== Overview ==

`std_srvs` contains two service types called `Empty` and `Trigger`, which are common service patterns for sending a signal to a ROS node. For the `Empty` service, no actual data is exchanged between the service and the client. The `Trigger` service adds the possibility to check if triggering was successful or not. 

For common message definitions, please see the [[std_msgs]] package.
