Hesai’s new OT128 360° lidar sensor is designed for the likes of L4 autonomous driving, industrial robotics, smart ports, and ADAS development. The OT128 pivots from traditional mechanical rotary designs, instead using chip-based architecture for the transceiver modules. This ensures high performance, automotive-grade reliability, and the ability to be mass-produced efficiently.
This is the first time Hesai has applied their VCSEL+SiPM transceiver module to a 360° mechanical lidar, with over 95 per cent of its core components shared with the existing AT128 lidar. The OT128 has 66 per cent fewer components and a 95-per-cent decrease in core manufacturing steps, which means faster production. It offers 360° rotative scanning without the need for multiple units, and a mature, proven design for sturdy reliability.
Performance stats include detection range of up to 230 meters at 10 per cent reflectivity, 3.45 million points per second, and 0.1° angular resolution. The OT128 is already in mass production at Hesai’s factory, and companies including DeepRoute, WeRide, and Westwell have selected it for their projects.
DVN comment
Lidar leader Hesai showed their advanced OT128 lidar at IAA Transportation in Hannover. The OT128 seems the most mature 360° long-range lidar available; surely it will greatly improve AVs’ comprehensive sensing capabilities.
