE_T_EE[i]; ^~~ O_T_EE /home/airlab/catkin_ws/src/franka_ros_interface/franka_interface/src/robot_state_controller.cpp: In member function ‘void franka_interface::CustomFrankaStateController::publishTransforms(const ros::Time&)’: /home/airlab/catkin_ws/src/franka_ros_interface/franka_interface/src/robot_state_controller.cpp:474:74: error: ‘struct franka::RobotState’ has no member named ‘F_T_NE’; did you mean ‘F_T_EE’? tf::StampedTransform stamped_transform(convertArrayToTf(robotstate.F_T_NE), time, ^~ F_T_EE /home/airlab/catkin_ws/src/franka_ros_interface/franka_interface/src/robot_state_controller.cpp:480:76: error: ‘struct franka::RobotState’ has no member named ‘NE_T_EE’; did you mean ‘O_T_EE’? stamped_transform = tf::StampedTransform(convertArrayToTf(robotstate.NE_T_EE), time, ^~~ O_T_EE

Hi I also raised this issue in your panda_simulator repository. I am sorry for that. I think it is better to close that one and comment here.

I am certain that i am using franka_ros v0.7.1:

xxxx@Airlab:~/catkin_ws/src/franka_ros$ git branch -a
* (HEAD detached at 0.7.1)
  kinetic-devel
  remotes/origin/HEAD -> origin/kinetic-devel
  remotes/origin/develop
  remotes/origin/disconnect_api_beta
  remotes/origin/kinetic-devel
  remotes/origin/lunar-devel
  remotes/origin/melodic-devel
  remotes/origin/multi_panda_beta
  remotes/origin/noetic-devel

However, it still cannot catkin build... same error..

Try a clean build of your workspace by removing all broken builds. You can do this by removing the 'build' and 'devel' directories in the catkin workspace.

[Sission]

Thank you so much for your help. I understand that. However, I do not think it is the issue. My workspace only have franka_ros, libfranka and your repositories. I tried to remove all your packages and did catkin_make -DCMAKE_BUILD_TYPE=Release -DFranka_DIR:PATH=/path/to/libfranka/build It works fine. I can use $ roslaunch franka_control franka_control.launch robot_ip:=xxxx $ roslaunch panda_moveit_config panda_moveit.launch to control the real robot. However, it can not catkin build after I add your packages..

I really appreciate your help. If you still believe it is my workspace problem, I can close this issue and thank you very much for your help.

I just tried a clean build and did not face any issue. I am not sure why it fails for you if you are indeed using the specified versions.

[justagist]

I just noticed that you said you're using v0.7.0 of libfranka! The README explains that you have to use the release version of the library, which is 0.8.0. The missing robot state variables are only introduced from this version.

[Sission]

damn it! That is my bad! Sorry! The FCI says franka_ros can work with libfranka >=0.6.0... I guess I have to use the older version then. My robot doesn't support >=4.0.0 version. Thank you very much!

[justagist]

You are right, the FCI documentation does say that.. I should probably make it explicit that v0.7.1 of this repo requires libfranka 0.8.0. P.S. If you can, I would recommend you update the firmware of the robot to >=4.0.0.

[Sission]

Thanks! I contacted them but they told me that my robot is too old that it can not be upgrade to >= 4.0.0.. SAD

[Sission]

Hi! Just want to let you know that everything works after changing to v0.6.0. I have a question: Does your package provide some nodes can visualize the robot in Gazebo real-time while controlling a real robot?

[justagist]

Not in Gazebo, but the robot can be visualised in RViz realtime.
