GUJ50(A) is the first 32-line mechanical intrinsically safe laser radar sensor in China, specially developed for high-precision measurement in mines. The housing and core are integrated and encapsulated, providing superior heat dissipation performance and adaptability to strong vibration environments. The single-channel intrinsically safe power supply is more flexible and easy to use, and it is widely applied in underground autonomous driving, robot navigation, surveying and mapping, and other scenarios. It provides an efficient and precise environmental perception solution for underground 3D modeling, SLAM positioning, obstacle perception, and other research.
