Changyi Lin

I am a third-year PhD student at CMU Safe AI Lab, advised by Prof. Ding Zhao. I am fortunate to work closely with Dr. Yuxiang Yang and collaborate with Google DeepMind Robotics team.

I received dual bachelor's degrees in ME and CS from Huazhong University of Science and Technology (HUST). After that, I spent a gap year exploring robotics research at Tsinghua Embodied AI Lab, advised by Prof. Huazhe Xu.

Research

I am passionate about Robotics and AI, with a research focus on whole-body loco-manipulation control, visual-tactile sensing, intelligent hardware design, and reinforcement learning. My goal is to develop robotic systems that can fully perceive, deeply understand, and safely interact with the physical world.

	LocoTouch: Learning Dynamic Quadrupedal Transport with Tactile Sensing Changyi Lin, Yuxin Ray Song, Boda Huo, Mingyang Yu, Yikai Wang, Shiqi Liu, Yuxiang Yang, Wenhao Yu, Tingnan Zhang, Jie Tan, Yiyue Luo, and Ding Zhao CoRL 2025 paper \| website \| video \| code \| X \| media(IEEE Spectrum) Tactile sensing unlocks a new level of contact-rich interaction for legged robots! Equipped with a high-density distributed tactile sensor, our quadrupedal robot can transport everyday objects without mounting or strapping. The transport policy achieves zero-shot sim-to-real transfer, featuring two task-agnostic components: high-fidelity tactile simulation and robust, symmetric, frequency-adaptive gaits.
	LocoMan: Advancing Versatile Quadrupedal Dexterity with Lightweight Loco-Manipulators Changyi Lin, Xingyu Liu, Yuxiang Yang, Yaru Niu, Wenhao Yu, Tingnan Zhang, Jie Tan, Byron Boots, and Ding Zhao IROS 2024 (Featured Cover on IEEE Spectrum) paper \| website \| video \| hardware & code \| mac-mini setup \| X \| media(IEEE Spectrum Cover, TechXplore, CMU Engineering News) Limbs are not just for walking, they can be arms too! We reimagine quadrupedal limbs as 6-DoF arms by equipping them with custom-designed manipulators that mimic huma wrists. Powered by a unified whole-body controller, LocoMan can perform a wide range of dexterous manipulation tasks.
	9DTact: A Compact Vision-Based Tactile Sensor for Accurate 3D Shape Reconstruction and Generalizable 6D Force Estimation Changyi Lin, Han Zhang, Jikai Xu, Lei Wu, and Huazhe Xu RAL & ICRA 2024 (The First VBTS Under $100) paper \| website \| video \| hardware & code \| dataset \| X \| tutorial-en \| tutorial-cn 9DTact = 3D Shape Reconstruction + 6D Force Estimation! Only white light! No markers! One-shot calibration! Easy fabrication! Open source! So many features to explore! Why not check out the website?
	DTact: A Vision-Based Tactile Sensor that Measures High-Resolution 3D Geometry Directly from Darkness Changyi Lin, Ziqi Lin, Shaoxiong Wang, and Huazhe Xu ICRA 2023 paper \| website \| video \| hardware & code \| X \| media(Technology) The deeper you press, the darker you see! We leverage the reflection property of translucent silicone to reconstruct 3D contact geometry using only white light. We also demonstrate its robustness and feasibility for non-planar contact surfaces.
