Work around (temporary) solution: Steps to manually launch Niryo One from the command line.
Indication: (after ssh to Niryo One)
niryo@niryo-pc:~$ rosnode list
ERROR: Unable to communicate with master!
Problem: ROS Stack is not running
Solution: Configure environment to launch ROS Stack on start up (this is not longer working for me)
Work around: Lauch ROS Stack manually:
niryo@niryo-pc:~$ roslaunch niryo_one_bringup rpi_setup.launch
