JetBot ROS AI Kit Basic Tutorial

Step 1: Program Jetson Nano Image

  • Tip: If you have bought a whole package, you will get an SD card with a programmed image, and you can skip this step.
  • The configured image is provided here. If you want to configure the image by yourself, you can refer to the advanced tutorial. It is recommended to use our configured image for the first time to avoid problems when configuring the image yourself.
  • Prepare an SD card (minimum 64G) and insert it into the computer with a card reader.
  • Please use SDFormatter to format the SD card. [Note that other storage devices should be disconnected when formatting so as to prevent misoperation.]

  • Unplug the mouse, keyboard and other peripherals, and we can perform SSH remote login.

Step 2: Connect Jetson Nano to WiFi (without Display)

  • Connect the network cable to the Jetson Nano, and then the Jetbot will display the IP address of the network cable [Note: Your PC and Jetson Nano should be connected to the same route to ensure the same network segment, otherwise SSH remote login will fail].
  • Click to download MobaXterm software for SSH remote login.
  • Open MobaXterm, click "Session -> SSH", fill in the IP address displayed by the car in the host, and press Enter to open the terminal; the login name and password are jetbot.

Step 4: SSH Remote Login

  • In the previous steps, we connected the jetson nano and the PC host to the same WiFi, and after restarting the jetson nano will generally remain connected to the original WiFi, and the IP will remain unchanged.
  • In the following operations, we all use SSH remote login to start the robot node.
  • When the jetson nano is powered on, the OLED screen of the car will display the IP address of the last connected WiFi. At this time, the IP address of the WiFi will be displayed first. If the WiFi is not connected, the IP address of the wired network port will be displayed.

Step 5: Get Virtual IP and Hostname

  • Open the robot terminal and enter the following command, check the IP and hostname of the Jetson Nano and remember that it will be used for subsequent multi-machine communication.
ifconfig #Get the IP address of the virtual machine
hostname #Get the hostname of the virtual machine
