Access Information

This section provides details about how to connect to the Robot PC from the User PC, including network addresses, credentials, and Web UI access.

Network Information:

• Robot PC IP Address (User PC to Robot PC): 192.168.30.1

• Robot PC IP Address (Hotspot Connection: 192.168.12.1

  • Hotspot SSID: RBY1
  • Hotspot Password: The password can be viewed after connecting via QR code.

    🔑 Connecting via QR Code

    1. Press the HOTSPOT button on the top of the robot's backpack to activate the hotspot.
    2. A QR code will be displayed; scan it to automatically connect to the network.

    • The hotspot will remain active only while the HOTSPOT button is pressed.
    • Ensure the button is not pressed again during robot operation, as this will deactivate the hotspot and disrupt communication with the robot.

Web UI Access

• User PC(UPC) to Robot PC(RPC): 192.168.30.1:5173
• Hotspot Connection: 192.168.12.1:5173

Access Credentials

• User PC Username: nvidia
• User PC Password: nvidia

⚠️ Note
The default credentials are standard for Nvidia Jetson devices.

Command Information

• Command Port: 50051 (Use this port to send commands to the Robot PC.)

Sending Commands to the Robot

From the User PC (UPC)

1. Direct Command via Code:

   • Send commands to the Robot PC at 192.168.30.1:50051 from the UPC by writing code that interfaces with the robot.

2. SSH Connection:

   • You can also SSH into the UPC and send commands to the Robot PC at 192.168.30.1:50051.

   💡 The UPC only supports wired connections, so if you need a wireless solution, you'll need to implement it manually.

[ (Option 1) Using included PC as UPC ]

From Another PC(Your own PC)

There are two methods to send commands to the Robot PC from another PC:

1. Using Hotspot:

   • Connect the other PC to the same Wi-Fi as the Robot PC via the HOTSPOT.
   • Send commands to 192.168.12.1:50051.

2. Using a Separate Wi-Fi Network:

   • Connect the Robot PC and your PC to a different Wi-Fi network.
   • Assign the Robot PC to that Wi-Fi network.
   • Send commands to the Robot PC's IP address on the same network, followed by :50051 for the command port.
   • More detailed instructions on this method will be provided later.

[ (Option 2) Using your own PC as UPC ]

LiDAR Information

You can access the LiDAR sensors via the following IP addresses:

• Left LiDAR IP Address: 192.168.30.10
• Right LiDAR IP Address: 192.168.30.11

Use these addresses to connect to the respective LiDAR sensors for data collection and monitoring.

Additional Information

• The LiDAR sensors used in this system are LakiBeam 1L.
