Research project:

Traditional open surgery requires a large opening, which causes additional injury while gaining access to the          surgical region. Thus laparoscopy, a minimally invasive surgery, performed with long tools inserted through small incisions, has become the choice of interventions for many commonly performed open surgeries.

A new approach to laparoscopy involves inserting a miniature surgery robot entirely into the patient. This research aims to design, model and control a novel hybrid propulsion system for in-vivo inspections and surgical assistance.

Hybrid Robot Design 3

As a part of the project a 1D (one dimensional) capsubot (capsule robot) and a 2D (two dimensional) capsubot are designed and implemented. Two novel acceleration profiles are proposed for the inner mass (internal moving part) of the capsubot and implemented in the developed capsubots. A significant feature of the capsubot is that it has no external moving parts (i.e. legless, wheel-less, and trackless) whereas a conventional robot has legs, tracks and/or wheels. Thus the capsubot is hermetically sealable and suitable for in-vivo use.

A 2D hybrid robot with two motion modes: capsubot motion mode and legged motion mode is also designed. It combines the best aspects of capsule and legged robots.


Future applications:

Medical Applications:

  • Surgical assistant: Vision assistant in laparoscopy
  • Medical inspection: Capsule endoscopy
  • Biopsy
  • Drug delivery

Industrial Applications:

  • Engineering diagnosis
  • Underground pipe inspection
