A mobile online action game merging real and virtual space via Earth data and player location.

• Mobile device's native map and Unity are seamlessly integrated with real-time battles
• On-demand voxel map reflecting each player's real landscape
• PVP, PVE & Solo — up to 4 players per PVP, different map each battle
• Custom geospatial DB from public open geodata
• Game server built with the uLink network framework

A personal project bringing a trained locomotion policy into Unity via ONNX, with ongoing improvements through study and iteration.

• Supports forward walking, backward walking, lateral movement, and turning in place
• Trained with 512 parallel environments through iteration 950, then resumed with 1,024 environments through cumulative iteration 1,500 before ONNX export
• 61 actor observations drive 14 joint-position actions, with physics at 200 Hz and policy updates at 50 Hz
• Uses the BAM M6 actuator model for Dynamixel XL330 servos

• Generates videos & images from the driver's POV while varying weather, time of day, road signs, and traffic
• Built with Unity's climate and screen-recording assets

• Developed features: IAP product syncing from servers, player-to-player messaging, and a new game-over screen

A browser game exploring Mars with the Curiosity rover, built from an actual Mars height map and satellite imagery.

• Developed click-to-move navigation, an image cache system, and a custom rim-lighting shader

Prototype short-range radar for automobiles.

• Developed the A/D converter controller and radar signal-processing software
• Multithreaded architecture with DAQ control and a 50ms view-update timer

A micro mouse with a webcam: capture images, detect maze walls, and drive to the goal.

• Built hardware with DSP (TMS320C32) & EPLD, CMOS sensor (OV7620), step-motor control
• Image-processing & maze-solving algorithms in C
