Remote Controlled Metal Detector Robot Project

Introduction

This project involves designing, building, programming, and testing a battery-powered remote-controlled robot that can detect metal using two different microcontroller systems.

Project Features

• Two Microcontroller Systems: Utilizes EFM8LB12 and STM32L051 microcontrollers from different families to control the remote and the robot, respectively.
• Battery Operated: Both the robot and the controller are powered by batteries, making the system fully mobile.
• Remote Operation: Controlled via a remote that displays metal detection strength and includes a buzzer that beeps at frequencies corresponding to the metal strength detected.
• Metal Detection: Includes a metal detector capable of detecting various metals and their strengths using a Colpitts oscillator configuration.
• Autonomous Capabilities: Features an 'autonomous driving' mode where the robot can navigate predefined paths without manual control.

Hardware Components

• Robot:

  • STM32L051 microcontroller
  • JDY40 Radio
  • Motors, wheels, and chassis
  • Various sensors and actuators

• Remote:

  • EFM8LB12 microcontroller
  • JDY40 Radio
  • LCD display
  • Joystick for navigation

Software Description

The robot and remote are programmed in C. The software includes functionality for:

• Remote control of the robot's movement
• Real-time display of metal detection results
• Autonomous navigation based on pre-set conditions
