I'm Ben.

I'm a junior at UPenn who's fascinated by technology and engineering. I'm also interested in science, sports, history, and music. When I'm not CAD-ing or coding, I like to hang out with friends, play the guitar, and longboard. I hope to work in robotics and mechanical design and eventually change the world.






Aluminum Longboard

Longboard Design and Analysis

This is a 38" aluminum longboard deck I designed while taking courses in Statics and Manufacturing. I wanted to apply the knowledge I was learning in these classes to create a longboard that was strong and light. The "beams" of the board are thicker in the middle than on the edges, so bending stress is evenly distributed throughout the body. Simulations suggest the board can theoretically hold 1000 lbs.

Quadrupedal Robot

Four-Legged Research Robot

This is a robot I am building for Kodlab. I took an existing leg design and made a body that allowed for full range of motion while minimizing weight. In the future, I hope to test leaping capabilities, gait kinematics, and possibly alternate leg designs that are more flexible.

Nerf Dissection

Dissection and Modeling of a Nerf Blaster

As part of the "Dissect" assignment in Introduction to Mechanical Design (MEAM 101), my group fully dissasembled a Nerf Maverick blaster, modeled each part in Solidworks, and created a full assembly followed by an explosion-collapse video. View on GrabCad

Rapid-Prototyped Guitar

Rapid-Prototyped Guitar

Inspired by my internship at Fender, I decided to make my own guitar from scratch. I used lasercut MDF and acrylic for the body, 3D-printed neck pieces, and a rectangular aluminum tube for support. Coupled with some purchased parts and components from my old Epiphone, the guitar is fully functional and sounds great. View in OnShape

Eagles Stirling Engine
Engine Animation

Eagles-Themed Heat Engine

For MEAM 201 Machine Design and Manufacturing, I made most of the parts in a previously designed Stirling engine. In order to add my personal touch to the project, I made the engine Eagles themed. During testing, the engine achieved a speed of 850 RPM. View on GrabCad

Aluminum Menorah

CNC'ed Aluminum Menorah

For Hannukah this year, I designed and made a custom menorah with aluminium and steel nuts. Using the CNC machines at UPenn's machine shop, I created a special fixture that allowed me to cut an oversized piece. Screws held the stock in place and were removed as necessary to allow the cutting head through. View on OnShape


Hockey Playing Robots

For the final project in Design of Mechatronic Systems, my group created a team of autonomous hockey playing robots. These bots could search for the puck using IR light, navigate a rink using a constellation of stars above, and plan its driving path to the goal. View on Github

da Vinci's Tank

Leonardo da Vinci's Tank

In MEAM 101's "Machine" project, I created a small scale tank based on the drawings of Leonardo da Vinci. This build combined a centuries-old design with modern prototyping techniques, including 3D printing, to create a mobile working model (except for the cannons). View on GrabCad

Vertical Wind Turbine

Vertical Axis Wind Turbine

As part of our junior design lab, my group designed, analyzed, and built a wind turbine. After creating a model and characterizing it in a wind tunnel, we scaled up our design and allowed the blades to telescope in and out. This kept the turbine compact during transport while maximizing power output. We generated 10.35 watts in our final test, finishing second in the class.


Motorized Two-Wheel Scooter

This is a model of the Phunkee Duck scooter board. The Phunkee Duck and its competitors are almost all identical and have an interesting shape. I also worked with PhotoView 360 in Solidworks to create more photo-realistic renderings. View on GrabCad

Pressfit Buckyball

Lasercut Geodesic Sphere

This is a truncated icosahedron made from 20 hexagons and 12 pentagons. I lasercut all of the pieces and, after many tries, assembled the structure without any adhesives. There are more than 90 edges that are pressed together, and each edge has the same peg and slot design. View on GrabCad

UPenn Art Models

Small-scale Statue Models

As a design challenge, I decided to model two of UPenn's most well known pieces of art: The Button and Covenant. After scaling them down, I added some features to make the models printable. View on GrabCad
