Abstract
A sensor duplexing apparatus and method are provided for a mobile robot to enhance obstacle detection reliability and ensure functional safety. The apparatus includes multiple sensors, logic boards, and a control unit that dynamically selects and compares sensor outputs within predefined duplexing areas. If inconsistencies are detected, the system identifies faulty sensors and applies fault recovery or correction procedures. By duplicating critical sensing functions and enabling real-time error handling, the system satisfies safety performance requirements such as performance level d (PL-d), allowing stable and reliable robot operation even under sensor failure conditions.
