We co-designed a three-finger 8DOF robotic dexterous hand and together with its isomorphic exoskeleton, people can wear this exoskeleton to control the dex-hand easily and naturally, or use it as a single data collecting device.
We started this project three months earlier, when Dex-UMI ( CoRL 2025 best paper finalist ) was published, yet aiming at the future-work direction mentioned in Dex-UMI.
We 3D-print a so-called toy model to test if this version's design meets the requirement—executing our defined set of 10 in-hand dexterous manipulation tasks.
Its moving parts are pin-connected ; assembling each new toy model is like snapping together a Lego brick 🤣

We designed and built a low-cost VBTS module, with a BOM cost of only ~200 RMB. It is highly modular and easy to integrate into a gripper, requiring only a single USB 2.0 cable for power and data streaming—plug-and-play.
In just 3 months part-time, we finished this project and integrated this module onto DISCOVER Robotics' two-finger gripper, already delivered 20 units in small batch, and generated 200,000 RMB in revenue for the company.

close-loop verification for each tech-part
Every component is available on Taobao, with a BOM cost of only ~200 RMB.
