Abstract: The ongoing need for enhanced hygiene and infection control, especially in the wake of global pandemics, has driven innovation in autonomous sanitization technologies. This survey paper explores the development and application of an Auto Sterilization Robot designed to autonomously disinfect environments such as hospitals, offices, schools, and public transport facilities. The robot integrates various technologies including UV-C light, chemical spraying systems, obstacle detection, and autonomous navigation using sensors and microcontrollers. The paper reviews existing solutions, compares key design methodologies, and evaluates performance metrics such as coverage efficiency, disinfection effectiveness, and energy consumption. Emphasis is placed on the role of automation in reducing human exposure to pathogens and improving the consistency of sterilization processes. The survey concludes by identifying current challenges and proposing future directions for improving autonomy, safety, and adaptability in sterilization robotics.
