Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of inspection robots, and more particularly to collision-prevention robots based on radar technology. [Background technology]
[0002] In industrial applications, inspection robots are widely used in equipment inspection and environmental monitoring. For example, in the power industry, inspection robots can remotely monitor substations and power lines, quickly detecting and eliminating potential breakdowns. Similarly, in the petrochemical industry, inspection robots can inspect equipment and monitor hazardous chemicals in hazardous environments, reducing the safety risks of manual inspections. Furthermore, intelligent inspection robots are highly tolerant of high and low temperatures and corrosive environments, further expanding their application range.
[0003] In commercial environments such as department stores, office buildings, and residential areas, safety patrol robots play an important security role. They can operate along predefined patrol lines, providing 24 / 7 security patrols. By linking with a surveillance system, patrol robots can collect real-time video and audio information, intelligently analyze and identify abnormal behavior, and promptly notify security personnel to handle emergencies. Patrol robots can also be integrated with firefighting systems to detect harmful gases in the air and changes in temperature and humidity, providing timely alerts for emergencies such as fires.
[0004] In the field of public security, patrol robots are gradually becoming an important guarantee for public safety. For example, in public places with high traffic volumes, such as train stations and airports, patrol robots can not only perform regular patrol tasks, but also, when combined with facial recognition systems, assist police in identity verification and target tracking. Especially at large-scale events, patrol robots can perform wide-area, real-time monitoring, thereby improving the efficiency and effectiveness of public security management.
[0005] Collision prevention is one of the most basic and important capabilities of a patrol robot. Using sensors and intelligent algorithms, patrol robots can sense changes in the surrounding environment in real time and avoid obstacles, both moving and stationary, in a timely manner. Laser radar, ultrasonic sensors, and infrared sensors enable robots to operate in complex indoor and outdoor environments, providing the foundation for real-time path planning and obstacle avoidance. While conventional radar-based collision prevention robots are relatively mature, their radar configurations are often single-panel and can only detect targets in one direction, resulting in large detection blind spots. Furthermore, typical patrol robots have a fixed body structure, lack adjustment capabilities, and are therefore limited in their capabilities. Summary of the Invention [Means for solving the problem]
