Mechanical Engineer, Roboticist, Maker
Welcome to my portfolio — I’m Jonathan Wallen, a mechanical engineer specializing in robotics and product development.
I design robust, scalable hardware systems that power cutting-edge autonomy, from autonomous excavators to underwater robots, to robotic arm. This site showcases a range of professional and personal projects that integrate engineering precision with practical deployment.
Background:
- Ph.D Candidate in Mechanical Engineering @ UHM
Research Topic: Robot localization and modeling of dynamic environment features - M.S. in Mechanical Engineering @ UHM 2021
- B.S. in Mechanical Engineering @ UHM 2019

Diverse Work History
My professional experience is in mechanical design, autonomous system engineering, design for manufacture and product release, state estimation, and control systems. I have worked on a diverse range of robotic systems; from large construction robots to compact autonomous underwater vehicles. I enjoy leading teams and projects.
My research focused on making machines and systems more capable of high fidelity and highly “intelligent” performance. I went about this by building upon and combining the foundations of system design, control theory, dynamical systems, machine learning and state estimation to find automated solutions to complex problems.
