Latest Patents

Lee’s listed patents address practical challenges in automated handling and robotic vision.

- **Picking device.** This invention describes a device for picking up materials using negative pressure. A vacuum source supplies suction through air channels in a main body to multiple movable picking assemblies. Each assembly includes a picking piece, a moving piece, and a blocking piece, allowing the airflow to be controlled as the components move.

- **Hand-eye calibration method and hand-eye calibration device for robot arm.** This invention presents a method and device for calibrating the relationship between a robot arm, its tool, a camera, and a target object. The method updates mapping relationships to reduce the difference between the target’s position in a camera image and the tool’s position, then outputs calibrated relationships when the error converges and meets a scale threshold.

Career Highlights

Lee’s patent work spans two complementary areas of automation: vacuum-based material handling and the calibration of robotic systems using camera data. Together, these inventions address how robots can pick up materials and align their tools with objects identified through vision.
