ROS Service Server/Client

Within a rqt Plugin GenericDomainModel, a ROS Service Server or Client is represented by a GenericDomainModelPort with the following Attributes.

Attributes	Value	Description
Type	service
Attribute 0	[default service name]	Default ROS Service name
Attribute 1
Attribute 2	[msg type]	ROS Service Msg Type - e.g. Trigger
Attribute 7	ros

If the CyPhy Master Interpreter is run, these Attributes will be used to populate the parent rqt Plugin Model’s connected template file Resource.

For each netlist of connected ports, the Interpreter will check that the the port types all match (e.g. a ROS Topic Publisher cannot broadcast to a ROS Service Server) and that the Service Msg types (if specified) all match.

If the port is connected to other ports, a unique ROS Service name will be generated and assigned to ports in that netlist.

Otherwise, Attribute 0’s Value will be used.

The ROS Service Client or ROS Service Server Port’s name is used as a key to populate the rqt Plugin Model’s connected template file Resource with the ROS Service name.
