最近,Microduck 在黄教主 @JensenHuang 的 GTC 互动中又大火一把,相关视频在社交媒体上获得了广泛的转发
但是,这些视频有严重的误导性,确实会让绝大多数的人以为 Microduck 能听懂人话,会自主执行任务
Microduck 的一个工程师 @RemiFabreRobot 为此专门发长推,做了一些演示真相的澄清说明
· Microduck 非完全自主伴侣,主要是靠遥控指令执行任务,所以 GTC 上每只都是后台的工作人员在遥控
· 当前自主只是底层的运动,如行走、起身和空翻等,通过强化学习实现身体平衡和抗扰动动作
· 官方提供的开发平台和模拟器环境,供社区训练新步态和动作策略
全自主机器人所需的算力在当前配置上是无法实现。
所以消费者需要知情一下,免得到手后会有过大的心理落差
This live demo of four Microducks with Jensen Huang went completely viral, and we're ecstatic about it. But there's also a lot of confusion, so I want to clarify what Microduck can and cannot do, and what it will realistically be able to do in the future.
I count 60M+ views on this demo alone, based on the few big posts I see on social media, and everything has been buzzing. Even my own simple emotional design post on a newly created Instagram account got 1M+ views. We are selling Microducks at an incredible rate, even faster than during its historic launch. I've been trying to answer all the questions I see on our socials: people are asking if X or Y is possible on the robots, and this post aims to answer most of them.
First of all, the demo you've seen was not fully autonomous. We had one engineer piloting each Microduck. The motions on the robots were trained with reinforcement learning, using a sim-to-real pipeline: walking, standing up after a fall, sitting, doing a somersault, roller skating. All of those are policies trained this way. What the pilots did during the live event was send commands: directions (move forward, rotate), head orientation (look here), quacks, and special actions (do the somersault, sit down).
If you buy a Microduck, will you get an autonomous companion right out of the box? The current answer is no. But there is no impossible technical barrier to get there. I'm not sure how much time we'll have to work on this before shipping, but since everything is open source, I fully expect the community to build it, and to build it fast.
Now let's understand what's already done, what will be easy to add, and what's an open problem. What you'll be able to do out of the box, and you can already do it in simulation right now, is train new policies with reinforcement learning. You could teach your duck to walk differently from the default gait we provide, to do a weird dance, or to walk on stilts. The community has been crazy creative with this, even though they only have the simulator.
Note that you don't need reinforcement learning when the movements are simple. For example, the early emotional design I did is mostly coded movements plus pre-generated sounds. A simple mental model: use reinforcement learning when balance is part of the movement. If you try to code a cinematic walk by naively putting one foot in front of the other, your robot will realistically never walk, because you need to account for the dynamics of the movement, the inaccuracies of the sensors, the friction with the ground, and potential perturbations from the outside, like being pushed.
So training new policies is definitely doable, but you can't train a policy to get a genuine long-term companion in your home (well, technically you could, but that's a whole other range of policy: a research-grade problem, and the resulting neural network would probably be huge and never able to run on such a small compute). Instead, you need a few more building blocks: voice recognition, facial detection/recognition, localization, some simple navigation, and a behavior layer, which is less technical and harder to describe.
As a rule of thumb, a prototype of any of these is within reach of anyone if they have a modern coding agent and if the computation doesn't run on the robot (meaning the robot can reach the internet or an external computer and use external APIs). A rough prototype for each of the above can be a chill weekend project. As always, going from the prototype to a high-quality implementation is another story, but still doable for most if you put in the time and test a lot.
However, having all of this run locally, on the onboard chip, I would call a very hard task. You'd need some very clever engineering to get a good enough version of everything working together. But I can't say it's impossible, because I've seen some crazy efficient implementations of all of the above. And here we don't need a super high success rate: it's okay if the duck sometimes does something a bit random. So I wouldn't be surprised if folks managed a fully local, cool, simple version of this autonomous companion. For example, you don't need Whisper-grade open-vocabulary transcription: being able to recognize a few keywords would already be great for interaction.
One of the fastest ways to turn this robot into an autonomous companion would be to stream Microduck's sensors (the camera, the depth sensor, the IMU and the joint positions) to a computer, and use a software stack like the one we use for the conversation app on Reachy Mini: a local VAD, then a cloud speech-to-text model, then a call to a frontier LLM that decides on actions. Actions could be quacking, looking at things/faces/a direction, walking to a given position, sitting down, playing an emotion, kicking or doing a somersault. A SLAM algorithm would run in parallel so the robot can localize itself in your home, and you would prompt the LLM for a lifelike behavior: moving to random places, sometimes following people, and having emotional responses that fit what you're saying and the duck's environment. Of course someone is going to build a Tamagotchi-like layer on top of this, and it will be insane.
How much demand is there for a software suite that would do all of this? I for one think it would be super cool.
A word about the humans. We had five engineers backstage, and they are pretty much the core team behind Microduck. Their impact per head is absolutely off the charts. Antoine Pirrone piloted Graphite, Augustin Crampette Lavender (the rebel one), Matthieu Lapeyre Sky, Coralie Deplane Cream, and Pierre Rouanet was stressing over the Wi-Fi. Give them a follow! (Antoine @antoinepirrone, Augustin on LinkedIn, Matthieu @matth_lapeyre, Coralie @Drenaya_, Pierre on LinkedIn).
I get visibility because I communicate a lot, but I mainly work on Reachy Mini (you might want to check it out: it's a very cool robot, and it ships much faster than Microduck :) ). My contribution to Microduck has been minimal: I'm mostly a first power user. My main added value at GTC was having hands big enough to carry four Microducks below the stage.
Where I take pride is that Antoine and Coralie are former students and former interns of mine. I'm therefore entitled to 3% credit on anything (good) they do, for life. If they do something bad, however, it was clearly the fault of their parents.
About the super smart engineering that can be done on board: Antoine just released two very cool blog posts (links below). The first is on odometry, the robot estimating its own movement from its own internal sensors. The second is about SLAM, which allows long-term localization: it adds the depth sensor to the odometry to get a stable position over time. Think of it as recognizing known landmarks in your home to know where the robot is. The crazy part is that all of this runs on the robot. So this gives me hope that we'll be able to do a lot of cool stuff on board.

Hey @trq212 ,见字如面!
犹豫良久,还是发了这封不太适合现在发的邮件。
我知道你是因为反对 anthropic 的反华政策,才义无反顾的辞职。
现在,你可以放心公开 Claude 具体的封号检测机制,以抵制这个反人类的企业。
只差这一步,勇敢站出来,你就是个大英雄!
最好的祝福

I’ve left Anthropic after more than a year of working on Claude Code and seeing it scale larger than I ever imagined.
I have really loved working at Ant and believe deeply in the mission, and most of all, the idea of a race to the top.
The idea that if we work hard and responsibly, we can raise the bar and inspire others to great outcomes. And if we all push each other to be better, things can be radically good. I will carry the spirit of this with me forever.
My colleagues at Anthropic are the most talented, thoughtful, competent, and earnest people I have ever met. I am glad they are at the wheel and trust them deeply.
To the community on X, thank you for everything. You’ve made this the most fun (and sometimes stressful) job I’ve ever had.
For me, it is time for a bit of a break before diving into something new.
If you want more excellent Claude Code content, you should follow @addyosmani , @lydiahallie, @_catwu, @ClaudeDevs and of course @bcherny who started it all.
Kimi 市场部门知道中区博主有情怀,默认都会夸自家的开源模型,根本不用花钱请
当然也有一种可能是:中区的商业推广帖子,商业太重,只要不傻一眼都能看出来
所以,Kimi 都找海外的大V来大肆宣扬新版本
没想到这次没把控好,被暴露了细节
That's how Kimi AI are promoting their new model Kimi K3.1 pro and I know all the influencers working with them and none of them are honest,I have posted about it myself but I didn't join this and never used their templates that they provide.
PROPAGANDA, I have more to share it's f**cked up I'm gonna have follow up for this
