LiberAI introduces Liber-0 robot manipulation model, reporting 36% success on new tasksMachine translation

AI introduction

LiberAI says Liber-0 was pretrained on more than 2.2 million hours of human experience without robot demonstrations collected specifically for the tested tasks. In its reported evaluation of 600 trials across 60 tasks, overall success was 36%, falling to 10.5% on challenging multi-step tasks.

这看起来真是一次极其出色的机器人训练技术发布。 工人做日常工作时戴上一只重 131 克的轻薄传感手套,记录精确的手部动作,因此收集数据无需机器人。 中国机器人初创公司 LiberAI(@liberai_robot)发布了控制机器人手臂和手部的 AI 模型 Liber-0。 在没有针对受测任务的机器人演示数据的情况下,Liber-0 在 60 项新任务的 600 次尝试中完成了 36.0%。在 LiberAI 的测试中,1 万小时的手套数据也胜过 200 万小时的互联网视频数据。 机器人通常要在人们反复引导它完成一项任务后才能学会,而 Liber-0 用超过 220 万小时的人类经验取代了其中很大一部分引导过程。 单靠视频只能看到手做了什么,无法获得机器人必须模仿的实测动作数据。 该公司的 LiberSense Glove 通过在人们工作时记录手部姿态和运动轨迹,提供这些动作数据。 实测动作数据胜过数据量:在条件匹配的实验中,1 万小时的手套数据优于 200 万小时的网络视频数据。 一项策略使用 25% 的机器人演示数据加上手套数据训练后,部分完成度得分为 75.6,高于使用全部机器人演示数据所得的 72.8 分。

This looks like a truly brilliant launch for robot training. Workers wear a thin 131 g sensor glove that records exact hand movements while they do ordinary tasks, so no robot is needed to collect the data. Chinese robotics startup LiberAI (@liberai_robot) released Liber-0, the AI model that controls a robot’s arms and hands. With no robot demonstrations of the tested tasks, Liber-0 completed 36.0% of 600 attempts at 60 new tasks. In LiberAI’s tests, 10K glove hours also beat 2M hours of internet video. Robots normally learn a task after people steer them through it repeatedly, and Liber-0 replaces much of that with 2.2M+ hours of human experience. Video alone shows what hands do, not the measured motion a robot must copy. The company’s LiberSense Glove supplies that motion by logging hand poses and trajectories while people work. Measured motion beat volume: 10K glove hours outperformed 2M hours of web video in matched runs. Trained on 25% of the robot demonstrations plus glove data, a policy scored 75.6 for partial completion, beating 72.8 from all of them.

Introducing Liber-0, our World Action Model for zero-shot robot manipulation—including dexterous, multi-step tasks. Across 60 tasks proposed by GPT-6 and 600 trials, Liber-0 achieved 36% overall success without robot demonstrations collected specifically for those tasks: • Pick-and-place: 63.5% • Other manipulation tasks: 34.0% • Challenging multi-step tasks: 10.5% Zero-shot capability extends beyond individual actions to coordinated sequences. Pretrained on 2.2M+ hours of human experience, Liber-0 jointly predicts future observations and actions to turn human experience into robot skills. Technical blog: https://t.co/X5NMTjsr8r
