Welcome to Helping Hands

Our team is comprised of students of electrical engineering at Northern Arizona University, we aim to create a cost effective and 3-D printable electronic prosthetic that can be easily assembled and distributed worldwide. With the help of our clients Felicity Escarzaga and Dr. Kyle Winfree, we will do everything in our power to complete the project. Or at least start something great that next year's set of engineers will be able to pick up where we left off.

Meet the Team


Team Lead

Ben is from Sedona, Arizona and always dreamt of changing the world. He is currently studying electrical engineering and physics and Northern Arizona University in an effort to make that dream a reality.



Chathura is an undergraduate transfer student from Sri Lanka to Northern Arizona University. After completing his studies at Northern Arizona University, he plans to return home and work for his father's company.



Breanon Mcnair is an electrical engineering student from Hawaii that has a concentration and passion in robotics and mechatronic technologies. His plan is to one day work more extensively with biomechanics in an advanced sense and develop prosthetics for the disabled.



Hongchen is from Chongqing, China. Having studied at Northern Arizona University and Chongqing University of Posts and Telecommunications. He will graduate and return to China in May 2020.
