I completed my third co-op at the Robotics and AI Institute in spring/summer 2025. I was at the institute for 6 months full time (Jan-Jul) and 2.5 months part time until mid September.
While at the institute, I was part of a 5 person research project called Underactuated Robot Manipulator (URM) led by Professor Aaron Dollar from Yale. This project sought to explore how underactuation can enable passive adaptation to uncertain environmental constraints during manipulation. Conventional robot arms can exert very high forces on their environment when in contact with unforeseen obstacles, potentially resulting in damage or injury. Underactuated systems, however, can exhibit passive reconfigurability in response to contact which may enable them to achieve manipulation objectives in contact-rich environments without excessive forces on the environment.
During my time at the institute, I got the opportunity to work on the following:
I collaboratively developed and implemented a second-generation underactuated delta manipulator with rolling diaphragm actuators and a fluidic differential
Led joint-module design, creating compact DMLS-printed components with integrated fluid passages and post-machined precision interfaces.
Designed or updated 20+ unique mechanical components; coordinated fabrication with external vendors and performed full system assembly.
Developed and implemented a spring-based gravity-compensation mechanism within the manipulator’s confined geometry.
Prepared figures, renderings, and manuscript materials for a forthcoming publication and supported experimental characterization of robotic performance.
