Robotic Arm

(Jan 2020 - Aug 2021)

I have designed, tested, and released my own custom 6 DoF robotic arm. I learned the basics of kinematics and joint structure when designing the model, and motion planning necessary to control it.

Table Tennis Robotic Arm

(Sep 2021 - Present)

After I tried to intercept ping pong balls with my old robotic arm and found my joint speeds were insufficient, I sought to make a faster and lighter robotic arm. I combined what I learned from my old robotic arm and what I learned at Columbia University to attempt to optimize a robotic arm with the lowest possible joint torques.

Dell

(Aug 2018 - Dec 2018)

For my senior design project at UT, I was tasked to build a dummy server rack with a controllable center of gravity for DELL, so they can run vibration and drop tests on a server frame without destroying actual servers.
