Ruixiang Cao

IEEE/RSJ IROS 2025 · First Author

Trains a monocular navigation model via self-supervision from uncalibrated, human-captured videos, yielding a generalist policy that guides various robots in unfamiliar environments.

ACM SIGGRAPH 2025 · Best Paper Award · Co-first Author

Transforms radiance-based volumetric representations (e.g. NeRF) into physically fabricable Volumetric Printing Primitives for high-fidelity full-color 3D printing. Recipient of a SIGGRAPH 2025 Best Paper Award.

Kyoto University, Learning Machines · First Author

A Printable-Voxel framework that removes view-dependency and maps digital RGB into a physical CMYKWCl color space, directly outputting full-color voxel grids for photopolymer-jetting 3D printing.

IEEE IROS 2022 · First Author

Published at IROS, a top-tier robotics conference. Proposes an omnidirectional wheel-leg dual-mode transformable mechanism.

Club Project · Real-time Video Light Wall · Jetson + Arduino

A wall of filament LEDs driven by Jetson Xavier NX and Arduino, rendering a live camera feed as a warm-toned light display.

Club Project · Stepper Motors Playing MIDI · Arduino

Parses MIDI with Python’s mido and drives stepper motors over serial so the motors “sing” by pitch and rhythm.

Course Project · Post-apocalyptic Survival Shooter · Unity

A self-made post-apocalyptic survival shooter with a building system, environment interaction, inventory, and original sound effects.

Lab Project · ShanghaiTech MARS Lab

Led, as the core student lead, the build of a spherical dome light-field 3D capture rig for facial geometry and material capture.
