Frequently Asked Questions
What is the HESAI QT128 LiDAR used for?
The HESAI QT128 is an automotive grade 128 channel 360° ultra wide view short range LiDAR designed for close range perception, blind spot coverage, robotaxi, robotrucking, stationary applications, warehousing, and logistics. It is especially useful where vehicles or machines need to detect objects extremely close to the sensor.
Why is it important for blind spot detection?
360° horizontal coverage with about a 105° vertical field of view lets it clearly detect cars, pedestrians, and small animals at extremely close range — well suited for near field safety perception around autonomous platforms.
Is this a long range or short range LiDAR?
It is a short range LiDAR. Range spans approximately 0.05 m to 50 m, with around 20 m detection at 10 percent reflectivity, making it ideal for ultra wide view short range perception.
What makes the 105° vertical field of view useful?
It lets the sensor see both high and low objects around it, not only objects at bumper or floor level — helping cover near field blind spots in robotaxi, robotrucking, warehouse, and stationary safety environments.
Can it detect objects very close to the sensor?
Yes. With a minimum detection range of around 0.05 m, it detects nearby pedestrians, vehicles, road cones, small animals, pallets, forklifts, and other obstacles that may be too close for long range LiDAR sensors to capture effectively.
Why is the HESAI QT128 useful for robotaxi and robotrucking?
It fills the close range perception gap around autonomous vehicles. Long range LiDAR detects distant objects, while the QT128 provides ultra wide near field awareness around the vehicle body.
Is it suitable for warehouse and logistics automation?
Yes. Compact design, high vertical coverage, and 360° sensing make it relevant for close range object detection around automated vehicles, loading zones, docks, industrial corridors, and stationary monitoring points.
How compact is the design?
Dimensions are around Φ87 mm in diameter and 83.9 mm in height, with a weight of approximately 700 g depending on configuration — compact for a 128 channel 360° ultra wide LiDAR.
Is it automotive grade?
Yes. It is designed for automotive grade and mass production use, with extensive validation including UV aging, high temperature, IP6K7 and IP6K9K protection, mechanical shock, salt spray, thermal shock with water splash, low temperature wakeup, humid heat cycling, vibration with thermal cycling, and electrical and electronic testing.
When should a team choose the HESAI QT128?
Choose the QT128 when you need 360° close range perception, wide vertical blind spot coverage, compact automotive grade design, and reliable near field object detection — most relevant for robotaxi, robotrucking, stationary monitoring, warehouse automation, and logistics use cases where detecting close objects matters more than ultra long distance sensing.
