PhD (Tsinghua University)
Dr. Jing Peng is a Postdoctoral Research Fellow in Design Robotics for Advanced Manufacturing at QUT. Her research interests include computer vision, robotics and pneumatic control.
Jing completed her BEng in Measurement, Control Technology and Instruments and her PhD in Mechanical Engineering at Tsinghua University. There she co-invented (with Prof. Xinchun Lu and Dewen Zhao) a conditioner for conditioning the polishing pad and they got a granted patent for that. The patent is cited by global market leaders, e.g. Siltronic AG, Fujikoshi Machinery. She designed and built a conditioner for chemical mechanical polishing and worked with her colleagues to build a fully automatic chemical mechanical polishing machine from scratch.
Her PhD thesis was on ultra-precision low-damage polishing and its mechanism for KDP crystals. KDP crystals are soft, brittle and deliquescent, yet to achieve high performances as frequency convertors in high power laser systems requires nanometer-scale roughness super-smooth surface and damage-free subsurface. To further investigate their mechanical properties she joined Prof. Liangchi Zhang’s group in Mechanical and Manufacturing Engineering at UNSW and they carried out nanoindentation tests with a conical diamond indenter and found the elastic-plastic deformation of KDP crystals under nanoindentation. Then she returned to Tsinghua and built the theoretical model for polishing and through lots of polishing tests achieved surface roughness of 0.62 nm for KDP by optimizing various machining conditions and slurry formulation.
After graduation she worked as a Post-doctoral Fellow in Surgical Robotics and Soft Robotics at the University of Hong Kong. In the surgical robot project she led, she co-invented (with Prof. Zheng Wang, Prof. Zhiqiang Chen and Prof. James Lam) arm units and surgery robot systems and they got a granted patent for that. Generations of surgical robot prototypes with 6mm diameter robot arm which is tiny enough to go through natural orifices yet dexterous with 6 precisely controlled inside body degrees of freedom plus one DOF of forceps and large output force to perform surgery were built by the project team. She also designed and fabricated soft actuators for a soft robotic manipulator project. The soft actuators are linear, light and pneumatically driven, with substantial deformation ratio and quasi-constant output force over a wide motion range.
