Robotic Bartender & 6-DOF Robotic Arm

🏆  1st Place Dassault Systemes Project of the Year 2020

Inspired by the Makr Shakr, I set out to build a low-cost robotic bartender. Because commercial robotic arms of the size and capability desired cost well over $15,000, I designed and fabricated a custom 6 degree-of-freedom aluminum and 3D printed robotic arm from scratch, optimizing for cost, which I was eventually able to bring under just $3,000. The project on Hackaday has over 130 followers and the CAD files for the robotic arm have over 100 downloads on GrabCAD.

Custom Swerve Drive Module

This custom-designed swerve drive module uses two brushless DC motors to control the rotation of a 4-inch traction wheel, as well as the direction in which the wheel points. It integrates encoders and sensing for both rotating axes. When 4 of these modules are placed at the corners of a mobile robot, features such as strafing, turning while driving, and traction control is enabled. Over 300 followers on Hackaday.

TecConnect Proposal & Platform

🏆   1st Place Grand Prize Winner @ AI4ALL CreAItivity Challenge 2020, 🏆1st Place Grand Prize Winner @ Saratoga Congressional Hackathon 

TecConnect allows impoverished and wealthy schools to easily connect and transfer online learning devices such as laptops and tablets. Due to the COVID-19 pandemic, low-income students don't have access to devices, and their schools are not able to provide them. Students are falling behind in their education. Wealthier schools have a surplus of devices in school and a low demand from their own students, meaning these devices are sitting idle. We developed TecConnect to solve this problem and keep the world learning. 

In order to get cinematic shots centered around a human, I designed an autonomous drone that can be controlled using hand gestures. A raspberry pi camera is used to sense the hand gestures and a GoPro is used for recording. The raspberry pi communicates with an Ardupilot flight controller to generate a flight path and triggers the recording of the GoPro. The frame is custom-designed for our electronics and is enclosed for safe operation. Flight time of up to 7 minutes.

As an intern for the University of Washington Aeronautics and Astronautics CubeSat Team, I designed structural components for their latest nano-satellite mission, SOC-i. SOC-i is set to launch in April 2022 to the International Space Station for deployment and will demonstrate an optimal guidance and navigation system. I designed components for the reaction wheel assembly remotely, and then sent them to be manufactured on-site in Seattle. 

For the 2020 FIRST Robotics Challenge we needed to pick up balls off the ground and collect them. To do so we put a gap in our robot's frame, and established the requirement that the intake (pickup system) must be able to center the balls. This design uses mecanum rollers, which are wheels with angled rollers around them, to center the balls. It uses pneumatic-actuated pistons to deploy and retract the intake, and a brushless DC motor to power the two rollers.

2021 FRC Infinite Recharge @ Home Robot

🏆   Skills Competition Finalist in Carbon Group 🏆  Engineering Excellence Award

"Guppy" is team 649's robot for the 2021 Infinite Recharge Replay challenge. The robot can autonomously navigate the field, pickup 7-inch diameter foam balls, hold up to 3 balls in its feeder system, and launch those balls out to distances up to 60 feet. Guppy is uniquely small, and features engineered mechanisms such as the acme-screw actuated variable-hood for the ball shooter. As the hardware lead, I managed the development and design of each subsystem and mechanism, as well as fabrication and assembly.
