I install ros melodic on ubuntu18.04 and compile oslsim according instructions. However, when i was running roslaunch oslsim main.launch control:=true, there existed an error as below:

$ roslaunch oslsim main.launch control:=true

... logging to /home/user/.ros/log/7cc08b3c-b647-11ec-8165-30d042e761b4/dell-3175.log

Invalid parameter "robot_ns"

when instantiating macro: dc_motor (/home/user/catkin_ws/src/gazebo_ros_motors/xacro/dc_motor.xacro)

in file: /home/user/catkin_ws/src/oslsim/urdf/oslsim.xacro

RLException: Invalid <param> tag: Cannot load command parameter [robot_description]: command [['/opt/ros/melodic/lib/xacro/xacro', '/home/user/catkin_ws/src/oslsim/urdf/oslsim.xacro']] returned with code [2]. 



Param xml is <param command="$(find xacro)/xacro '$(find oslsim)/urdf/oslsim.xacro'" name="robot_description"/>

The traceback for the exception was written to the log file

It seems that dc_motor.xacro in gazebo does not support robot_ns. How can I figure it out?

I got to run the program by deleting "robot_ns" propety in $(find oslsim)/urdf/oslsim.xacro and resetting gazebo_ros_motors to the commit before "allow specifying axis". But simulation could not carry on. The program ran into segment fault.

Facing the same error, was it resolved?

No. Always the same error

@QiYue-day
Copy link

The first error occurred because in subsequent work, a robot_ns parameter was added to the 'oslsim.xacro' file in the 'oslsim' package, but this parameter was not added to the corresponding motor files, resulting in an error. I attempted to revert oslsim to a previous version (you can check when this parameter was added to avoid it), fortunately, the previous error disappeared. Unfortunately, there are new errors now.
