Project Focus

This project focuses on the design of micro-pillars with focus on understanding adhesion and tractive properties. Understanding such key mechanics allows for tuning these pillars and micro-patterned surfaces for multiple applications from in vivo surgical robotics, to cell manipulation. Collaborators on this project have included Dr. Kurt Maute (CU-Boulder Aerospace Engineering Sciences) and Dr. Rong Long (CU-Boulder Mechanical Engineering). Project funding and recent peer-reviewed papers are listed below.

Surgical Endoscopy (2012): Surgical Evaluation of a Novel Tethered Robotic Capsule Endoscope using Micro-Patterned Treads

Abstract: The state-of-the-art technology for gastrointestinal (GI) tract exploration is a capsule endoscope (CE). Capsule endoscopes are pill-sized devices that provide visual feedback of the GI tract as they move passively through the patient. These passive devices could benefit from a mobility system enabling maneuverability and controllability. Potential benefits of...

ASME Journal of Medical Devices (2010): Micropatterned Treads for In vivo Robotic Mobility

Abstract: Despite revolutionary advances in many fields of medicine, there are no active mobile in vivo devices commercially available, or in use, today. Several research groups are actively looking at a number of mobility methods in a number of lumens but little commercial work has been done. While robotic surgery...
