Latest Patents

Chang is credited with 1 patent: “One-shot robust visual-force robotic servoing for novel object insertion with 6-DoF tracking.” The invention describes a system and method for automated object assembly, including insertion and part reorientation using a robotic arm. It estimates the end-effector and object poses from a task-demonstration image, then uses RGB-D cameras and six-degrees-of-freedom visual tracking to track and grasp the object. During movement, the system repeatedly adjusts the end-effector to align the object with its pre-assembly pose, then uses an impedance-control-based search to complete insertion into a receptacle.

Career Highlights

Chang’s listed patent reflects work on combining visual tracking and force-aware robotic control to address assembly tasks involving unfamiliar objects. The approach is designed to support precise alignment and insertion through iterative pose tracking and a final search procedure.

Collaborations

The patent lists Siddarth Jain and Abdeslam Boularias among Chang’s coworkers. The work is associated with Mitsubishi Electric Research Laboratories, Inc.

Conclusion

Haonan Chang’s patent highlights an approach to robotic assembly that integrates six-degrees-of-freedom visual tracking with impedance-based insertion, supporting the precise handling of novel objects.
