# QIR SDK sample applications

The QIR SDK provides various sample applications. You can use ROS 2 to obtain device CPU load, accelerate AI model inference on Qualcomm platform from ROS 2 nodes, and perform robot simulation. The sample applications fall into different categories: AI, robotics, and platform.

By combining different samples, you can implement various functionalities.

## Summary of samples in the QIR SDK

<Note>
  **Note**

  Some samples require specific hardware peripherals. For the required hardware, see the following tables.

  **Warning**

  The images you download from [Download the prebuilt packages](./download-the-prebuilt-packages) are `qcom-robotics-proprietary-image` for the matching development kits.
</Warning>

### Robotics sample applications

QIR SDK provides the following sample applications that demonstrate the robotics functionalities of the platform.

<Warning>
  **Warning**

  Robotics sample applications require the host and development kit to work together.
