Aero Hand Open: A Simulation-Ready Tendon-Driven Hand for Dexterous Manipulation Learning

Aero Hand Open is a tendon‑driven, anthropomorphic hand designed for affordable, simulation‑ready dexterous manipulation. The release includes a realistic simulation model of the cable transmission, an identified actuation map that links motor commands to joint motions (including thumb coupling), and a reinforcement‑learning package that trains policies entirely in simulation. These components enable policies to run on the physical hand without fine‑tuning or state estimation.

SoTa: Soft Tactile Skins for Dexterous Manipulation

SoTa is a low‑cost, capacitive tactile skin that offers full‑hand coverage for both humans and robots, featuring a shared layout of 202 taxels across finger and palm regions. The multilayer design with fabric electrodes allows in‑house fabrication for under $10 in materials, and the sensor maintains over 97% of its response after 10,000 loading‑unloading cycles and 1,280 tight‑fist folds. Using SoTa, human‑robot co‑training improves in‑distribution success on three contact‑rich manipulation tasks, and adding human demonstrations more than doubles mean success across eight evaluation conditions, from 22.8% to 45.9%, including all out‑of‑distribution scenarios.

GOTT: Object-centric Dexterous Manipulation with a Reusable Cross-Embodiment Primitive

GOTT is a reach‑acquire‑move framework that uses a single cross‑embodiment contact‑acquisition primitive to enable dexterous manipulation across different robot embodiments. The system first positions the hand near a task‑relevant contact region, then the shared closed‑loop primitive establishes stable contact, after which a pose‑conditioned controller tracks the desired object motion. Experiments in simulation and on real robots demonstrate that GOTT reliably establishes robust contact across diverse objects, arm‑hand platforms, and both seen and unseen hand morphologies, and consistently improves end‑to‑end task success compared to open‑loop grasp execution.
