启动 HN：Vassar Robotics（YC X25）——售价 219 美元的机器人手臂，能够学习新技能
嗨，HN——我是来自Vassar Robotics的查尔斯（<a href="https://vassarrobotics.com">https://vassarrobotics.com</a> - 网站内容不多，但您可以在<a href="https://shop.vassarrobotics.com/products/navrim-robot-that-learns-skills-in-30-minutes">https://shop.vassarrobotics.com/products/navrim-robot-that-learns-skills-in-30-minutes</a>上订购机器人）。<p>我们将推出升级版的SO-101机器人手臂，定价为219美元，具备改进的机械设计和增强的智能。<p>您可以在这里查看它的功能：<a href="https://youtube.com/shorts/xNyPKJZI400" rel="nofollow">https://youtube.com/shorts/xNyPKJZI400</a>（演示视频已加速播放）。<p>我花了几年时间制作遥控飞机（<a href="https://cyo.ng/hangar" rel="nofollow">https://cyo.ng/hangar</a>）和微型燃气涡轮（<a href="https://set.mit.edu" rel="nofollow">https://set.mit.edu</a>），我一直希望硬件能够更便宜，这样更多人就能进行实验。<p>现在，我推出了一款219美元的桌面机器人手臂套件，保留了LeRobot SO-101的运动学，替换了关键部件以实现更坚固、更精确的SLA打印，并增加了两个集成的480p摄像头。经过多次与供应商的讨价还价，整个套件的成本甚至低于仅仅十二个伺服电机的价格。我将在6月30日前以MIT许可证发布更新的机械设计。<p>在软件方面，我还将在6月30日前发布一个MIT许可证的MCP服务器，向代理LLM（如Opus 4、o3等）提供本地机器人策略作为工具，以便在长时间任务中使用。其工作原理如下：您可以通过遥操作教机器人新的技能。在推理过程中，您只需使用自然语言指令与代理LLM对话。LLM随后通过MCP调用本地机器人策略，自动将您的高层请求分解为可执行的机器人命令。<p>感谢LeRobot社区让这样一款出色的机器人变得触手可及。如果您曾为LeRobot的GitHub仓库做出贡献，请发送电子邮件至hello@vassarrobotics.com，获取一张20%的折扣券，以表达我的小小感谢。<p>我非常希望听到您的反馈！除了制造、清理代码库和编写文档外，我还在考虑：一个力控夹爪、一个平行夹爪、一个额外的腕部自由度（与新的Trossen和ARX手臂匹配）、主手臂的全力反馈（尽管这可能会使价格翻三倍）、一个每个关节分辨率较低的更实惠版本，以及一个更长的变体。您觉得哪一个，或者其他什么，会对您最有用？<p>如果您想订购，可以在这里下单：<a href="https://shop.vassarrobotics.com/products/navrim-robot-that-learns-skills-in-30-minutes">https://shop.vassarrobotics.com/products/navrim-robot-that-learns-skills-in-30-minutes</a>。<p>期待您的任何评论！

Hi HN — I’m Charles from Vassar Robotics (<a href="https://vassarrobotics.com/">https://vassarrobotics.com/</a> - not much there but you can order the robot at <a href="https://shop.vassarrobotics.com/products/navrim-robot-that-learns-skills-in-30-minutes">https://shop.vassarrobotics.com/products/navrim-robot-that-l...</a>)<p>We are bringing an upgraded version of the long beloved SO-101 robot arms to a $219 price point with improved mechanical design and added intelligence.<p>See what it can do here: <a href="https://youtube.com/shorts/xNyPKJZI400" rel="nofollow">https://youtube.com/shorts/xNyPKJZI400</a> (demos are sped up as shown in the video)<p>I’ve spent a few years building RC planes (<a href="https://cyo.ng/hangar/" rel="nofollow">https://cyo.ng/hangar/</a>) and micro gas turbines (<a href="https://set.mit.edu" rel="nofollow">https://set.mit.edu</a>), and I’ve always wished hardware were cheaper so more people could experiment.<p>I’m now launching a $219 desktop robot-arm kit that keeps LeRobot SO-101’s kinematics, swaps key parts for sturdier, more precise SLA prints, and adds two integrated 480 p cameras. After plenty of supplier haggling, the whole kit costs less than the twelve servos alone. I’ll release the updated mechanical design under an MIT license by June 30.<p>On the software side, I'll also release an MIT-licensed MCP server by June 30 that exposes the local robot policy as tools for agentic LLMs (Opus 4, o3, etc.) to use in long-horizon tasks. Here's how it works: You can teach the robot new skills through teleoperation. During inference, you simply talk to the agentic LLM using natural language instructions. The LLM then calls the local robot policy through MCP, automatically decomposing your high-level requests into executable robot commands.<p>Thanks to the LeRobot community for making such an amazing robot accessible. If you’ve contributed to the LeRobot GitHub repo, email hello@vassarrobotics.com for a 20% discount coupon as a small thank-you.<p>I’d love your feedback! Beyond manufacturing, cleaning up the codebase, and writing docs, I’m considering: a force-controlled gripper, a parallel-jaw gripper, an extra wrist DOF (matching the new Trossen and ARX arms), full force feedback on the leader arm (though that may triple the price), a more affordable version with lower resolution each joint, and a longer-reach variant. Which of these—or something else—would be most useful to you?<p>You can order it here if you want: <a href="https://shop.vassarrobotics.com/products/navrim-robot-that-learns-skills-in-30-minutes">https://shop.vassarrobotics.com/products/navrim-robot-that-l...</a>.<p>Looking forward to any and all comments!
