We have a huge news to share today!
Today we are unveiling the first truly accessible RL robot - welcome Microduck
A 25 cm tiny open-source biped with 15 actuators and packed with sensors (camera, speaker, LiDAR, NFC, bluetooth, wifi, etc) that you train yourself with reinforcement learning.
It's also playable out of the box with more than half a dozen fun and playful pre-trained policies to have it walk, sit, crouch, roller-skate, pick up objects with its articulated beak, and recover on its own.
And all for less than $400.

Modern FPV drone architecture explained in one simple diagram! 🛸⚡
Whether you are building custom quads from scratch or working on industrial automation and drone electronics, understanding the core stack and component layout is key.
Here is a quick breakdown of the essential components that power a modern FPV build:
Flight Controller (FC) & 4-in-1 ESC Stack: The central brain processing sensor data and managing precise power delivery to all four motors simultaneously.
Power Capacitor & XT60 Connector: Protects sensitive onboard electronics from voltage spikes and ensures clean power distribution during high-draw maneuvers.
Control Receiver (RX) & Video Transmitter Antenna: Handles low-latency RF signal reception for control inputs while transmitting real-time visual feeds.
Brushless Motors & FPV Camera: Delivers high RPM responsiveness coupled with durable camera housing for tight maneuvers and clear telemetry.
Having a clean, efficient layout isn't just about aesthetic wiring—it directly impacts signal noise, heat dissipation, and long-term hardware reliability.
What’s your preferred FC and ESC stack setup for custom builds? Let’s discuss in the comments! 👇

Lovable 的设计负责人 Felix Haas 在社交媒体上分享了一篇关于"AI 时代高效团队"的观察,七条经验总结,来自这家增长速度惊人的 AI 创业公司内部视角。
几条有意思的观点:
第一,别像员工一样等安排。影响力最大的人不问"这归谁管",看到问题直接上手。主人翁意识不是靠分配的,只能靠自己拿。
第二,招人看态度不看简历。技能当然重要,但光有技能几乎不能预测一个人能不能成事。真正跑出来的人靠的是好奇心、韧劲和学什么都愿意学的心态。在 AI 时代,这一点比过去更明显。
第三,好奇心和沉迷 AI 是两回事。真正用好 AI 的人不是天天刷资讯,而是不断去试那些没人让他试的东西,追那些可能根本走不通的想法。大多数人不会这么做,但少数坚持的人,回报是指数级的。
第四,让资深的人重新动手。这是 Haas 觉得最有意思的现象:经验丰富的管理者重新变成了 builder(建造者)。AI 让个体贡献者的杠杆效应急剧放大,一个深度使用 AI 的资深工程师或设计师,可能是当下公司里最强大的组合。
第五,自我意识是速度的敌人。Haas 说他从没见过自我意识让公司变快,但见过它让公司变慢。最快的团队不太在意谁拿功劳,只在意什么方案有效。
第六,先发布再迭代。一周的内部讨论,抵不上一天的真实用户反馈。最强的团队不追求发布前完美,而是追求尽快学到东西。发布本身就是他们学习的方式。
这些观点单独看并不新鲜,不过 Lovable 这两年发展的确实不错,2024 年上线,8 个月做到 1 亿美元年收入,2025 年底完成 3.3 亿美元 B 轮融资,估值 66 亿美元,是欧洲增长最快的 AI 公司之一。
尤其是“让资深的人重新动手”这一条,可能是 AI 时代最容易被忽视的组织变化。当 AI 工具足够强大,过去被提拔到管理岗、远离一线的高手,重新获得了亲手做事的能力和动力。
