About JT128

Hesai JT128 is a compact 128-channel three-dimensional lidar for robots and industrial equipment. Its rotating architecture covers a 360 by 189-degree hyper-hemispherical field of view, allowing one unit to observe ground-level, forward and overhead space around its mounting point. The sensor generates up to 1,152,000 points per second in single-return mode and reaches 60 metres under the stated maximum condition.

The cylindrical unit measures 62.5 millimetres in diameter by 73 millimetres high and weighs 265 grams. Hesai positions it for embodied systems, delivery and cleaning robots, AGVs, AMRs, spatial sensing and stationary installations. JT128 provides range measurements and point-cloud data to a host perception stack; mapping, localization, obstacle interpretation and motion decisions depend on the wider compute and software configuration.

Timeline

  • Hesai discloses new humanoid lidar orders and actuation shipments

    2026-08-18 - Market Signal - New robotics-lidar orders and JT128 adoption include Unitree, Robbyant, Galbot, Galaxea and Dexmal. After Kosmo prototype deliveries in July 2026, orders were secured from humanoid-robot companies including Galbot, with initial revenue expected in Q3. The robotic-actuation production line is operational, dexterous-hand module shipments are underway and Sharpa is an actuation-module customer.

  • ETH Zurich AutoBike completes autonomous campus ride with Hesai JT128 lidar

    2026-08-17 - Demonstration - Ten bachelor students developed the bicycle prototype over roughly nine months at ETH Zurich's Autonomous Systems Lab. The JT128 generated the 3D point cloud used for localisation, obstacle detection, free-space detection and route planning. The team reported a 75 percent success rate on the final day of testing and said further development would be required before public operation.

  • Hesai JT128 equips MOVIN TRACIN motion-capture system

    2026-01-05 - Capability - The partnership places Hesai’s JT128 mini hyper-hemispherical lidar inside MOVIN’s TRACIN motion-capture device, which tracks full-body movement without a conventional camera studio. JT128 provides a 360° × 189° field of view and 128-channel, low-latency point clouds, reducing setup time from about two hours to three minutes and limiting blind spots in tight spaces. Its active laser sensing works across lighting conditions and supports tracking sessions of up to 12 hours without drift, extending motion capture from specialist studios to homes, live venues and outdoor environments.

  • Hesai launches JT Series mini hyper-hemispherical 3D lidar for robotics at CES 2025

    2025-01-08 - Product Launch - Hesai launched the JT Series for robotics at CES 2025, including the JT16 and JT128 models. The company positioned the product line for robotics applications including humanoids, delivery robots, cleaning robots, AGVs, and industrial platforms. Hesai said the JT Series was designed around wide-field 3D perception, compact form factor, and close-range blind-spot reduction for robotics use cases.
