step 9, setup_rosbots_code After setting up some other packages (about 30 seconds), it'll ask you for your RPi password. Once you finished that, you can go grab a cup of coffee. When you return, setup should be complete. When complete, type - rosnode list You should see /rosout and /uno_serial_node outputted

Not completing setup_rosbots_code step, see error below.

Arduino uno should be connected to raspberry while you do your installation.
