- Head design, prototype, and analysis of a six-wheel, rocker-bogie suspension rover capable of driving over obstacles a foot tall, on sandy terrain, and up 30 degree gradients using terramechanics and force analysis- Downselect rover suspension designs by testing dynamic models with a physics engine on NX Motion, evaluating numerical results of wheel dynamics and rover stability- Lead manufacturing of a prototype rover with rocker bogie suspension made of commercial components, making it operational within two weeks of conception

College Park, Maryland, United States

- Organize system-wide documentation and guide design decisions for subteam members, culminating in technical deliverables for competition advisors on the feasibility of our design- Formulate testing plans and literature studies to redesign a sub-assembly by exploring new options for faster, improved excavation rates in a new soil type- Conceptualize and prototype foam diffusers to treat the soil being excavated to increase workability- Oversee design of mechanical structures and mechanisms for manipulating and removing soil

University Of Maryland, College Park

- Analyzed fastener and weld bending stresses in addition to cantilever deflection cases to ensure auger assembly structural integrity, with assembly remaining intact in testing, in transit and at the competition - Performed FEA analysis on ANSYS to optimize the durability of excavation tools against the soil front pressure by altering their material and shape while also keeping manufacturability in mind- Utilized NX NASTRAN and hand calculations to account for the deflection and stresses on the cutterhead, which included its tools and its transmission, to justify their resilience against soil front pressure and pipe jacking forces in the range of several thousands of pounds- Procured engineering drawings to list specific fits, dimensions, and tolerances in the ASME Y14.5 standard for the auger assembly, resulting in little physical interference and being one of the first systems to be tested and deemed operational

Silver Spring, Maryland, United States

University Of Maryland, College Park

- Ideate and build a custom testing fixture for pneumatic artificial muscles to characterize the torsional stiffness, achieving 2% error and 150 pound-inches of torque with resolution of 0.02 degrees- Calibrate load sensors and encoders to sample PAM strength data using custom software and hardware with a combination of Arduino and MATLAB in experiments- Collaborate with chemical engineers to perform four-point bending tests on cryogenic resin samples to compare and present relative flexural stiffnesses, choosing optimal samples for further testing

Cape Canaveral, Florida, United States

- Improve the time and complexity of a frangible joint assembly installation process by blocking the flow of liquid adhesive paste into sensitive spaces through the use of custom 3D-printed component- Create and use a reusable fixture to test and find an optimal resin injection technique and port spacing to join a large-scale composite flange assembly- Receive skills certification and training for hand-drilling precision holes, installing buck rivets and HI-LOK fasteners based on engineering drawings and technical specifications- Implement visual and verbal work instruction of dry fiber layup and infusion of a 16-foot diameter composite tool, facilitating communication and critiques between off-site engineers and technicians

Rockville, Maryland, United States

- Formulated a script in Cameo System Modeler to automatically update document representations and references in a documentation mapping containing over 800 fleet maintenance procedures- Programmed a set of macros on Cameo System Modeler to generate activity diagrams of paper-based maintenance procedures with steps in chronological order, reducing the time to make diagrams by over 75%
