1. Project Overview
This project is a smart human tracking rotating platform designed based on the STM32F103C8T6 and Rd-03D. It can adjust the rotating platform to the corresponding angle according to the movement position of a person within a space.
2. Project Features
- Automatic Rotation Function:
It can detect the trajectory of human movement in real-time to obtain the corresponding spatial coordinates. By calculating the angle from these coordinates and driving the stepper motor, the platform rotates to the correct position without manual operation.
- Unmanned Calibration Function:
When there is no one in the space, the stepper motor automatically returns to the initial central position.
3. Project Specifications
- Utilizes the AI-Thinker 24G millimeter-wave radar module — Rd-03D, which includes an intelligent positioning and tracking algorithm capable of detecting multiple targets in a designated area and reporting results in real-time. It accurately perceives human and area motion states, with integrated smart algorithms for motion trajectory recognition and tracking, enabling speed and distance measurement of targets within the area.
- Features the STM32F103C8T6 chip, a classic and versatile MCU with comprehensive documentation.
- Equipped with a stepper motor, four-phase five-wire, controlled by pulses.
- Powered by a Type-C interface, simple wiring.

5. Structural Design
This project consists of the following parts: a bottom cover, main body (including circuit board), top cover, and rotating platform. 3D casing files are available in the attachment.
6. Precautions
- When multiple people are present, it detects the target with the greatest movement energy.
- Position the radar to face the space to be monitored.
- Keep the detection area as clear as possible.
