ShanghaiJune 4, 2026 /PRNewswire/ — Imagine a scene: a lawn-mowing robot is diligently working in a yard when suddenly a heavy rain pours down, shrouding everything in mist. The next second, it starts bumping around like a “headless fly”—this is the real dilemma many robots face today.
How can this dilemma be resolved? Quectel, together with Ruixin Guanyuan and Andar Technologies, has provided the answer—the three parties have jointly launched a domestically produced single-chip 8-transmit 8-receive (8T8R) ROS-SLAM millimeter-wave radar for the robotics field, breaking through the industry bottleneck of traditional 3-transmit 4-receive chips, which suffer from sparse point clouds and struggle to support fine mapping and obstacle avoidance. This allows robots to maintain stable perception and precise movement even in harsh environments such as dust, rain, snow, and frost.
Why do robots need such a “radar core”? The reason is simple: traditional robots rely too heavily on optical perception solutions (such as depth cameras and LiDAR). Once faced with complex environments, optical signals are prone to attenuation or failure. Millimeter-wave radar, leveraging the penetrating properties of electromagnetic waves, precisely fills this gap.
One Chip, Tenfold Performance
Unlike traditional vision and LiDAR, millimeter-wave radar uses electromagnetic waves for detection, with longer wavelengths and stronger penetration, easily cutting through obstructions caused by complex environments.
Quectel, Ruixin Guanyuan, and Andar Technologies have deeply recognized this advantage. The released domestically produced single-chip 8T8R ROS-SLAM millimeter-wave radar achieves multiple performance leaps:
1. Enhanced Perception Performance
Compared to the traditional 3T4R architecture, the 8T8R architecture delivers a comprehensive performance improvement of over 10 times (based on internal tests at Quectel’s lab), providing stronger data support for mapping in complex environments.
2. Long-Range High-Precision Imaging
Effective perception range reaches 50 meters, with ultra-high angular resolution of 1.5° horizontally and 2.5° vertically, achieving imaging quality close to LiDAR and vividly reproducing 3D environmental contours.
3. All-Weather Penetration Capability
Unaffected by interference from grass, sand, mud, frost, etc., it maintains stable perception even in harsh environments.
4. Intelligent Filtering and Recognition
Effectively filters out static obstacles and environmental noise, providing clean and reliable decision-making data for path planning and obstacle avoidance.
8T8R 4D Imaging Radar: Dual Core for Perception and Decision-Making
Lawn mowers are a key application scenario for robots. For efficient operation, perception capabilities must be robust. The 8T8R 4D imaging millimeter-wave radar is not a simple “copy-paste” automotive solution with a new shell; it has been deeply optimized specifically for lawn-mowing scenarios, achieving dual breakthroughs in hardware architecture and algorithm levels.
Starting with hardware. The 8T8R large array design achieves high-performance 4D imaging within a compact volume, significantly improving horizontal angular resolution. At a distance of 2 meters, it can accurately distinguish objects spaced just 15 centimeters apart, allowing the lawn mower to bid farewell to “blind cutting.” It also supports height measurement, identifying height-limited obstacles like barbecue grills and swings, enhancing safety during passage.
Moving to algorithms. The jointly developed proprietary solution tackles two major industry pain points:
1. Cold Start Challenge
Traditional radars have sparse point clouds when stationary, often causing confusion at startup. The new solution integrates deep learning, using historical point cloud information for real-time inference, enabling perception from a zero-speed start.
2. Material Recognition
Relying on an AI classification model trained with over 100,000 samples, it can accurately distinguish 12 common material types, including metal, plastic, and vegetation, and clearly identify boundaries between grass and hard ground. This allows the lawn-mowing robot to truly “understand and master cutting.”
Additionally, in areas with weak GNSS signals, such as yard corners or under tree shade, this radar provides stable, low-drift positioning capabilities through a proprietary millimeter-wave point cloud inference positioning algorithm—enabling precise navigation without relying on satellites.
Powerful Collaboration: Building a New Industry Ecosystem
The birth of a hardcore product relies on deep synergy among core forces in the industrial chain. The successful launch of this 8T8R millimeter-wave radar is a significant result of complementary advantages and technological integration among Quectel, Ruixin Guanyuan, and Andar Technologies.
Among them, Quectel, with its mature hardware engineering capabilities, stringent quality control, and mass production experience, lays a solid foundation for the product’s large-scale commercialization; Ruixin Guanyuan provides core solution support with its professional SLAM algorithms and robot millimeter-wave radar product development expertise; Andar Technologies, starting from the underlying chip, endows the radar with powerful perception capabilities.
Through this tripartite collaboration, an “industrial eye” has been created for robots, enabling them to operate fearlessly in complex environments, pushing embodied intelligence beyond environmental limits, and accelerating the domestic advancement of the robotics industry.
In the future, Quectel will continue to partner with ecosystem players, leveraging technological innovation to solve industry pain points, enabling precise robot perception, and driving embodied intelligence to truly serve thousands of industries.
