CONNECT

The CONNECT node establishes a connection to the Mecademic robot arm via HTTP and activates the robot arm. The IP Address to use is the same one that is used to access the Mecademic web interface. Example: 192.168.0.100 Params: ip_address : str The IP address of the robot arm. simulator : bool Whether to activate the simulator or not. Defaults to False. Returns: out : String The IP address of the robot arm, used in other Mecademic nodes to establish which arm they are communicating with.

In this example, the CONNECT node establishes a connection with the MECADEMIC MECA500 robot arm.

The node takes in the IP address of the robot arm as an input. It initializes the handle map and adds a handle for the given IP address.

Upon successful connection, the node returns the IP address, confirming that the robot arm is now connected and ready for further operations.

The CONNECT node is used at the beginning of a workflow to ensure that a connection is established before any other operations are carried out.
