For real customers in real deployments, reliability is the spec that matters most — and one of the hardest problems in dexterous hands. It's what we've engineered for from day one. Tendon-driven, every actuator sealed inside the palm: a hand built to survive millions of cycles on the test rig — and the accidental mishandling that real work inevitably brings. Durability is the foundation. Our other core advantage is data — not more data, but higher-fidelity data, captured at sub-millimeter precision. Our co-founder & CTO Joe Dong walks @TheHumanoidHub through both ⬇️ See it live at #WAIC2026 next week.

We keep hearing the same thing: dexterous hands break. Usually by accident, and even experienced developers slip up sometimes. So we tested its most fragile part, the fingers. Repeated impacts, harder each time. Aero Hand Open held. Reliability you can build on.

@iamRezaSayar Thanks for watching so closely, we really appreciate it. We've made a small tweak to the wording so it lines up more precisely with what's in the clip.

@ChestnutRobotic impressive video! but doesn't match description. what i see: hand fishes for a bunch of screws, not one, and then drops them into another container.end. the screw already placed right and only needing to be fastened and the already tool grasping hand approaches and does the job.

Early in-house test. Task 1: Aero Hand Open grabs a handful of screws from one bin and drops them into another. Task 2: with a power screwdriver, it fastens a screw on another hand. 1x speed. Robot, hand, and policy are all ours.

First SLAM navigation test of our wheeled humanoid , running through the office @ChestnutRobotic . U-turn included, no human in the loop. Wheels first. Hands next.

That's our Aero Hand Open running in this active UMI rig. we kept it under 400g and packaged all the motors inside the palm so it mounts onto any wrist with no kinematic re-tuning. handheld setups like this were one of the use cases we built around. great to see it in this kind of build. @kukreja_abhinav ping us if you need any further support, dms open.

High-quality dexterous robot data is expensive to scale. That is the bottleneck we are focused on at Chestnut Robotics. As our co-founder and CTO @JoeDong233873 puts it, our approach is to convert human dexterous manipulation data into robot-quality data, starting from structured industrial environments where robots can create real value first.

Finger tutting looks easy until you try to engineer it. Every finger moves on its own axis. Every joint hits the beat. The palm holds steady through all of it. So we built a hand that could. Built to work. Also built to dance.

Dexterous hands work great in controlled settings. We wanted to know what happens when the environment fights back. So we let a toddler loose in the living room, then gave the Aero Hand Open one instruction: "put the toys back in the bin." Fully autonomous from there. VLA model perceives the scene, plans each grasp in real time, adapts finger trajectories to objects it has never trained on. Stuffed animals, toy trucks, rattles, all soft and irregular, scattered randomly across a play mat. No fixtures. No staging. Just a real room, real mess, real manipulation. Fully open source. #robotics #embodiedAI #opensource

Sunday just raised $165M 🤖 This validates UMI-based in-the-wild data collection as THE winning strategy for robot manipulation. But picking up objects is just the beginning. Next frontier: dexterous manipulation → In-hand reorientation (rotating a pen, unscrewing a cap) → Tool use designed for human ergonomics (scissors, screwdrivers, knives) → Contact-rich bimanual coordination (tying knots, opening jars) The hard part isn't the model architecture — it's capturing rich hand demonstration data at scale. Whoever builds the best glove + multi-fingered hand capture pipeline wins. Same UMI playbook. Much harder input space. 🦾 #robotics #dexteroushand #humanoid

We have some exciting news to share! 🚀 Today, TetherIA is officially rebranding to Chestnut Robotics. 🌰🤖 As our focus on advanced robotics has grown, we realized we needed an identity that truly reflects our vision for the future—sturdy, grounded, and innovative. Same dedicated team. Same core mission. Brand new look. Welcome to the next chapter. Let us know what you think of our new logo below! 👇 #ChestnutRobotics #Rebrand #Robotics

1,000+ units shipped. Zero marketing spend. Aero Hand Open is proving that in robotics, product speaks louder than ads. Every hand you see here found its way to a lab, a factory, or a research team — purely by word of mouth. This is just the beginning. #DexterousHand #Robotics

100% behind our CEO @Evan_Tao_T.We’re building the full stack to unlock real-world dexterous robotics, with official deployment coming in 2026.Follow us for every step of this journey. #robotics #AI #buildinginpublic

Respect, Remi! Seeing you push our hand to its limits is exactly why we built it. Let’s skip the small talk and dive into co-creation. What’s your next wild move? We’d love to team up and build something truly insane together. 🦾🔥

@GoingBallistic5 Love your deep dives on humanoid hands. We’re @TetherIA_ai building Aero Hand Open—a low-cost, open-source, tendon-driven dexterous hand. Would you be open to a quick chat or hands-on review? DMs seem closed—what’s the best way to reach you? tetheria.github.io/aero-hand-open/

We'ave seen the future

We spilled grapes and blueberries all over the desk… so the robotic hand had to clean it up 🍇🫐🤖 Small, slippery objects are a real dexterity challenge — but the tendon-driven hand picks them up one by one under webcam-based teleoperation.
