CoStream: Compositional Multi-Stream Framework for Multi-Modal Manipulation

Haonan Chen*, Yuxiang Ma*, Stephen Tian, Xiaoshen Han, Wenlong Huang, Yunzhu Li, Jiajun Wu, Edward Adelson, Yilun Du

Coming soon, under submission to RSS 2026

A composable foundation model combining a VLM planner, world model, and high-frequency reactive policy based on tactile and force-torque sensing. The multi-stream structure solves high-level planning and fine-grained manipulation skills at different levels, enabling long-horizon tasks with reactive correction behavior.

InvariantCloud: Globally Invariant Point Cloud Registration for High-Precision 6DoF Tactile Pose Tracking

Pengfei Ye, Yuxiang Ma, Yi Zhou, Molong Duan

ICRA 2026

A framework for 6-DoF tactile object pose estimation using vision-based tactile sensors, leveraging globally invariant surface marker arrangements for one-shot point cloud registration — achieving sub-2° yaw tracking error and addressing cumulative drift in z-axis rotation estimation.

Dynamic Regrasping

Dynamic Regrasping with Asynchronous Vision Feedback using a Minimalist Robotic System

Yuxiang Ma, Edward Adelson

ICRA RoboLetics 2.0 Workshop 2025

A minimalist dynamic regrasping approach that throws an object into a ballistic trajectory and regrasps using computed-torque control, refined with asynchronous visual feedback — demonstrating successful mid-air regrasping without high-speed vision or complex hardware.
