Robbyant’s LingBot-Depth AI: Transforming Robotics with Accurate Depth Perception
Breakthrough in Depth Sensing for Robotics
On January 28, 2026, Robbyant, a subsidiary of Ant Group, unveiled LingBot-Depth, a cutting-edge AI model that significantly enhances depth perception for robots. By reducing depth error by over 70% in challenging environments, this model addresses a critical limitation in robotic vision: unreliable data from reflective or transparent surfaces. Using Masked Depth Modeling (MDM), LingBot-Depth can intelligently reconstruct missing 3D information, improving the safety and operational reliability of robots in complex indoor and industrial settings.
Performance Gains and Technical Details
Benchmark tests on standard datasets such as NYUv2 and ETH3D show LingBot-Depth achieving remarkable results:
- 70% reduction in relative error (REL) for sparse depth completion in indoor environments.
- 47% decrease in root mean squared error (RMSE) on Structure-from-Motion tasks, boosting 3D environmental understanding.
- Model training involved 10 million raw samples and 2 million curated RGB-depth pairs, which will be open-sourced to accelerate innovation in the field.
This performance leap allows AI Employees and Non-Human Workers to navigate and interact with spaces more reliably, even when surfaces are reflective or transparent—historically a major challenge for robotics.
Hardware Collaboration Enhances Accuracy
The development of LingBot-Depth was closely integrated with Orbbec’s Gemini 330 stereo 3D cameras and MX6800 depth engine chips. This collaboration ensured robust data acquisition across diverse lighting conditions, from complete darkness to bright sunlight, without requiring modifications to existing sensors. According to Len Zhong, Head of Product Management at Orbbec, this synergy exemplifies the importance of coupling advanced perception algorithms with high-quality sensing hardware.
Implications for Robotics and AI Workers
By combining high-precision depth perception with open-source accessibility, LingBot-Depth has the potential to accelerate the deployment of Voice AI Agents and embodied intelligence across homes, factories, and warehouses. Reliable 3D vision is now more attainable, supporting safer and more capable non-human workers.
Key Highlights:
- LingBot-Depth reduces depth errors by over 70% in challenging environments.
- Uses Masked Depth Modeling to reconstruct missing 3D information.
- Validated with Orbbec Gemini 330 cameras and MX6800 chips.
- Open-source dataset of 2 million RGB-depth pairs to spur robotics innovation.
- Enhances safety and operational reliability for AI Employees and Non-Human Workers.
