Our LiDAR uses a custom-designed laser that separates 1064 nm and 532 nm wavelengths from a single source, with two dedicated receivers capturing each set of data independently. Inside the system, the linear laser beam is refracted at a 10-degree angle through a prism to enable circular scanning. An RF module is also integrated for real-time equipment status monitoring. From circuit board design to component selection, every part of this system was developed in-house by multiple institutions. As a result, we have successfully eliminated reliance on foreign technology.

Our in-vehicle monitoring solution applies VLM-powered indoor and outdoor cameras to deliver real-time driver and passenger awareness. By integrating AI models such as facial landmark and head pose detection, gaze tracking, object recognition, and human pose estimation, the system supports safety features like drowsiness detection, distraction monitoring, and surrounding object awareness. Optimized for automotive SoCs including Qualcomm, and running on QNX RTOS and Linux, our solution combines model compression, embedded optimization, and a streamlined development pipeline. This ensures reliable, low-latency performance tailored for next-generation connected and intelligent vehicles.

ORSKOREA’s centerless grinding machines ensure stable accuracy and durability without the need for chucks or centers. By allowing workpieces to rotate freely between the grinding and regulating wheels, they deliver high-efficiency and uniform machining for shafts, pins, housings, and other cylindrical components used in aerospace, defense, and advanced automotive systems. Key Advantages • High productivity through fast, efficient multi-part processing • ±2μm precision and long-term repeatability • Versatility to handle components from small to large sizes • Hydrostatic slides and spindles minimizing heat and vibration • Proven stability for high-value part manufacturing such as engine components, battery cases, and optical housings By combining productivity, accuracy, and reliability, ORSKOREA’s centerless grinders significantly enhance competitiveness in both defense and civilian applications.
