Introduction

The objective of this project is to develop an autonomous mobile robot capable of assisting users through navigation, obstacle detection, environmental awareness, and remote monitoring. The robot integrates sensing, communication, embedded control, and web-based interfaces to create an intelligent and interactive platform. The system combines mechanical, electronic, and software components developed throughout Fab Academy.

System Architecture

Input Devices

The robot collects information from multiple sensors:

  • Ultrasonic sensor for obstacle detection
