Autonomous disinfection robot with Robotic Arm for precision cleaning

Abstract

Hospital-acquired infections (HAIs) remain a major challenge to patient safety and healthcare efficiency. This project presents the design and implementation of an autonomous disinfection robot equipped with a 6-degree-of-freedom robotic arm for precision sanitization in healthcare environments. The robot integrates a LiDAR-based SLAM system for navigation, mecanum wheels for omnidirectional mobility, and an electrostatic spray system for targeted disinfection. A database-linked user interface allows authorized personnel to monitor, schedule, and control disinfection processes remotely. Simulation and prototype results confirm that the system effectively maps environments, avoids obstacles, and performs adaptive surface cleaning with minimal human intervention.
