Guest Greeting Robot, Voice Recognition, Human–Robot Interaction, Autonomous Navigation, Embedded Artificial Intelligence (AI).

The Welcome Robot for Guest is an intelligent hospitality robot that automates the reception and assistance to guests in environments such as hotels, hospitals, corporate offices, shopping malls, airports and exhibition centers. The system combines embedded artificial intelligence, voice recognition, motion sensing and robotic movement to give visitors a natural and interactive experience. The robot reduces dependence on human reception staff and guarantees steady, effective and 24/7 hospitality services. The proposed system includes an AI Thinker VC02 voice recognition module, Arduino/NodeMCU controller, motion sensors, servo motors, and DC motors. The system detects the coming guests, identifies the voice commands, does the greeting gestures, and moves to the visitors. When a guest is detected, the controller processes sensor and voice input, chooses an appropriate greeting, and coordinates synchronised voice responses, arm waving, head movements, and robot navigation. After the interaction, the robot automatically goes back to standby mode, ready to help the next visitor. The hardware architecture consists of three servo motors for expressive gestures, four DC motors for movement, an L298N motor driver, a buck converter, dual 12V batteries, and a four-wheel robotic chassis. The software is written in Embedded C/C++ using Arduino IDE and it performs voice processing on the device, allowing fast and reliable operation without the need for an internet connection. Experimental evaluation demonstrates that the robot is able to reliably detect guests and respond to predefined voice commands, perform smooth gestures and navigate effectively in indoor environments. The modular design also allows for potential future upgrades such as multilingual voice interaction, face recognition, wireless remote management and multi-robot coordination. In general, the Welcome Robot proposed provides a cost effective, scalable and intelligent solution for modern automated reception systems, and significantly improves customer experience and reduces operational workload.
