Gesture Control Robot using Arduino Lilypad

This paper presents the design and implementation of a gesture-controlled robot for applications, utilizing the Arduino Lilypad microcontroller. The proposed system allows users to control movements through hand gestures, providing an intuitive and efficient means of human-machine interaction. The gesture detection mechanism is built around the ADXL335 accelerometer, which interprets hand tilt and motion. Wireless communication between the gesture recognition unit is established via an RF433 module, ensuring seamless data transmission over a distance. The system employs an HT12 encoder and decoder pair to encode and transmit gesture commands to the motor controller. The motor driver, L293-DNE, is responsible for translating the received signals into movement, effectively managing the direction and speed of the robot. The system is powered by a 9V battery, regulated to ensure operational stability and prevent voltage fluctuations that could impact performance. This gesture-controlled system is designed to improve user convenience, particularly in retail and logistics environments where hands-free operation can streamline processes. The paper discusses the performance of the system in terms of wireless communication reliability, gesture recognition accuracy, and mechanical response, while addressing challenges such as signal interference and power management. Potential solutions to these challenges are also explored to enhance system robustness.
