MoveIt setup assistant not loading meshes; unable to find package name within the ROS workspace

Hello everyone!

I have exported a hand SolidWorks assembly file into a URDF using a the sw_urdf SolidWorks addon. I have defined the joint tree and wanted to move onto setting it up fully using MoveIt setup assistant. When I tried loading the file into it I have received the following error:

ROS was unable to find the package name hand within the ROS workspace. This may cause issues later.

This is strange as I have followed this guide when importing the generated URDF into my ROS workspace and it involved generating a package.

After I click OK to carry on and load the URDF into the setup assistant I get the following errors for every link I have (the example provided is a sample):

[rospack] Error: package 'hand.urdf' not found It seems that because MoveIt did not spot the package directory it couldn't find the meshes directory. I am unsure how to resolve this issue as I did setup a ROS package using catkin_create_pkg command.

I will be very grateful if someone could guide me regarding this problem.

Before opening the moveit assistance, you must source the workspace where your robot's description package is located.

Something like you have ~/catkin_ws/src/my_robot_description


to build your pkg, you can use catkin_make or catkin build. after building the package, you must source devel/setup.bash before launching the moveit setup assistance from the same sourced terminal.

In the end I just had to add the custom hand package to the MoveIt workspace. It's not as neat as I was hoping for since I wanted to apply MoveIt to multiple workspaces. Unfortunately I had to rebuild the whole of the MoveIt workspace. Maybe I'm missing something, but I just wasn't able to source two workspaces.
