Wireless Control System for A Smart Robot

This paper delineates the development of an Android mobile application tailored for manual control of a robot vehicle via wireless Bluetooth technology. The application prioritizes user interaction through both visual and voice-based commands, offering a versatile control interface. Through the graphical interface, users can actively monitor the robot’s proximity to obstacles, facilitated by an integrated ultrasonic sensor positioned at the robot’s front. The necessity for a mobile robot prototype based on a differential gear system was paramount to the application’s evolution. The project’s core objective lies in achieving precise control through voice commands, employing an Android application integrated with a microcontroller. The seamless connection between the Android app and the robot vehicle is established through Bluetooth technology, granting users control via on-screen buttons or spoken commands. A preliminary preparatory session is integral to ensuring the smooth operation of the robot, with a dedicated code employed for instructing the controller effectively. This innovative amalgamation of innovative technology and user-friendly control mechanisms holds promising applications across various domains, from industrial automation to assistive technologies, underscoring the project’s potential for real-world impact.
