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. I lead a physical AI team spanning two CMU research groups, the labs of Prof. Xu Zhang and Prof. Min Xu. My Ph.D. work built atomically thin synaptic devices for neuromorphic computing; now I'm teaching robots to feel.

Recent updates

  1. Oct 2026

    LeRobot tactile camera plugin released. lerobot-camera-paxini exposes Paxini PX-6AX GEN3 tactile sensors as LeRobot cameras, covering every variant from 9 to 239 taxels. Install it from PyPI or read the source on GitHub.

  2. Sep 2026

    Four-camera tactile rig calibrated. The rebuilt SO-101 bench records a wrist camera and an egocentric view that match pi0.5 pretraining, plus two side cameras facing each other across the table for 3D reconstruction. All fixed cameras are calibrated to one shared table frame.

  3. Sep 2026

    Tactile policy checkpoints released. Four ACT variants trained on SoTac with different tactile encoders (MLP, predictive, echo state network, and the last two combined), plus pi0.5 full and LoRA fine-tuned baselines, openly available on Hugging Face.

  4. Sep 2026

    Tactile dataset visualizer online. A LeRobot dataset viewer extended for touch shows per-taxel force arrows, a contact timeline and the raw high-rate tactile stream next to the camera views. Try it on Hugging Face Spaces.

  5. Sep 2026

    SoTac grows to 163 curated episodes. A 100-episode contributed batch is merged into the tactile corpus, which now spans 55,457 frames across four tasks with reproducible curation from the append-only raw set, openly available on Hugging Face.

  6. Aug 2026

    XLeRobot fully assembled. The dual-arm mobile manipulator is standing: two SO-101 arms with fin-ray grippers, a camera mast and a mecanum wheel base on a lab cart. Wheel-mount and onboard-compute upgrades are next.

  7. Aug 2026

    Reservoir computing manuscript in preparation. First-author paper on mechanism-anchored modelling of MoS2 synaptic devices for physical reservoir computing — bridging my device work and learning systems.

  8. Jul 2026

    AmazingHand built and tested. The 3D-printed dexterous hand is assembled and running gesture demos through a bus servo adapter, joining the lab's dexterous-manipulation platform.

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.

Dataset ↗
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.

Code ↗
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.

New direction

Power-efficient tactile sensing

Mobile manipulators on battery power can't afford power-hungry tactile arrays — a constraint I hit first-hand on XLeRobot. Building on my low-power device background, I'm exploring high-frequency tactile sensing that embedded robots can actually carry.

Earlier research — from atoms to synapses

Ph.D. · devices

2D synaptic transistors

My dissertation built atomically thin MoS2 synaptic transistors that store analog weights through Maxwell‑Wagner interfacial charging in binary oxides — reaching a ~105 analog switching ratio at about 50 pW programming power, orders of magnitude below biological synapses. A physics-based compact model captures the charging dynamics and transport. (First-author paper in 2D Materials, 2024.)

Ph.D. · computing

Physical reservoir computing

One synaptic transistor's intrinsic dynamics can compute: used as a time-multiplexed physical reservoir with only a linear readout, it reaches ~93% on MNIST — and transfers to temporal signals, improving ECG arrhythmia detection by 13 points and industrial fault detection by 17.5 points over no-reservoir baselines. First-author manuscript under review.

2D materials

Growth, devices & collaborations

Before devices came the atoms: MBE growth of monolayer TMD alloys with RHEED, STM and ARPES characterization at Nanjing University, then a full cleanroom pipeline at CMU — deposition, lithography, etch, measurement. Along the way I contributed to collaborative work on reconfigurable thermal metamaterial pixel arrays (Nature Communications, Nano Letters) and high-mobility tellurium photodetectors.

In the lab

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.
