Paint the Canvas: 3D Gaussian Splatting for Scene Reconstruction Robot

”Paint the Canvas,” or PTC, is a reconstruction platform enabling the ability to easily re- construct and interact with 3D scenes at an exceptionally low cost. The primary objective of this platform is to allow users to leverage the use of techniques in novel-view synthesis, such as Neural Radiance Fields (NeRFs), 3D Gaussian Splatting (3DGS), or Sparse Voxel Rasterizers (SVRaster), to generate interactive scenes for capturing memories, performing reconnaissance missions, or aid- ing in rescue operations. Our low-cost solution leverages a custom hardware and software stack that is deployable and adaptable to any autonomous or manual capture rig, such as autonomous vehicles (AVs), humanoids, quadrupeds, and/or quadrotors for customizable autonomous data capture.

Rubik's Cube Solving Robot

I made a robot that can solve Rubik's cubes autonomously and quite fast! It was designed to be easily used with normal Rubik's cubes, so that you can take the cube in and out of the robot quickly. More details in the linked GitHub page

Pitt Robotics and Automation Society (RAS)

I’m the project leader for the Pitt RAS Robot Arms Project. I lead a team of 5-7 students in developing diverse robotic arm applications. I manage task distribution, mentor team members, and contribute directly to each project. One of our successful projects last semester was establishing control of an arm using computer vision and ML tracking a human’s arm joints. We presented this project at the city of Pittsburgh’s annual robotics convention.

BopIt Sword

For ECE Junior Design, we were tasked with making any object play like a BopIt. My team chose to make a lifesize replica of the flame sword from The Legend of Zelda: Breath of the Wild. It calls out actions like "swing right", or "stab" and detects if you make them accurately. The acrylic panels hide an LED strips, which makes the sword glow beautifully.

Piano Gloves

This project was part of the class Art Of Making. I made these gloves which have wearable electronics embedded in them to let you play piano on any surface! This was a group project but I did all the hardware and software myself, since the other members were working on another project for our group at the same time.

Automated Recycling Machine

This project was part of the class Art Of Making. This was our capstone project, it is an automated system to rinse and recycle dirty coffee cups, designed to be conveniently used at your local coffee shop. I was the electrical and software and lead.

IoT Dog Feeder

This project was part of the class Art Of Making. We made an IoT device which lets you control a dog food dispenser from an app on your phone, anywhere in the world! It uses littleBits, which is a cool electronic prototyping system for people who have no electronics experience.

Human Game Controller

This project was part of the class Art Of Making. We used the Makey Makey system, which lets you turn any object into a button, and made a fun a videogame controller out of it!

Grisaille and Abstract Self Portraits

I made two self portraits from the same source image, one using the Grisaille style, and one using abstract/expressive coloring. Water-mixable oil paints on canvas. Grisaille is a really fun and interesting style where you only use a single tube (in this case brown) of paint, and thin it with oil and water to create lighter shades.

I made a website that let's you automatically generate many variations of colors to choose from for posterized style images, and then I also painted one myself of my friend from high school and gave it as a gift to him. The image is the painting(s), but the website is linked.
