Real-time communication with precise timing across multiple drives. • RS-485: Joint motors. A noise… - [@techniahqrobot on X](https://x.com/techniahqrobot/status/2111917599676350693) You can build a dexterous robotic hand for just $314. Prefer it ready to use? The fully assembled version costs about $720. Chestnut Robotics' Aero Hand Open weighs 389 g and has 7 active degrees of f… - [@chris_j_paxton on X](https://x.com/chris_j_paxton/status/2109748959996469664) My biggest takeaway from IROS was about hands and dexterity. It used to be so hard to do meaningful work with hands -- and it's still hard, these systems are fragile and expensive, but it's so, so muc… - [@michellelsun on X](https://x.com/michellelsun/status/2109712878320443421) Dexterity is the frontier for robotics today Great writeup by @chris_j_paxton - that was my main takeaway from IROS as well https://t.co/dvt1X3b7QI - [@chris_j_paxton on X](https://x.com/chris_j_paxton/status/2109647690250568127) Some thoughts on a robotics conference: the research community increasingly is looking at enabling contact-rich manipulation with dexterous hands, and has the tools to do so https://t.co/zZhiEHLX49 - [@ZappyZappy7 on X](https://x.com/ZappyZappy7/status/2108320128740040751) 『拡張性の高い人体操作データ収集用外骨格』 https://t.co/WOKWHxFjii #exoskeleton #manipulation #DataCollection #PhysicalAI #UMI #interface #WearableDevice #AeroHand #ChestnutRobotic https://t.co/qCm1E6HlIw - [@TheHumanoidHub on X](https://x.com/TheHumanoidHub/status/2104657379770118214) UMI, but for humanoid hands. UMI-style capture already works great for simple grippers. For a high-DOF hand, where the action space is huge and contact force carries the important signal, matching the… --- Source: Roboterminal · https://roboterminal.app/companies/chestnut.md
