Biography

Dr. Xuefeng Wang’s research of mechanical design and medical robotics are:

  • 1) a remotely-actuated MRI-compatible neurosurgical robotic system has been developed and under testing, where a creative switching mechanism has been invented to reduce the number of ultrasonic motors by half;
  • 2) a bionic hand exoskeleton with a new concept to mimic tendon routing in real hands is designed and in prototyping;
  • 3) a micro soft robotic guidewire is designed and its notched-joint bending behavior is modelled;
  • 4) a SMA-actuated multi-segment guidewire is fabricated and under testing for the use of cardiac surgery in MRI room; and
  • 5) a scalable infinitely variable transmission, or IVT, using an innovative mechanism to change its speed ratio continuously, which can effectively improve mechanical efficiency in robotic and vehicle applications. A robust nonlinear control method of the IVT was developed to achieve fast and stable speed-ratio tracking.

In research of nonlinear dynamics, Wang developed a modified incremental harmonic balance method to increase computational speed by a hundred times as well as to reduce algorithm complexity in solving both lumped and distributed systems with strong nonlinearity and multiple delays. This method has been successfully used in optimization of belt-drive systems and vibration analysis of gear systems.
