Launch Notes for B3RB:
# serial terminal to NavQPlus
screen /dev/ttyUSB0 115200
# Setup wifi hotspot on phone.
# same network as host PC
# show local wifi networks, find the one you want
sudo nmcli device wifi
# for a text interface
sudo nmtui
# Connect NavQPlus Wifi to network
sudo nmcli device wifi connect <network name> password <password>
When Foxglove starts, "Open Connection" and type connect to
ws://b3rb-xx.local:4242
(replace b3rb-xx with whatever your buggy's hostname is)
# SSH login to NavQPlus
ssh user@mrb3rb
#or
ssh user@mrb3rb.local
# FIRST launch Ros2 electrode on host pc
ros2 launch electrode
electrode.launch.py
rviz2:=false
# Then launch Ros2 on B3RB
ros2 launch b3rb_bringup robot.launch.py
If there are multiple vehicles being used at the same time on the same network, then you will also need to set a unique ROS_DOMAIN_ID for on both the host LInux machine and the NavQPlus
edit your file ~/.bashrc
using VIM, NANO or GEDIT
change the line (find with CTRL+W)
export ROS_DOMAIN_ID=xxx
where xxx is a unique number from the other robots
Sometimes you just want to start over. It's ok, we all have days like that. I Fyou need afresh cognipilot start, and want to be extra sure there are no leftover dependencies or files you dont' want etc then follow these steps. Keep in mind this is going to erase local changes you may have made to cognipilot files. Note them in advance if you want to re-do the changes afterwards. (for example you may have disabled the battery voltage check in <todo> xxx.conf)
Then start again with the cognipilot install instructions for the Linux host development PC.

The instructions above will take care of Gazebo install also. If you happen to know you are stuck on an old version of Gazebo you may want to just try this first. The example below is where gazebo "garden" (gzgarden) is installed, but you want gazebo "harmonic"
Setting up B3RB with CogniPilot environment software
The definitive guide is the CogniPilot website, these sub-pages are only for additional details and guidance.
At ths point you are ready to use the MR-B3RB. If you have reviewed the documentation you should now:
You can log into the NavQPlus console and even into the MR-CANHUBK344 running CogniPilot/Zephyr
You can run ROS SIL or "real hardware" examples using RVIZ or Foxglove as a control station.
The vehicle is capable of being safely armed through several steps and autonomously navigating to a position and pose as specified/pointed to on the control station software.
OPTIONAL: When booted, if you have a console connected, MR-CANHUBK344 will display the following CogniPilot logo and welcome screen on the console.
Within a few seconds, the red light on the T1 Ethernet port on both the boards should light up.

From the command line run
Login to the NavQPlus using ssh or serial console.
Ensure the NavQPlus and Host PC are on the same network
AFTER starting ROS on the Host PC, THEN on the NavQPlus run
