ROS2 Service Client
This node is a generic service client that provides interface for a ROS service. The request/response fields of the service are parsed and are made accessible via the node based on the service specified from messagePackage, messageSubfolder, messageName. The client sends a request (commanded from the node inputs) and receives a response (accessible from the node outputs) from the server.
Installation
To use this node enable omni.isaac.ros2_bridge in the Extension Manager.
