MT_EAI

MT_EAI is a robotic tactile manipulation dataset from Meituan, collected using the single-arm Pika platform and the dual-arm Tianji M3 and M6 platforms. It covers manipulation tasks including pick-and-place, sorting, stacking, insertion, and wiping.

MT_EAI is distributed across two repositories. This repository and rshcareer18/MT_EAI jointly host the published data batches. Please consult both repositories to access the complete published collection.

Dataset Overview

The following statistics represent the combined, deduplicated collection across both repositories as of October 26, 2026:

• Pika: 35 tasks, 4,628 demonstration trajectories, and 2,983,071 frames, temporally aligned at 25 Hz. The data include global and wrist RGB images at their original resolution, auxiliary fisheye RGB images where available, joint and gripper position measurements, and six-dimensional force/torque measurements from two TactaS48 tactile pads.
• Tianji M3/M6: 14 tasks, 2,460 demonstration trajectories, and 1,800,893 frames, temporally aligned at 20 Hz. The data include main and bilateral wrist RGB images at their original resolution, joint and gripper state measurements, and matrix-form tactile measurements from four DMTacW2M tactile pads.

Data Organization

Data are organized by robot platform under MT_EAI_Pika/ and MT_EAI_Tianji/ and distributed as .zarr.zip archives.
