Project Overview: Developed for the Columbia University Robotics Studio (MECE E 4611), this project was awarded an A+ for technical innovation and execution. I designed and constructed a bio-inspired robotic mechanism modeled after a crocodile's structure and movement, integrating mechanical design, advanced FEA simulation, and embedded programming to create a robust, manufacturable prototype.
Responsibilities:
Designed the complete robotic mechanism, leveraging Raspberry Pi for control and servo motors for biomimetic actuation.
Programmed all automated motion routines and sequences in Python.
Used SolidWorks for CAD modeling and Ansys (FEA) for finite element analysis to rigorously optimize stress distribution and improve durability.
Refined part geometry through Design for Manufacturing (DFM) and Lean principles, reducing total 3D printing time by 14%.
Managed the end-to-end assembly process, iterating on mechanical tolerances to guarantee consistent part fit and smooth joint actuation.
Achievements:
Successfully created a functional prototype demonstrating the seamless integration of embedded systems (Raspberry Pi/Python) with mechanical hardware.
Validated the effectiveness of DFM methodologies by achieving a measurable 14% reduction in fabrication time.
Optimized the structural design using FEA, resulting in a durable, lightweight mechanism capable of smooth, controlled movement.
Received the highest possible grade (A+) in an intensive, hands-on graduate robotics course.
