According to a report in Wednesday’s Science and Technology Innovation Board Daily, Baidu’s autonomous driving mobility service platform, Luobo Express, may be the first to implement a thousand-line LiDAR system in a vehicle. The exclusive pre-installation supplier has been secured by RoboSense, which will provide its next-generation pre-installed Robotaxi models with a “thousand-line EM4 + all-solid-state blind spot E1” digital LiDAR combination.
Another industry insider analyzed that, “‘High line count + digitalization’ is the main development direction of the industry at present. The demand for LiDAR has entered the ‘thousand-line’ era, and the combination of ‘high line count main LiDAR + all-solid-state blind spot filling’ may become a necessity for autonomous driving (L3/L4) vehicles.”
In early 2025, RoboSense released the world’s first mass-producible “thousand-line” ultra-long-range digital LiDAR, the EM4. Based on a platform-based design, the EM4 supports customizable technical solutions with 520 lines, 720 lines, 1080 lines, and 2160 lines. Currently, the custom-developed 520-line version has been mass-produced and applied in multiple models, including the Zhiji LS9, Zhiji LS6, and Jike 9X.
Taking the 1080-line version as an example, the EM4 boasts a maximum angular resolution of 0.050° × 0.025° and an ultra-long range of 600 meters, capable of clearly detecting targets such as tires at 180 meters away, black cardboard boxes at 250 meters away, and traffic cones within 300 meters. Compared to current mainstream LiDAR products, the EM4 can significantly reduce system response time. Increased by 70%.
When faced with smaller obstacles, such as stones, small cardboard boxes, and roadside debris, which are close to the height of a car chassis, the EM4 520 line customized version also obtained clear echo characteristics at a distance of about 130 meters in actual tests, using a 13×17 cm cardboard box as the target object.
