Description

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:

The Rd-03D radar 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.
