First

Custom 1 kW BLDC Actuator

• Designed a four-layer STM32 inverter for three-phase BLDC motor control.
• Integrated encoder feedback, current sensing, CAN, and regenerative overvoltage protection.
• Built a modular 19:1 cycloidal gearbox and iterated through multiple PCB revisions.

Three-Stage Buck Converter

• Designed a three-stage board providing 12 V, 5 V, and 3.3 V power rails.
• Validated the 10 W supply under load and measured output ripple with an oscilloscope.
• Used the prototype to de-risk power delivery for a larger custom motor controller.

Automated Dog Treat Launcher

• Built an automated treat dispenser with a lead-screw elevator and differential turret.
• Integrated servos, sensors, custom PCB wiring, and jam detection.
• Programmed an autonomous daily dispensing cycle with fault handling.

Honda Cobot Assembly Demo

• Helped create a UR10e cobot demo that assembled a 3D-printed Honda CR-V model.
• Designed a magnetic rack-and-pinion end effector with Arduino-controlled tooling.
• Achieved a 100% assembly success rate throughout the public demo day.

Autonomous Pet Feeder

• Built an Arduino-controlled feeder with a stepper-driven auger and servo-driven bowl carriage.
• Integrated ultrasonic, infrared, camera, and limit-switch sensing with a responsive state machine and web UI.
• Calibrated repeatable three-second servings and offloaded camera-based pet identification to a Flask server.

Robot Handwriting and Trajectory-Control System

• Improved a Kinova robot system for repeatable handwriting and rehabilitation trials.
• Diagnosed motion jitter and replaced the inverse-kinematics approach.
• Processed writing trajectories and redesigned the marker end effector.

VEX Robotics Hardware Leadership

• Directed mechanical development for two complex VEX U Worlds robots.
• Delivered custom climbing, scoring, drivetrain, sensor, and CNC-machined subsystems.
• Won 12 awards, the Worlds Build Award, and the AI Skills World Championship.

VEX Robotics Qualification Robots

• Directed mechanical design for four VEX U competition robots.
• Used adjustable, test-driven mechanisms to improve scoring consistency.
• Reached third globally, earned eight awards, and set an unofficial autonomous-skills record.

VR Hand Tracking Characterization

• Built repeatable VR hand-tracking experiments around a 7-DOF KUKA cobot.
• Combined motion capture with a 3D-printed hand to establish sub-millimeter ground truth.
• Compared Meta Quest headsets in research published at IEEE VR 2025.

Robot-Served Snow Cone Cell

• Helped build a robot cell that prepared and served snow cones automatically.
• Designed the cell layout and a physical ordering interface for red or blue cones.
• Connected user input to a ROS 2 sequence that served roughly 50 conference guests.

VEX U Intake and Launching Mechanisms

• Developed intake and launching mechanisms for two VEX U competition robots.
• Improved the six-wheel intake to greater than 95% success through friction and tension tuning.
• Collaborated with a design team of more than 10 students and qualified for the World Championship.
