Yuxiang Ma

PhD Candidate, MIT Mechanical Engineering

I am a PhD candidate in Mechanical Engineering at MIT, advised by Professor Edward Adelson. My research focuses on the intersection of visuo-tactile perception and embodied AI, spanning the full robotics pipeline — from tactile sensor design and hardware engineering to foundation model learning and policy deployment for complex real-world manipulation.

I am particularly interested in overcoming the robotic "data bottleneck" by building scalable, interactive data-collection frameworks with richer sensing modalities. In Summer 2025, I interned at the Robotics and AI Institute, where I worked with Team Capture to design a handheld UMI-style device integrating force-torque and tactile sensors for portable, multimodal manipulation data collection.

I received my B.Eng. from the Tsien Excellence in Engineering Program (TEEP) at Tsinghua University in 2020. I also spent time as an undergraduate researcher in the Xu Group at UC San Diego, working on wearable ultrasound imaging and elastography.

In my spare time, I enjoy weightlifting and playing basketball.

Research

T3

Transferable Tactile Transformers for Representation Learning Across Diverse Sensors and Tasks

Alan Zhao, Yuxiang Ma, Edward Adelson

CoRL 2024

A tactile representation learned from multi-sensors and multi-tasks, and a tactile dataset containing over 3M tactile images collected from 13 sensors and 11 tasks.

GelLink

TacLink: A Compact Multi-phalanx Finger with Vision-based Tactile Sensing and Proprioception

Yuxiang Ma, Jialiang (Alan) Zhao, Edward Adelson

ICRA 2024

GelLink has three phalanges and two DOFs, actuated by only one motor and visualized by only one camera. A compact mechanism with a mirror-based tactile sensing system achieves a versatile multi-phalanx design with embedded tactile sensing and accurate proprioception.

Scalable Fin Ray

Scalable, Simulation-Guided Compliant Tactile Finger Design

Yuxiang Ma*, Arpit Agarwal*, Sandra Liu*, Wenzhen Yuan, Edward Adelson

RoboSoft 2024

A simulation framework combining FEM mechanical simulation and physically based rendering (PBR) for end-to-end forward design of GelSight Fin Ray sensors, enabling faster design and prototyping of new sensors.

Baby Fin Ray

GelSight Baby Fin Ray: A Compact, Compliant, Flexible Finger with High-Resolution Tactile Sensing

Sandra Liu, Yuxiang Ma, Edward Adelson

RoboSoft 2023

Flexible mirrors and high-elongation silicone fluorescent paints incorporated into the GelSight Baby Fin Ray enable grasping through clutter and classification of in-shell nuts.
