4.2 Network Configuration

The AntBot computer uses netplan as the network configuration tool.

The interface name is eth0, and the onboard computer’s static IP address is 192.168.6.2.

Unless otherwise requested, AntBot ships with a Wi-Fi router pre-installed. The Wi-Fi SSID is shown as antbot_xxxx. Refer to the separate notice for the password.

SSH Connection to Onboard Computer

1. Connect your laptop to the AntBot Wi-Fi (antbot_xxxx).

   The router is configured with the 192.168.6 internal subnet.

2. Set the laptop’s IP address to the 192.168.6.x range. (Excluding 192.168.6.2 and 192.168.6.5)

   By default, an address in the 192.168.6.x range is assigned automatically via DHCP.

   • 192.168.6.2 — Onboard computer (reserved)
   • 192.168.6.5 — 3D LiDAR (reserved)

3. SSH in using the following command.

   ssh antbot@192.168.6.2

Changing the Onboard Computer Static IP Address
