Hesai JT128

A compact, ultra-wide-field-of-view 128-channel 3D lidar from Hesai Technology aimed at robots.

The JT128 is the 128-channel model in Hesai Technology’s JT series of lidars, which also includes the JT64P and JT16. “Channel count” refers to the number of laser channels in the vertical direction — more channels means a denser point cloud. According to Hesai’s official specs, the JT128 has a 360°×189° field of view, covering more than a full hemisphere; it ranges to 40 m at 10% reflectivity, with a maximum of 60 m; it produces about 1.152 million points per second in single-return mode; and it measures 62.5 mm in diameter and 73 mm tall, weighs 265 g, and is rated IPX7. Traditional spinning lidars usually have a vertical field of view of only a few tens of degrees, which tends to leave blind spots when mounted on a robot; the JT series uses an ultra-wide vertical field of view to reduce these blind spots. Hesai’s website lists embodied AI robots, delivery robots, AGVs/AMRs, and cleaning robots among its applications, for mapping, localization, obstacle avoidance, and terrain sensing.
