 ==== Hokuyo LAN Config ====
-When connecting the Hokuyo laser sensor via LAN, the connection must be configured manually. This way, the laptop can directly communicate with the LIDAR. Connect the Battery to the Tortugabot to give power to the Hokuyo LIDAR, then connect it via LAN to this laptop. Open Wired Settings and configure the profile. Set IPv4 to Manual and give it an IP and Submask.
