The goal of the system is to integrate powerful sensors and autonomous decision making within a compact 4wheel robot. The robot uses an ESP32 microcontroller as the central processing unit, an offline voice-recognition module for command-based operations, ultrasonic and IR sensors for obstacle detection and an L298N motor driver for motion control. The proposed system user assistance through smart control, allowing hands-free operation, remote command operation, person tracking, and safe obstacle handling. The design aims to support applications in household automation, personal assistance, indoor mobility, warehouse logistics and security patrolling. Experimental results indicate that the robot efficiently works between modes and reliably executes commands, ensuring intelligent and adaptive behavior suitable for real world environments.
This project is relevant in today’s technology where automation and intelligent robot assistants are increasingly used in homes, industries, healthcare and service sectors. Many existing robots depend on expensive components, cloud-based voice control, or high-complexity systems. This project provides a low-cost, offline, real-time smart robot that can perform multiple tasks without internet and external servers. The relevance also extends to educational, research and practical robotic development since it integrates multimode control and sensing.
1.2 Feasibility Study 1. Technical Feasibility: The system uses easily available hardware components ESP32, IR sensors, ultrasonic sensor, servo motor, motor driver which makes it ideal for implementation. Offline voice recognition reduces dependency on internet connection.
Key Words: Smart Robot, Voice Control, Human Following, Obstacle Avoidance, ESP32, Automation, Multi-Mode Robot
2. Economic Feasibility: All components used are low cost and easily available. The project can be built within a small budget, making it feasible for academic, hobby, and prototype applications.
1. INTRODUCTION
3. Operational Feasibility: The robot can operate indoors on flat surfaces and can shift between modes without requiring reprogramming. The offline voice module ensures stable performance even in any environments without network connection.
A smart robot is defined as robotic system capable of sensing, understanding and interacting with its surroundings to perform tasks automatic or semi-automatic. The concept of assistance refers to supporting human activities such as motion, object carrying, navigation and monitoring. Automation refers to enabling machines to perform tasks automatically with minimal human intervention. This project integrates all three concepts into a single robot that can be operated through multiple intelligent modes. The robot is designed to act as versatile assistant capable of responding to voice commands, following a human user, navigating indoors safely and operating under manual Bluetooth control. These features make the robot suitable for real life applications such as home automation, supporting elderly or disabled people, warehouse navigation, indoor delivery and security inspection.
