Selected works

A team-based VR rhythm game that imagines a future industrial workplace. The player operates a factory robot remotely and cuts steel pipes in time with music, turning repetitive industrial work into a rhythm-based interaction.

My role

Core mechanics and VR implementation: grabbing and cutting physics, Meta Quest and VR setup, and repository integration.

Format

Four-person undergraduate team project

A small companion robot designed to bring a playful moment to desk work. When its infrared sensor detects a nearby hand, two motors raise the robot’s face while the LED eyes change from a sleeping expression to a smile. After five seconds, it returns automatically to its idle state.

Implementation

Embedded programming, circuit assembly, sensor processing, dual-motor motion and LED expression control.

Hardware

OpenRB-150 · two XL-330 motors · DMS-80 infrared sensor · four 7-segment LEDs

Logic

Two-state interaction with sensor thresholding, timed actuation and automatic reset.

Players register reference images—such as a chair, bottle, mouse, laptop or person—and the system connects these targets to objects in the surrounding scene. The player then searches the real space through the headset and shoots the requested target to earn points.

Game system

Timed rounds, hit scoring and persistent high-score display.

Feedback

Controller vibration when firing and custom sound effects to confirm successful hits.

I configured and operated a mobile manipulator in a Linux-based ROS environment, using SLAM and RViz to observe the mapped arena, laser-scan data, costmaps and robot pose while coordinating base navigation with arm movement. I also followed guided Gazebo exercises to learn the basic robot-simulation workflow.

Task

Navigate within a bounded arena and control the articulated arm to interact with a cylindrical target.

I designed and implemented a conversational care prototype that uses LINE as a familiar interface for older adults. Gemini classifies intent and generates context-aware responses, while persistent memory helps conversations continue naturally across days.

Core features

Scheduled check-ins and medication reminders, persistent conversation memory, dynamic Flex Message cards, and family photos formatted as digital postcards.

Accessibility

Large text, high contrast and one-tap interactions designed to reduce the learning burden for older users.
