# Run platform sample applications

Platform sample applications enable the basic functionalities using the QIR SDK on the Qualcomm Dragonwing<sup>TM</sup> kits.

* [Enable Orbbec Gemini 335L with orbbec\_camera](./enable-orbbec-gemini-335-l-with-orbbec-camera)

  The `orbbec_camera` sample application enables the Orbbec Gemini camera 335L to work in RGB or depth mode. This application generates the RGB and depth information by topics.
* [Enable basic RPLIDAR handling with rplidar-ros2](./enable-basic-rplidar-handling-with-rplidar-ros2)

  The `rplidar-ros2` sample application provides basic device handling for the 2D laser scanner RPLIDAR A1/A2/A3/S1/S2/S3.
* [Publish system status with qrb\_ros\_system\_monitor](./publish-system-status-with-qrb-ros-system-monitor)

  The `qrb_ros_system_monitor` sample application has various ROS nodes that publish system status information, such as CPU loading, memory usage, and disk space.
* [Run basic OCR with ocr\_service](./run-basic-ocr-with-ocr-service)

  The `ocr_service` sample application enables a service that provides the Optical Character Recognition (OCR) function.
* [Execute AI model inference with qrb\_ros\_nn\_inference](./execute-ai-model-inference-with-qrb-ros-nn-inference)

  [qrb\_ros\_nn\_inference](https://github.com/qualcomm-qrb-ros/qrb_ros_nn_inference) is a ROS 2 package for performing neural network model inference, providing AI-based perception for robotics applications.
