The Robotics Stack

Billions are going into factories to build tens of thousands of humanoids. Matt Trossen has sold robot hardware for 22 years and cannot name one customer who wants to buy one. youtu.be/hGnw6zzW5Nw

You want to train your humanoid fully in sim and deploy zero-shot. Then your actuator behaves nonlinearly and the whole plan falls apart. We sat down with the CPO behind Asimov, the open-source humanoid, on @roboticsstack New episode 👇 youtube.com/watch?v=96lFS1O1…

An openai intern gave GPT-6 Astra a cheap 3d printable arm, a paintbrush and two cameras, then told it: paint the golden gate bridge. Astra worked out the arm itself, then started correcting its own errors. Six astra robot demos on @roboticsstack youtube.com/watch?v=hshlKEuR…

Numb your fingers and good luck trying to light a match. That's a robot hand today Matt Wulff @makeitmatto, cofounder of @6thSensedev, on why he thinks touch is the missing modality, studio-recorded data is fishy, and UMI is not here to stay. New episode youtube.com/watch?v=6rY_Iqv4…

What happens to US robotics if Unitree gets banned? Randall Briggs left MIT to build Steel Bot, an open-source, made-in-America humanoid. We talk specs, modularity, hands, funding, and what it really takes to mass produce one. New episode out now 👇 youtube.com/watch?v=UJeTRAqy…

A chinese humanoid company is now selling an AI companion with silicone skin, 88 DoF, and an LLM that reads 20 emotions. 13,000 orders at launch. We dive into the AI companion market on @roboticsstack, including the cyber brothel that opened in Berlin. youtube.com/watch?v=nceLG4K_…

The Asimov 1 by @asimovinc might be the first real open-source humanoid. $20k for the kit, $499 to pre-order, 100+ hours to build it. Employee-owned, no VC. Also: @DynaRobotics's new model, @trossenrobotics, and thoughts on robotics margins. youtu.be/xobT0PgxKAA

Gemini Robotics 2 can unscrew a light bulb 92% of the time. But screwing it back in? 36%. We cover Google's new models, + the top 10 robotics companies by revenue, why plugging ChatGPT into a robot doesn't work, and robot fights. New episode 👇 youtube.com/watch?v=mTpMiW_W…

Every humanoid joint you've seen is three motors stacked on top of each other, each one carrying the weight of the last. We sat down with @CianciottoBryce, who built the Orbit Actuator that does all three axes with the motors at the base. New episode 👇 youtube.com/watch?v=AFOMl8Z9…
