Getting error while launching perception pipeline

[nirutheshark]

We are trying to launch a pick and place usecase for wx200 robot arm. using following command on a RPi4
roslaunch interbotix_xsarm_perception xsarm_perception.launch robot_model:=wx200 use_pointcloud_tuner_gui:=true use_armtag_tuner_gui:=true

The isolated build was successful for us but we get these error in our run
ERROR: cannot launch node of type [interbotix_perception_modules/perception_pipeline]: Cannot locate node of type [perception_pipeline] in package [interbotix_perception_modules]. Make sure file exists in package path and permission is set to executable (chmod +x)

ERROR: cannot launch node of type [apriltag_ros/apriltag_ros_single_image_server_node]: Cannot locate node of type [apriltag_ros_single_image_server_node] in package [apriltag_ros]. Make sure file exists in package path and permission is set to executable (chmod +x)

is there anything we are missing?

Hi @nirutheshark.

The default rpi4 install script doesn't install the perception toolbox and doesn't support perception operations.

We strongly recommend using a computer with better performance like the Intel NUC, but I believe it is possible to run the librealsense and realsense_ros packages alongside the Interbotix control software on an RPi4. Note that you may suffer some serious performance issues when running the perception pipeline. The librealsense installation is somewhat complicated on an arm64 device running Ubuntu MATE and you're welcome to try to figure it out on your own, but the process is unfortunately not supported by Trossen Robotics.

Take a look at the ROS1 perception installation section of the amd64 install script for details.
