About Me
My name is Ümit, and currently I am a PhD student at the University of Massachusetts Amherst. Previously, I was a full-time engineer at ASELSAN , and an undergraduate student & researcher at Kadir Has University .
Research
My research focuses on soft robotics, particularly snake-inspired soft robot design and locomotion. I aim to understand how snakes exploit frictional anisotropy to achieve locomotion, and how this principle can be replicated through soft materials and compliant structures. Previously, I contributed journal papers on haptic interfaces & wearable haptic device design, multi-robot coordination, and visible light positioning.
Soft Robotic Snake Design & Locomotion
Ph.D. Research · University of Massachusetts Amherst (2024 – Present)Advisor: Assist. Prof. Gina Olson
Developing a soft robotic snake to achieve bio-inspired locomotion on heterogeneous surfaces. Fabricated 2+ generations of McKibben actuators to improve pneumatic actuation quality and tested 5+ bio-inspired skin designs through elastomer molding and FDM-based thermoplastic printing. Demonstrated soft robotic snake locomotion on 5 different heterogeneous surfaces and correlated locomotion performance to friction test results — the first study to establish this link. Findings revealed that anisotropic friction alone does not determine locomotion performance, motivating ongoing work on mechanics of surface-snake scale interplay. First-year results published at RoboSoft 2026.

Haptics
Wrist-Worn Haptic Device
Senior Thesis · Kadir Has University (2022 – 2023)Advisor: Assist. Prof. Mine Sarac Stroppa
Designed a wrist-worn haptic interface that relocates tactile feedback from fingertip to wrist for freer VR/AR interaction. Built a custom voice-coil actuator with optimized neodymium magnet and coil geometry, iterated through 10+ 3D-printed case prototypes, and implemented embedded firmware for real-time actuation with tunable intensity. Validated through user studies on stiffness discrimination. Two publications: IEEE World Haptics 2023, IEEE RA-L 2024.

Visible-Light Positioning
Undergraduate Research Assistant · Kadir Has UniversityAdvisors: Emeritus Prof. Erdal Panayirci and Assoc. Prof. Taner Arsan
Contributed to the development of a spatial modulation-based 3D indoor visible light positioning (VLP) algorithm that achieved positioning errors an order of magnitude smaller than conventional RSS-based techniques. Designed and executed MATLAB simulations including user trajectory modeling, SNR-dependent pilot selection, and Monte Carlo-based error analysis across indoor environments.
