Robots that feel what they touch.

I'm Jingyi Zou (she/her), a researcher at Carnegie Mellon University's School of Computer Science working on tactile sensing and robot learning — building fingertip sensors, contact-rich manipulation datasets, and policies that use touch, from real hardware to simulation. My Ph.D. work built atomically thin synaptic devices for neuromorphic computing; now I'm teaching robots to feel.

Recent updates

  1. Jul 2026

    Sim-to-real pipeline running end to end. GR00T N1.6 fine-tuned on Isaac Sim demos reaches 50% success in simulation from a cloud GPU; real-robot rollouts via a Raspberry Pi client expose the sim-to-real gap we're now closing.

  2. Jul 2026

    XLeRobot build underway. The dual-arm mobile manipulator's wheel base is printed and assembled; arms, camera mast and fin-ray grippers are coming off the printer next.

  3. Jul 2026

    Dual-Paxini recording unblocked. Extension cables validated — both 52-taxel fingertips now record in real time through the LeRobot stack.

  4. Jun 2026

    MLXTAC released. A 70-episode contact-rich manipulation dataset pairing magnetic tactile sensing with RGB and proprioception, openly available on Hugging Face.

  5. Jun 2026

    Tactile ACT ladder: first phases trained. Baseline and tactile-as-state ACT policies trained across three grasp tasks, with six checkpoints published on Hugging Face.

  6. May 2026

    Gripper jaws v2. Both tactile jaws rebuilt from verified hardware geometry, cutting added fingertip bulk from ~28 mm to ~5 mm.

Along the way

From atoms to robots

Spintronics at UCLA's Device Research Lab (CSST program, Prof. Kang L. Wang), X-ray optics at the Institute of High Energy Physics, and two semesters as TA for CMU's Memory Devices and Micro/Nano Systems Fabrication courses. Cleanroom-trained hands turn out to be good at building grippers.

Research

Hardware

Tactile fingertip grippers

SO-101 gripper jaws redesigned around commercial Hall-effect tactile sensors: a magnet-embedded TPU fingertip for the MLX90393 single-taxel sensor and dual 52-taxel Paxini fingertips, with real-time recording integrated into the LeRobot stack.

Dataset

MLXTAC

A contact-rich manipulation dataset pairing single-taxel magnetic tactile sensing with wrist and top RGB and proprioception — 70 episodes of grasping and pick-and-place, openly released.

Robot learning

Tactile policy learning

Measuring how touch improves manipulation policies by climbing a ladder of tactile integrations in ACT and Pi0.5 — from baseline to tactile-as-state to learned encoders — in a policy-agnostic fork of LeRobot.

Sim-to-real

Sim-to-real with NVIDIA Isaac

An end-to-end imitation-learning pipeline: Isaac Sim tasks and demos, GR00T fine-tuning on a cloud GPU, and deployment to a real SO-101 through a Raspberry Pi robot client — now working on closing the sim-to-real gap.

Platform

XLeRobot — dual-arm mobile manipulator

A low-cost dual-arm, mobile SO-101 platform with fin-ray grippers and VR teleoperation, built for bimanual, contact-rich data collection with tactile integration.

Sensing

Custom 16-taxel tactile PCB

A custom fingertip PCB with sixteen taxels and a microphone channel sampling at ~130 Hz, designed for dense contact-event detection on low-cost grippers.

Ph.D. work

2D synaptic devices & reservoir computing

An interfacial-charge-based MoS2 synaptic transistor with ~105 analog switching ratio at ~50 pW programming power, plus a physics-based device simulator used as a physical reservoir — 92% on MNIST with a single device's dynamics.

Zouki — my research workbench

I built (well, vibe-coded) an AI-assisted workbench that tracks my projects and writes my progress reports. The updates above come from it. Want to help with something? Check the open quests.
