How SCANOLOGY’s 6D Pose Tracking System Turns Robots into “High-Precision Experts”

The 2025 World Robot Conference has sparked a wave of excitement around robotics. While humanoid robots capture the spotlight, industrial robots are quietly transforming traditional manufacturing toward flexibility and intelligence. Thanks to their multi-joint versatility, industrial robots have become essential for multi-product, small-batch, and customized production.

However, as industries demand higher precision for tasks like complex surface machining and high-accuracy assembly, limitations in absolute positioning and dynamic stability of industrial robots are becoming more apparent. Load disturbances, joint errors, and cumulative inaccuracies have created a “precision anxiety” in high-end manufacturing.

Precision Inspection, Rapid Calibration, Dynamic Compensation

SCANOLOGY’s 6D Pose Tracking System addresses these challenges with robust performance: 100Hz high-frequency tracking and an absolute spatial accuracy of 0.049mm (3.5 m). The system enables precise inspection, fast calibration, and real-time compensation, turning industrial robots into “high-precision experts” and significantly enhancing production efficiency and product quality.

The 6D Pose Tracking System integrates trackers, custom adapters, probes, and analysis software. Utilizing innovative stereo vision and optical tracking technology, it breaks through the limits of traditional 3D coordinate measurement, capturing high-precision six-degree-of-freedom (6-DOF) data of target objects in real time.

Additionally, the system incorporates dynamic compensation algorithms to provide accurate feedback on pose deviations, even in vibrating or interference-prone environments, boosting robots’ absolute positioning accuracy.

Strengthening Precision for Your Robots

Manual TCP calibration has long been a pain point in manufacturing lines, particularly in industries like automotive. For example, in highly automated body-in-white welding lines, a single robotic welding station may require multiple types of welding guns for 360° operations. Every tool change traditionally requires a full TCP recalibration—a tedious, time-consuming process prone to human error.

The SCANOLOGY’s 6D Pose Tracking System leverages 3D scanning to quickly capture the end tool’s 3D data, identify key features, and calculate the robot’s TCP accurately. It allows rapid multi-tool measurement without stopping the robot, making calibration faster, simpler, and more reliable than traditional methods.

Accurate robot positioning is essential for processing complex parts and enabling virtual simulation on automated production lines. The 6D Pose Tracking System provides a complete view of the workspace, measuring and calculating the positional relationship between robots and fixtures with precision. Real-time absolute coordinates of the robot’s end tool serve as a reliable foundation for simulation and automated operations.

In precision manufacturing, robots follow predefined paths. Even minor deviations due to low absolute accuracy or load changes can cause critical errors. The 6D Pose Tracking System acts as a “real-time navigator,” using optical tracking to capture the robot’s absolute TCP coordinates. By comparing actual positions with theoretical ones, the system calculates compensation values, allowing robots to dynamically adjust paths during welding, grinding, drilling, and other operations. This real-time correction mitigates load disturbances and enhances yield.

Currently, SCANTECH’s 6D Pose Tracking System is empowering industrial robots across multiple sectors. Looking ahead, it will continue to extend high-precision capabilities to more advanced manufacturing environments.
