rossubscriber

Subscribe to messages on a topic

expand all in page

Description

Use rossubscriber to create a ROS subscriber for receiving messages on the ROS network. To send messages, use rospublisher. The most reliable method to receive messages continuously as they are published on the ROS network is to create a callback for the rossubscriber object. For more information, see Create A Subscriber That Uses A Callback Function. Alternatively, to wait for a new ROS message, use the receive function with your created subscriber.

The Subscriber object created by the rossubscriber function represents a subscriber on the ROS network. The Subscriber object subscribes to an available topic or to a topic that it creates. This topic has an associated message type. Publishers can send messages over the network that the Subscriber object receives.

Note

In a future release, ROS Toolbox will use message structures instead of objects for ROS messages.

To use message structures now, set the "DataFormat" name-value argument to "struct". For more information, see ROS Message Structures.

You can create a Subscriber object by using the rossubscriber function, or by calling ros.Subscriber:

  • rossubscriber works only with the global node using rosinit. It does not require a node object handle as an argument.

  • ros.Subscriber works with additional nodes that are created using ros.Node. It requires a node object handle as the first argument.

Creation

Syntax

sub = rossubscriber(topicname)
sub = rossubscriber(topicname,msgtype)
sub = rossubscriber(topicname,callback)
sub = rossubscriber(topicname, msgtype,callback)
sub = rossubscriber(___,Name,Value)
sub = rossubscriber(___,"DataFormat","struct")
sub = ros.Subscriber(node,topicname)
sub = ros.Subscriber(node,topicname,msgtype)
sub = ros.Subscriber(node,topicname,callback)
sub = ros.Subscriber(node,topicname,type,callback)
sub = ros.Subscriber(___,"BufferSize",value)
sub = ros.Subscriber(___,"DataFormat","struct")

Description

sub = rossubscriber(topicname) subscribes to a topic with the given TopicName.The topic must already exist on the ROS master topic list with an established message type. When ROS nodes publish messages on that topic, MATLAB® receives those messages through this subscriber.

example

sub = rossubscriber(topicname,msgtype) subscribes to a topic that has the specified name, TopicName, and type, MessageType. If the topic list on the ROS master does not include a topic with that specified name and type, it is added to the topic list. Use this syntax to avoid errors when subscribing to a topic before a publisher has added the topic to the topic list on the ROS master.

sub = rossubscriber(topicname,callback) specifies a callback function, callback, that runs when the subscriber object handle receives a topic message. Use this syntax to avoid the blocking receive function. The callback function can be a single function handle or a cell array. The first element of the cell array must be a function handle or a string containing the name of a function. The remaining elements of the cell array can be arbitrary user data that is passed to the callback function.

example

sub = rossubscriber(topicname, msgtype,callback) specifies a callback function and subscribes to a topic that has the specified name, TopicName, and type, MessageType.

sub = rossubscriber(___,Name,Value) provides additional options specified by one or more Name,Value pair arguments using any of the arguments from previous syntaxes. Name is the property name and Value is the corresponding value.

sub = rossubscriber(___,"DataFormat","struct") uses message structures instead of objects. For more information, see ROS Message Structures

sub = ros.Subscriber(node,topicname) subscribes to a topic with name, TopicName. The node is the ros.Node object handle that this publisher attaches to.

sub = ros.Subscriber(node,topicname,msgtype) specifies the message type, MessageType, of the topic. If a topic with the same name exists with a different message type, MATLAB creates a new topic with the given message type.

example

sub = ros.Subscriber(node,topicname,callback) specifies a callback function, and optional data, to run when the subscriber object receives a topic message. See NewMessageFcn for more information about the callback function.

sub = ros.Subscriber(node,topicname,type,callback) specifies the topic name, message type, and callback function for the subscriber.

sub = ros.Subscriber(___,"BufferSize",value) specifies the queue size in BufferSize for incoming messages. You can use any combination of previous inputs with this syntax.

sub = ros.Subscriber(___,"DataFormat","struct") uses message structures instead of objects. For more information, see ROS Message Structures

Properties

expand all

This property is read-only.

Name of the subscribed topic, specified as a string scalar or character vector. If the topic does not exist, the object creates the topic using its associated message type.

Example: "/chatter"

Data Types: char | string

This property is read-only.

Message type of subscribed messages, specified as a string scalar or character vector. This message type remains associated with the topic.

Example: "std_msgs/String"

Data Types: char | string

Latest message sent to the topic, specified as a Message object. The Message object is specific to the given MessageType. If the subscriber has not received a message, then the Message object is empty.

Buffer size of the incoming message queue, specified as the comma-separated pair consisting of "BufferSize" and a scalar. If messages arrive faster than your callback can process them, they are deleted once the incoming queue is full.

MATLAB has a default recursion limit of 500. Hence, if you are specifying a buffer size value N greater than 500, you must change the MATLAB recursion limit to N using this code:

set(0,'RecursionLimit',N)
Ensure that you do not specify excessively high recursion limit which results in exceeding your available stack space.

Callback property, specified as a function handle or cell array. In the first element of the cell array, specify either a function handle or a string representing a function name. In subsequent elements, specify user data.

The subscriber callback function requires at least two input arguments. The first argument, src, is the associated subscriber object. The second argument, msg, is the received message object. The function header for the callback is: 

function subCallback(src,msg)

Specify the NewMessageFcn property as:

sub.NewMessageFcn = @subCallback;

When setting the callback, you pass additional parameters to the callback function by including both the callback function and the parameters as elements of a cell array. The function header for the callback is: 

function subCallback(src,msg,userData)

Specify the NewMessageFcn property as:

sub.NewMessageFcn = {@subCallback,userData};

Message format, specified as "object" or "struct". You must set this property on creation using the name-value input. For more information, see ROS Message Structures.

Initializing ROS master on http://172.20.18.150:52306.
Initializing global node /matlab_global_node_48094 with NodeURI http://dcc576260glnxa64:43247/ and MasterURI http://localhost:52306.

Setup a publisher to publish a message to the '/chatter' topic. This topic is used to trigger the subscriber callback. Specify the Data property of the message. Wait 1 second to allow the publisher to register with the network.

pub = rospublisher('/chatter','std_msgs/String','DataFormat','struct');
msg = rosmessage(pub);
msg.Data = 'hello world';
pause(1)

Set up a subscriber with a specified callback function. The exampleHelperROSChatterCallback function displays the Data inside the received message.

sub = rossubscriber('/chatter',@exampleHelperROSChatterCallback,'DataFormat','struct');
pause(1)

Send the message via the publisher. The subscriber should execute the callback to display the new message. Wait for the message to be received.

send(pub,msg);
pause(1)
ans = 
'hello world'
