Package Summary

Service pair libraries for pub/sub non-blocking services.


This package is a collection of extensions that go above and beyond what the family of core ros modules (rospy, rosmaster, rostopic, rosnode, rosservice...) do for enabling the ros middleware with python.


Full details and usage examples are in the sphinx documentation (indigo), the following is just a brief reference of what is available.

  • find_xxx : helpers for finding nodes, topics and services.

  • SubscriberProxy : similar to a service proxy (client), but works with a latched topic.

  • ServicePairs : use pub-sub pairs for blocking/non-blocking request-response behaviour (c.f. actionlib).


Only available in indigo and beyond.
