The World’s First “Thousand-Beam” Long-Range Digital LiDAR
Product Specifications
EM4 is the first long-range digital LiDAR on the EM platform, marking the beginning of the “thousand-beam” era in automotive LiDAR technology. Incorporating RoboSense’s new digital architecture, crosstalk elimination, all-condition optical signal processing, and lossless data compression technologies, EM4 delivers groundbreaking performance with up to 1080 beams, a maximum detection range of 600m, and a point rate of 25.92 million points per second.
With its ability to provide 1080P high-definition 3D perception, EM4 redefines the standards for intelligent vehicles, leading L3 and above autonomous driving technologies into a new era of development.
As the digital automotive LiDAR with the longest detection range on the market, EM4 offers a 300m@10% ranging capability and a maximum range of 600m. This extends the response time of intelligent driving systems by up to 70%*, enabling more confident and precise decision-making. EM4 delivers unparalleled safety and comfort for users, redefining the driving experience.
EM4 is the world’s first 1080-beam automotive LiDAR, delivering 1080P high-definition 3D perception for vehicles. With an outstanding angular resolution of up to 0.050°×0.025° and ultra-long-range detection capabilities, EM4 precisely identifies distant small objects such as tires, traffic cones, and cardboard boxes. It empowers intelligent driving systems to push safety boundaries beyond NHTSA active safety standards*, providing ultimate assurance for advanced intelligent driving and fully autonomous driving systems.
Powered by cutting-edge proprietary technologies, EM4 achieves comprehensive upgrades in high-reflection blooming suppression, noise reduction in rain, fog, and dust, as well as contamination resistance. These advancements enable autonomous driving systems to achieve clear and precise environmental perception in all scenarios and conditions.
EM4 adopts RoboSense’s new digital architecture and equipped with SPAD-SoC chip and VCSEL chip. This innovative design enables high-sensitivity digital detection, significantly simplifying signal processing and transmission pathways. The result is lossless information flow and the generation of high-quality point cloud outputs.
