This project aims to improve the dexterity available to a robot-assisted minimally invasive surgery.  Specifically, the project investigates the role of magnetic device and magnetic linkages to actuate surgical devices across the abdominal wall for abdominal surgery, hence the term "Local Magnetic Actuation (LMA)". 

This research is carried out in collaboration with Vanderbilt University (Prof. Pietro Valdastri) and St Vincent's Hospital (Dr Dhan Thiruchelvam).
