Create® 3 Setup

Setup

This section details the setup for your Create® 3 base. Follow Phases 1 and 3 in iRobot's Create® 3 Setup Guide. You should not need to follow Phase 2 since we will provide the latest stable firmware for the base.

Configuration

This section presents the default Interbotix configuration of the LoCoBot's Create® 3 base. This can be found on the Create® 3 webserver accessed through the LoCoBot's computer's web browser (Firefox, etc.) at 192.168.186.2/ros-config if connected over the base's USB-Ethernet interface.

Warning

Make sure that your Create® 3 base is configured to this default, otherwise it may not work properly or you may experience unexpected behavior.

Note

If you modify any of these configurations, make sure to save the changes and restart the application for them to take effect.

Main configuration

ROS 1ROS 2

Field	Interbotix Default Value	Notes
ROS 2 Domain ID	0	This value is typically left as the default if you do not have multiple ROS domains on the same network. See ROS 2 Domain ID Documentation.
ROS 2 Namespace	/mobile_base	The value dictates the namespace under which all Create® 3 nodes, topics, services, actions, and parameters will be, i.e. the /tf topic published by the base will be /mobile_base/tf.
RMW_IMPLEMENTATION	rmw_fastrtps_cpp	This value tells which RMW implementation to use. See ROS 2 RMW Implementation Documentation.
Enable Fast DDS discovery server?		Left blank as the ROS 1 implementation does not use the Fast DDS discovery server.
Address and port of Fast DDS discovery server		Left blank as the ROS 1 implementation does not use the Fast DDS discovery server.

Attention

The application still needs to restart to take effect. To do this, you can either reboot the robot using the physical power button or its RobotPower service, or use a web browser to reset the application manually.
