Install Viam dependencies on the TDA4VM

  1. Connect the board to Ethernet.

  2. Connect the board to a monitor with the HDMI cable.

  3. Connect the board to power using the USB-C power cable.

  4. Use the credentials and IP address displayed in the upper right-hand corner of the monitor to SSH into the board.

From the SSH session on the TDA4VM board:

  1. Clone the TDA4VM repo:

    git clone https://github.com/viam-labs/tda4vm-setup.git
    
  2. Navigate to the setup directory:

    cd tda4vm-setup/
    
  3. Make the server setup script executable:

    chmod +x tda4vm-viam-setup.sh
    
  4. Launch the setup script to install viam-server dependencies:

    ./tda4vm-viam-setup.sh
    

    Once this process completes, the board will reboot.

Install viam-server

viam-server is the open-source software that drives your hardware and connects your device to the cloud. Install viam-server on the computer or single-board computer (SBC) that is directly connected to your hardware (for example sensors, cameras, or motors):

  1. Make sure your computer or SBC is powered on and connected to the internet.

  2. Create a Viam account on app.viam.com. You can configure and manage devices and data collection in the web UI.

  3. Create a new machine using the Add machine button in the top right corner of the LOCATIONS tab in the app. A machine represents your device.

  4. On your machine’s page, click View setup instructions.

  5. Select the appropriate architecture for your machine: Linux / Aarch64, Linux / x86_64, or Linux / Armv7l.

    On most Linux operating systems, you can run uname -m to confirm your computer’s architecture.

    If you selected Linux / Aarch 64 or Linux / x86 also select your installation method:

    • viam-agent (recommended): installs viam-agent, which will automatically install (and update) viam-server and provide additional functionality such as provisioning and operating system update configuration.
    • manual: installs only viam-server on your machine.
  6. Follow the instructions on the page to install viam-server and connect it to the cloud with your machine’s unique credentials.

  7. After you install viam-server, a secure connection is automatically established between your machine and Viam. When you update your machine’s configuration, viam-server automatically gets the updates.

    You are ready to configure supported hardware on your machine.

Try an example

Once you’ve installed viam-server and your machine has come online, if your machine has a webcam, you can try an example project:

  1. Click the + icon next to your machine part in the left-hand menu and select Insert Fragment.

    Add the DeskSafariGame fragment by the Robot Land organization and click Insert Fragment. This adds a number of resources to your machine:

    • a camera component which connects to the webcam
    • machine learning resources to run a model and apply it to the camera stream
    • control logic that implements a game
  2. Save your config and review the available resources on the CONFIGURE tab.

  3. Log into this Viam application with your Viam credentials and select your machine. The application provides a UI for playing the game

  4. Select a camera and press the Start Game button. The goal of the game is to find and show specific objects to the camera.

If you’d like to learn how to create this game, see the Desk Safari tutorial.

Should the game not work, return to your machine in the Viam web UI and check the LOGS tab for errors.
