最近axis robotics其实有一些非常amazing的进展。还没形成paper，但是先简单分享一下激动的心情。 简单来说，过去一年，通过axis社区的数据贡献，我们其实积累了大量manipulation的动作轨迹数据。 但是我们逐步发现，这些数据更大的价值不是直接拿来训练某一个通用大模型，而是作为先验，告诉我们哪些特别的动作和状态值得探索。 最近，我们依靠 LLM 自动化生成场景和任务，然后在这些用户数据和少量自动生成数据的基础上，我们可以用高速、低成本的 RL，把每一个任务快速训练成一个接近 100% 成功率、覆盖大量状态变化的专项 Expert。 这个expert，你可以理解为是axis自研的针对某个特别的动作的专用模型，它专门针对这个任务场景可以取得非常强的泛化能力。 这些 Expert不仅具备很强的泛化能力，同时也可以通过物理和视觉随机化充分利用 Simulation，并进一步迁移到真实机器人，同时持续生成大量高质量、多样化的训练数据。 当我们把这个过程复制到成百上千个任务以后，就得到了一整个专家模型的Network：装箱、分拣、抓取等不同任务都有自己的强 专家模型，再把这些 Expert 的能力和数据统一蒸馏、fine-tune 到一个共享的 Foundation Model 里。 也许有一天，axis也拥有属于自己的海量专家模型甚至做出来属于我们的foundation model。how exciting it is

We prepared 18 tasks that were expected to be finished within a week, and they were all completed within 24 hours of launch. This all comes from people's conviction that simulation is a key way to solve the data scarcity in today's physical AI development. Axis has not announced any VC backing yet, and we haven't done any paid marketing. All user growth has been organic, coming from loyal community members who truly believe in what we do and what we are here to achieve. I appreciate everyone's patience and passion for Axis Robotics. Your contribution is valuable. The issue with "task not completed" came from our mission checker being too strict. We are on track to solve this in two ways: 1, We will try to highlight the region in red in the future to provide clear guidance for the mission completion range. 2, We will see if we can provide a tutorial video for each task. keep buidling~
