Core

Create ROS Core

Description

The ROS Core encompasses many key components and nodes that are essential for the ROS network. You must have exactly one ROS core running in the ROS network for nodes to communicate. Using this class allows the creation of a ROS core in MATLAB^®. Once the core is created, you can connect to it by calling rosinit or ros.Node.

Creation

Syntax

core = ros.Core

core = ros.Core(port)

Description

core = ros.Core returns a Core object and starts a ROS core in MATLAB. This ROS core has a default port of 11311. MATLAB allows the creation of only one core on any given port and displays an error if another core is detected on the same port.

core = ros.Core(port) starts a ROS core at the specified port, port.

Properties

Port — Network port at which the ROS master is listening

Read-only: 11311 (default) | scalar

This property is read-only.

Network port at which the ROS master is listening, returned as a scalar.

MasterURI — The URI on which the ROS master can be reached

Read-only: 'http://<HOSTNAME>:11311' (default) | character vector

This property is read-only.

The URI on which the ROS master can be reached, returned as a character vector. The MasterURI is constructed based on the host name of your computer. If your host name is not valid, the IP address of your first network interface is used.

Examples

Create ROS Core On Specific Port

Create a ROS core on localhost and port 12000.

core = ros.Core(12000)
