AI-Driven Humanoid Robot in the Service Sector

A multilingual humanoid receptionist robot has been developed to assist patients and simplify routine administrative tasks in hospital environments. The system interacts with users in multiple languages by employing natural language processing and speech recognition techniques. A Raspberry Pi acts as the primary processing unit, while an Arduino microcontroller controls motor and servo operations for movement and gesture execution. To ensure clear and reliable speech input in noisy surroundings, active noise cancellation is applied during voice capture. The robot is equipped with obstacle detection sensors that enable safe and autonomous navigation. In addition, it provides basic medicine-related guidance and supports doctor–patient communication through API- based integration. This system demonstrates the practical application of artificial intelligence and robotics in healthcare automation, leading to improved efficiency, accessibility, and overall user experience.
