A plugin to enable DialogOS to send messages into arbitrary ROS topics

This plugin enables to send messages to ROS topics e.g. to control robot actions.

Plugin settings control ROS_MASTER_URI and ROS_IP, nodes specify the topics they publish/subscribe to.

Publishing messages to ROS topics:

Use a ROSOutputNode to send (=publish) a message to any ROS topic.

Messages to be sent can be DialogOS script expressions, i.e., if you don't want to send just a fixed string, you can enter an expression. To force sending fixed strings, try "quotes".

Messages to be sent are always typed as std_msgs/String.

Subscribing to messages on ROS topics:

Use a ROSInputNode to receive messages on any ROS topic (subscription).

Multiple messages may accumulate in the subscribed topic and hence the node will return a list of messages into a List variable. You specify what (list) variable to store the results into. If you want your node to wait for at least one message (since the last call) to appear in the topic, you can set the corresponding check mark in the node properties.

Messages to be received must be typed std_msgs/String.
