Here is an example workflow how to create a workspace to test the availability: :: activate the ROS environment c:\opt\ros\melodic\x64\setup.bat :: create a empty workspace mkdir c:\catkin_ws\src cd c:\catkin_ws :: generate the released package sources list and its ROS dependencies :: you can customize the command line to checkout the sources. from ._BatteryState import * Also, try entering rospack find [package_name] into the terminal to find the path to the package. (If I remember correctly, if you don't want to type in source devel/setup.bash every time you open up a new terminal you can edit the bash.rc file.)

Thank you Is it possible to hide or delete the new Toolbar in 13.1? The installation of the rosserial_arduino package now also installs arduino-core, so there's nothing additional needed to make this work. For example: It automatically handles setup, publishing, and subscribing for a connected rosserial-enabled device. In any case, our "real world" rosserial_server instances have an overall footprint in the 100s of MB, so I don't think the cost of keeping the interpreter instance around is worth worrying too much about. i'm working with a arduino mega 2560 on ubuntu 12.04 i wish you can help me with this problem.
