The Robotaxi, a cutting-edge autonomous vehicle developed jointly by Didi Autonomous Driving and GAC Aion, has set a new benchmark for the autonomous vehicle industry with the integration of Hesai Group’s AT128 long-range automotive LiDAR system.

A Breakthrough in Autonomous Vehicle Technology

The AT128 long-range LiDAR system is a significant advancement in the field of autonomous driving, providing a 360° blind-spot-free perception system and delivering real-time, 360° situational awareness to the vehicle.

• The AT128 supports obstacle detection at ranges up to 200m and provides a 120° field of view, enhancing vehicle safety in both urban and highway environments.
• The system delivers a resolution of 1200×128, capturing 1.53 million data points per second.

The Robotaxi model features four AT128 lidar sensors, which work together to provide a comprehensive view of the surroundings and enhance the vehicle’s safety features.

The Robotaxi’s use of Hesai’s AT128 LiDAR system is a significant milestone in the development of autonomous vehicles, providing a robust and reliable solution for L4 autonomous driving. The vehicle integrates GAC Aion’s safety redundancy platform with Didi’s hardware upgrades and autonomous driving software stack, offering a fully developed L4 autonomous driving solution. The Robotaxi is set to enter mass production this year, with initial deployments expected to begin in 2026. Hesai Group’s co-founder and CEO, David Li, has emphasized the importance of the collaboration between Hesai, Didi Autonomous Driving, and GAC Aion: “Our collaboration exemplifies the powerful synergy between advanced lidar innovation and full-stack autonomous driving systems. It demonstrates what’s possible when cutting-edge lidar technology meets sophisticated autonomous driving systems to transform how people move through the world.”
The Robotaxi’s success is a testament to the advancements being made in the field of autonomous driving, and its integration with Hesai’s AT128 LiDAR system sets a new standard for the industry.

Real-Time Situational Awareness

The Robotaxi’s 360° blind-spot-free perception system, enabled by the AT128 LiDAR sensors, provides real-time, 360° situational awareness to the vehicle. The system uses a total of 33 sensors integrated into a heterogeneous sensor fusion architecture to achieve real-time, 360° situational awareness. This allows the vehicle to detect and respond to its surroundings in real-time, enhancing its safety features and overall performance.

Enhancing Vehicle Safety

The AT128 supports obstacle detection at ranges up to 200m, providing a 120° field of view that enhances vehicle safety in both urban and highway environments. This advanced LiDAR system enables the vehicle to detect obstacles and respond accordingly, reducing the risk of accidents and improving overall safety. The Robotaxi model is equipped with four AT128 lidar sensors, which work together to provide a comprehensive view of the surroundings and enhance the vehicle’s safety features. The Robotaxi’s advanced safety features make it an attractive option for autonomous vehicle manufacturers and fleets, providing a reliable and effective solution for L4 autonomous driving.
