This presentation will focus on the development of robotic neuro surgery system. The system, called NEUROBOT, was built with a parallel-kinematics machine (PKM) structure. The NEUROBOT aims to assist neuro-surgeons in drilling cavities on the skull base, which allow access to tumors deeply seated in brain areas. With such a system, the neuro- and ENT- surgeons could significantly reduce operation time from current 5 to 8 hours to less than 2 hours. The modules that comprise the system will be introduced. A base-tool calibration method utilizing an optical tracking system will be derived and the experimental results will be discussed. Moreover, the presentation will outline some novel designs of robotic mechanical system, including a pitch-roll wrist and 4 degree-of-freedom parallel manipulators. Applications of these novel mechanism in the manufacturing industry will be discussed.

Dr. Shaoping Bai received the B.Sc degree in Precision Instrument Engineering from Harbin Institute of Technology, Harbin, China, the M.Eng degree in Machine Building from Tsinghua University, China, and the Ph.D. degree in Robotics in Nanyang Technological University, Singapore, in 1988, 1993, and 2001, respectively. Currently, Dr. Bai is a postdoctoral fellows of the center of intelligent machine, McGill University, Canada. Dr. Bai has worked for many years in the aerospace industry and IT manufacturing. His research interests include legged locomotion, parallel manipulators, mechanism design and optimization, medical robotics, and manufacturing automation.
