VIoT: A Voice and IoT Controlled Unmanned Automated Vehicle

VIoT, a Voice and IoT Controlled Unmanned Automated Vehicle (UAV), pioneers a blend of Voice, IoT, and Bluetooth technologies to redefine remote-controlled robotics. Powered by Rock Pi 3a and an Android app, users seamlessly control the car using Bengali voice commands transmitted through IoT for long-range communication. It also uses Bluetooth for short-range operations if the vehicle is within approximately 20 meters of range from the controlling app. The dual-mode control mechanism offers flexibility, allowing users to steer the robotic car through the Android app effortlessly. Leveraging Google Speech Recognition API for Bengali voice input, this paper establishes a new standard for user-friendly robotic interfaces. Using WebSocket instead of an actual database like Firebase as the medium of data passing for IoT communications significantly solves latency problems. The comprehensive hardware setup includes Rock Pi 3a, L293D motor driver, and basic components, setting a milestone in human-robot interaction and expanding adaptability across various applications.
