Without any configuration, the basic robot example can be displayed in the viewer. This robot is simply two geometric components with a single prismatic joint.
To display the basic Niryo and the Burger robot, a ROS environment needs to be configured accordingly in order for the viewer to locate the necessary mesh files, see Tutorial for Configuring ROS Environment.
The following packages are required:
Similarly, Ned, Spot and the T12 robot use robot description ROS packages to store their respective mesh files. These packages will need to be installed locally and the ROS environment configured correctly (
source <workspace>/devel/setup.bash) so that these packages can be accessed.
