ROS rx
Helpers used to convert to/from ROS topics and observables.
Helpers
Subscribe to a topic as an observable
The method observabletopic() supports the same signature as rospy.Subscriber.
Example:
from rosrx import observabletopic
from std_msgs.msg import String
source = observabletopic('/chatter', String)
source.subscribe(lambda msg: rospy.loginfo(msg.data))
Publish observable values to a topic
from rosrx import TopicObserver
from std_msgs.msg import String
from rx import interval
from rx.operators import map
source = interval(1.0)
source.pipe(map(lambda value: 'hello world {}'.format(value))).subscribe(
observer=TopicObserver('/chatter', String, queue_size=1))
