# Open-source samples Source: [https://docs.qualcomm.com/doc/80-70015-265/topic/open-source-samples_5_2.html](https://docs.qualcomm.com/doc/80-70015-265/topic/open-source-samples_5_2.html) Open-source sample applications are available to all users of QIRP SDK. - **[Nav2-bringup](https://docs.qualcomm.com/doc/80-70015-265/topic/nav2-bringup_5_2_1.html)** The nav2-bringup ROS sample enables the ROS2 navigation framework and system. It provides perception, planning, control, localization, visualization, and much more to build highly reliable autonomous systems. - **[Librealsense2](https://docs.qualcomm.com/doc/80-70015-265/topic/librealsense2_5_2_2.html)** Librealsense2 and realsense2-camera are used to make RealSenseā„¢ camera D455 work properly in RGB or depth mode. This application can generate the mono and depth information by topics. - **[Rplidar-ros2](https://docs.qualcomm.com/doc/80-70015-265/topic/rplidar-ros2_5_2_3.html)** The rplidar-ros2 sample provides basic device handling for the 2D laser scanner RPLIDAR A1/A2/A3/S1/S2/S3. - **[QRB-ROS-IMU](https://docs.qualcomm.com/doc/80-70015-265/topic/qrb-ros-imu_5_2_4.html)** The QRB-ROS-IMU sample creates the `/imu` topic to publish the inertial measurement unit (IMU) data. - **[QRB-ROS-CAMERA](https://docs.qualcomm.com/doc/80-70015-265/topic/qrb-ros-camera_5_2_5.html)** QRB-ROS-CAMERA implements a camera ROS2 node to enable zero-copy performance when data is coming out of the camera-server. This sample greatly reduces the latency between ROS nodes. - **[QRB-ROS-SYSTEM-MONITOR](https://docs.qualcomm.com/doc/80-70015-265/topic/qrb-ros-system-monitor_5_2_6.html)** QRB-ROS-SYSTEM-MONITOR contains various ROS nodes to publish system status information, such as CPU loading, memory utilization, and disk spaces. - **[OCR-service](https://docs.qualcomm.com/doc/80-70015-265/topic/ocr-service_5_2_7.html)** The `ocr-service` sample enables a service that provides the Optical Character Recognition (OCR) function. **Parent Topic:** [QIRP SDK sample applications](https://docs.qualcomm.com/doc/80-70015-265/topic/qirp-sdk-sample-applications_5.html) Last Published: Oct 15, 2024 [Previous Topic Install Rviz2](https://docs.qualcomm.com/bundle/publicresource/80-70015-265/topics/install-rviz2_5_1_3.md) [Next Topic Nav2-bringup](https://docs.qualcomm.com/bundle/publicresource/80-70015-265/topics/nav2-bringup_5_2_1.md)
