Establishing a Robot Connection

To connect a robot, you need to create a robot entry in the system, download the required certificates, and launch the corresponding software in ROS2.

Create a Robot

Navigate to Navigation -> Robots and click Create Robot.

Enter a robot name and press Next.

Realtime Exchange: When enabled, the robot continuously streams data to the server. Disable it for polling-based communication.
Hardware Protection: When enabled, LGDXRobot Cloud verifies the serial numbers of the motherboard and MCU. If they don’t match the records in the database, the connection will be rejected.

Select LGDXRobot2 as the robot type. Enter 0 for the remaining fields, then press Next.

The chassis information does not affect system behaviour. This page is subject to change.

Download all the certificates and press Next, then Done.

The system does not store the robot’s private keys. If lost, you can renew the certificates to generate new ones.

Establishing a Connection

Move all certificates to the robot computer, then run the following commands:

cd lgdx ws
. install/setup.bash
ros2 run lgdxrobot2_daemon lgdxrobot2_daemon_node --ros-args -p cloud_enable:=true -p cloud_address:=192.168.1.10:5162 -p cloud_root_cert:=/home/user/key/rootCA.crt -p cloud_client_key:=/home/user/key/Robot1.key -p cloud_client_cert:=/home/user/key/Robot1.crt

Parameter	Description
cloud_enable	Enables or disables cloud communication. Set to `true` to enable it.
cloud_address	IP address and port of the cloud server to connect to (e.g., `192.168.1.10:5162`).
cloud_root_cert	Path to the root CA certificate. Used to verify the server’s identity.
cloud_client_key	Path to the client’s private key. Used for TLS mutual authentication.
cloud_client_cert	Path to the client’s certificate. Used with the key to authenticate the robot.

If the connection is working, the terminal will show: Connect to the cloud, start data exchange.

And the robot in Robots will be shown as online.
