Handgesture And Voice Control 4 – Wheel Robot

Abstract

Human–robot interaction has become an essential area of research in modern robotics, particularly in systems that require intuitive and user-friendly control mechanisms. This paper presents the design and development of a four-wheel robotic platform controlled through hand gestures and voice commands, enabling natural and wireless interaction between the user and the robot. The proposed system aims to replace conventional manual controllers with more accessible and interactive control methods.The robotic platform is built around the Arduino Uno microcontroller, which acts as the main processing unit. Gesture inputs and voice commands are generated using an Android-based mobile application and transmitted wirelessly through an HC-05 Bluetooth module. The Arduino interprets the received commands and drives the robot accordingly through an L293D motor driver, which controls four DC motors connected to the wheels. Based on the commands received, the robot performs basic directional movements including forward, backward, left, right, and stop with minimal delay and reliable accuracy.
