CONNECT BY SSH.

Join the car's Wi-Fi from your laptop, the network named neoracer-[Car ID] with the password neobotics. Car ID is the number on your unit, so Car 1 broadcasts neoracer-1 and answers at 192.168.1.101. Then SSHi in as racecar:

bashCopy
# After joining the car's Wi-Fi (neoracer-[Car ID]).
ssh racecar@neoracer            # by hostname
ssh racecar@192.168.1.101       # or the static IP (Car 1)
# password: neobotics

• The address is static and deterministic, so there is no IP to hunt for and no DNS to configure. Car N is always at 192.168.1.{100 + N}.
• Because the car runs its own network, this works the same on any Wi-Fi-hostile venue. Nothing depends on the room's router.
• The username is racecar, the hostname is neoracer, and the password can be changed per unit.

HEADLESS IN A BROWSER.

JupyterLab runs on the car as an auto-start service, so once you're on its Wi-Fi you can open a notebook from any browser with no terminal at all. It lives on port 8888 at the same static address.

bashCopy
# In a browser on the car's Wi-Fi, for Car 1:
http://192.168.1.101:8888

ROS 2 DISCOVERY.

Once your laptop is on the car's Wi-Fi, you share the 192.168.1.x subneti, and ROS 2 uses DDS discoveryi to find the car nodes automatically. You can list the car's topics and run nodes on the laptop that talk to /scan, /drive, and the rest, with no master process in between (the driver has to be running on the car first, with teleop).

bashCopy
# From your laptop, on the car's Wi-Fi.
ros2 topic list                  # /scan /drive /imu /odom /camera /joy
ros2 topic echo /scan --once     # a single scan, straight off the car
