The Robot Studio is the French open-source design studio of Rob Knight in Villeurbanne, publishing 3D-printed robot designs. Its best-known projects are the DexHand, the low-cost SO-ARM100 arm and the HOPEJr humanoid that uses these hands.
The officially documented hand is V1.0 with 19 powered degrees of freedom and about 300 USD in parts when self-printed; a second line lives in the V2_DexHand repository under CERN-OHL-S, and the entry DexHand V2.3 describes the state of that documentation. The studio does not sell assembled units but shares its files on GitHub.
