<p>The new Robotaxi model features four Hesai AT128 lidar sensors, playing a central role in the vehicle’s 360° blind-spot-free perception system. With an industry-leading 1200×128 resolution, the AT128 captures 1.53 million points of data per second, offering detailed and reliable perception in complex and dynamic driving environments. Its long detection range of up to 200 meters, and 120° field of view enable early detection of obstacles, significantly enhancing safety in urban and highway scenarios. The Robotaxi integrates 33 sensors in total, using a heterogeneous sensor fusion architecture to deliver real-time, 360° situational awareness. The deployment of four AT128 lidar sensors enhances depth perception, ensuring safe navigation through complex traffic environments.</p>
