Software Bringup

This sensor is included in the Clearpath Robotics robot package that is installed on all of our robots. This allows you to add or remove the sensor from your robot's software description by modifying the robot configuration yaml.

Package and Setup

The Intel Realsense cameras use the realsense_ros ROS 2 driver. The driver is open source, maintained by Intel, and hosted on GitHub. The realsense_ros nodes depends on the the librealsense2 SDK. Both packages will be installed alongside the clearpath_sensors package.

For specifics on the way Clearpath's configuration system launches the camera, see the Intel Realsense launch file and the default parameter file in clearpath_sensors.

Device Type and Serial Number

The device_type and serial_no parameters must be set accurately to successfully launch the node. Both of these values can be found using the SDK utility.

Use the following command to see a list of connected Intel Realsense devices:

rs-fw-update

When ran without any arguments, the rs-fw-update will return information about the connected devices, as is shown below:

Nothing to do, run again with -h for help

Connected devices:
1) Name: Intel RealSense D435, serial number: 045322073417, update serial number: 041323020523, firmware version: 5.12.13.50, USB type: 3.2

The device_type is the alpha-numerical sequence in the name. In the example above, set device_type to d435.

The serial_no is the string following the serial number entry. In the example above, set serial_no to "045322073417". Make sure to use quotes to ensure that the serial number is interpreted as a string.
