You can follow this tutorial to manually launch the Niryo One ROS stack on the Raspberry Pi board. 🙂
If the auto launch on start up is no longer working, it means that maybe you changed or broke some configuration.
Try to execute the command “sudo systemctl enable niryo_one_ros.service” and reboot the robot. If it still doesn’t work, check about your systemd configuration and the list of services that are launched on boot.
Also, if at some point you’re completely stuck, you can always download and reflash a new image on the SD card.
