Description

SCOPE OF THE INVENTION

[0001] The present invention relates to an autonomous robot system specifically designed for search and rescue operations in hazardous environments. It combines advanced sensor technologies, artificial intelligence (AI), and real-time communication to locate survivors, assess environmental threats, and provide critical data to rescue teams. The invention is particularly suitable for natural disasters, industrial accidents, and other hazardous situations where human involvement poses a significant risk. BACKGROUND

[0002] Search and rescue operations in hazardous environments, such as disaster zones or accident scenes, often expose personnel to significant risks, such as structural instability, toxic gases, and poor visibility. Existing methods rely heavily on human intervention, resulting in delays and increased dangers for rescuers and survivors. The need for a robust, autonomous robot system capable of navigating these environments, identifying survivors, and transmitting information in real time is paramount. The present invention addresses these challenges by providing a robust, sensor-equipped robot that operates autonomously or semi-autonomously, minimizing risks and increasing rescue efficiency.
