Operating System Reinstallation

System Reinstallation

In some cases, you will need to restore your Lynx system to its default settings:

  • in case of accidental damage to the system
  • to update the OS
  • to clear all user changes and restore factory settings

User Computer System Reinstallation

This process varies depending on your computer model. Please select your User Computer model and follow the instruction.

Intel NUC is compatible with the Husarion OS image. To install Husarion OS, please follow this guide.

Choosing a distribution

In the case of a User Computer, you should install the same distribution of ROS that is on the Build in Computer.

Additional information

The installation process cannot be performed in headless mode. Connection to a monitor and keyboard is required.

Built-in Computer System Reinstallation

This computer is used to manage all the basic functions of a mobile platform. The reinstallation procedure for the Built-in Computer is as follows:

  1. The robot Built-in Computer is located in the Service Space. To access it, follow the instructions in the section - (Work in progress) Service Space.

  2. Extract the SD card from the Built-in Computer by carefully pulling it out.

    REPLACING THE SD CARD

    If you want to use your own SD card, make sure it has at least 32 GB of capacity and 10 Speed Class.

  3. Download our custom OS image for the Built-in Computer.

  4. Flash the image onto an SD card (For this process, we recommend using Balena Etcher, steps may vary depending on the software used for flashing):

    • Download Balena Etcher and install it.
    • Plug the SD card into an SD card reader.
    • Open Etcher and select from your hard drive the .img.xz file.
    • Select the SD card you wish to write your image to.
    • Click Flash! to begin writing data to the SD card.
    • Wait for the flashing and validation steps to finish.
  5. Insert the SD card back into the Built-in Computer. Turn the robot on.

    note

    First boot of the robot after system reinstallation may take a bit longer than usual.

  6. Access the Built-in Computer (remember, you must be connected to the Lynx hotspot):

    user@mylaptop:~$
    ssh husarion@10.15.20.2
  7. In order to complete system reinstallation your robot will need Internet connection. If your robot is not yet connected to the Internet please follow: Connecting Lynx to Your WiFi Network
