COLLISION PREVENTION SYSTEM OF MOBILE ROBOT IN UNKNOWN ENVIRONMENT AND METHOD THEREOF

摘要

PURPOSE: A system and a method for preventing a collision of a movable robot is provided to improve driving safety as a collision prediction system confirms a region in which environmental changes such as damages of a road caused by a natural disaster and fog exist as a danger zone and provides intelligent driving information to a driver and the movable robot. CONSTITUTION: A system for preventing a collision of a movable robot (10) includes an inner sensor unit, an external sensor unit, and a control unit. The control unit is composed of a region route planning unit (11) and an entire-region route planning unit (12). The region route planning unit plans a region route plan for avoiding a collision with obstacles and a movable object based on driving information collected by the inner sensor unit. The entire route planning unit plans an entire route plan for controlling a drive of the movable robot according to geographical features and a weather condition.
