Real-robot garment folding with the bimanual arms.

TL;DR A tabletop vision-language-action model trained on 147M vision-language samples and 15,060 hours of robot data from 12 embodiments, then post-trained on a real bimanual robot with human corrections. It scores 93.6% on RoboTwin 2.0, and its rewind-and-correct data collection reaches 70% success on real Ethernet insertion.

What they do

MR0 is a vision-language-action (VLA) policy plus an agent layer for stationary tabletop manipulation. The policy is trained in three stages on 147M vision-language samples and 15,060 hours of curated trajectories from 12 embodiments, then adapted on a bimanual AgileX PiPER with human corrections. Because the policy only reacts to the current observation, a separate event-driven agent keeps track of what happened across subtasks.

How it works

  • One action space. Trajectories are trimmed and filtered for kinematic and video defects. Their actions are converted to end-effector position, 6D rotation and gripper per arm in a shoulder-centered frame, so single-arm and bimanual robots share one 20-dimensional action.
  • Three-stage training. A Qwen3.5-4B backbone is first pre-trained on FAST action tokens alongside VQA data. An MMDiT flow-matching head then takes over for continuous control, and the policy is finally fine-tuned on real demonstrations and corrections.
  • Rollback and CFG-DAgger. Near a failure the operator rewinds the robot to an earlier state and demonstrates a fix. The replaced policy segment becomes a negative label and the human fix a positive one. At inference, classifier-free guidance steers away from the negative, so no value function is needed.
  • Agent. A Monitor (Qwen3.5-35B-A3B, 2 Hz) captions short windows, a Memory Manager stores them as events, and a Planner runs only when an event changes progress or feasibility.

Results

  • RoboTwin 2.0 (50 bimanual simulation tasks): 93.6% average success (93.2% clean, 93.9% randomized), 8.0 points above ABot-M0.
  • RoboDojo: fifth by success rate in the VLA track (14.63%) with about 13.6k hours of robot data. Open-vocabulary instructions reach only 3.38%.
  • Real robot (letter blocks, garment folding, Ethernet insertion; 30 trials each): neither MR0 nor π0.5 folds a garment after SFT alone. After HG-DAgger, MR0 ties π0.5 on letter-block success and gains most on Ethernet insertion.
  • Ethernet insertion with the same Rollback data: CFG-DAgger reaches 70% success and 0.90 progress, against 60% and 0.67 for RECAP.

Limitations

The agent is shown in two qualitative deployments, not measured. Real-robot tests use one bimanual platform and three tasks. Unfamiliar instructions are weak; for example, on RoboDojo’s Align_blocks task the policy sometimes grasps the box instead of aligning it.

Abstract

We present Meituan-Robotics-0 (MR0), a vision-language-action foundation model and embodied-agent system for stationary-base desktop manipulation. MR0 combines 147 million vision-language samples with 15,060 hours of curated robot trajectories spanning 12 embodiments. A three-stage training recipe aligns multimodal representations with robot behavior through discrete action-token pre-training, transfers these priors to continuous cross-embodiment control through flow-matching mid-training, and adapts the policy through real-world post-training. We introduce Rollback, which pairs replaced policy segments with human corrections to provide positive and negative supervision for CFG-DAgger without value learning or advantage labeling. A unified end-effector interface supports heterogeneous embodiments, while asynchronous action-chunk merging maintains smooth execution under variable inference latency. An event-driven agent maintains persistent task events and reassesses plans when progress or feasibility changes, enabling cross-task retrieval and conditional task resumption. MR0 achieves 93.6% success on RoboTwin 2.0 and ranks fifth in the RoboDojo VLA track. Under matched HG-DAgger post-training, MR0 achieves higher average success rate and progress score than $π_{0.5}$ across three real-robot tasks. On Ethernet insertion, CFG-DAgger trained with Rollback data reaches 70% success and a progress score of 0.90. Qualitative agent deployments demonstrate cross-task event retrieval and recovery from temporarily unsatisfied task conditions.
