Title: The Innovative Contributions of Chi-Keng Tsai
Introduction
Chi-Keng Tsai is a prominent inventor based in Bloomfield Hills, MI (US). He has made significant contributions to the field of robotics, holding a total of 10 patents. His work focuses on enhancing robotic capabilities, particularly in grasp generation and motion planning.
Latest Patents
One of his latest patents is titled "Region-based grasp generation." This technique involves a region-based robotic grasp generation method for machine tending or bin picking applications. The process utilizes part and gripper geometry as inputs, typically sourced from CAD files, along with gripper kinematics. A human user defines target grasp regions on the part using a graphical user interface that displays the part geometry. The optimization solver computes multiple quality grasps for each target region, ensuring stable surface contact and avoiding part-gripper interference. These computed grasps are stored in a grasp database for use in actual bin picking operations.
Another notable patent is the "Method of robot dynamic motion planning and control." This method provides a system for motion planning for robots with a redundant degree of freedom. It computes a collision avoidance motion plan without artificially constraining the extra degree of freedom. The planning is formulated as a quadratic programming optimization calculation, which is efficient enough to compute the motion plan in real time during each robot control cycle. The objective function includes minimizing path deviation and ensuring clearance from obstacles.
