June - September 2017
two degree-of-freedom index finger exoskeleton
My task was to design and build an exoskeleton that moves a passive index finger to measure its stiffness (distance & force). I created the mechanical structure that would align to natural finger motion, and my teammate, Uksang Yoo, programmed the mechatronic and data collection portions of the mechanism.
Working with Dr. Youngjin Na, I developed an understanding of the biomechanical properties of the index finger and constraints for passive finger movement and rotation. I created an initial design of mechanical exoskeleton and built a paper model as a proof-of-concept. I then modeled the mechanism in SolidWorks to simulate the actuation and range of motion of the device before machining, assembling, and testing the final device.
