A 20-DoF humanoid robotic hand for humanoid platforms and advanced research. It is listed with 20 hand DoF and 0.6 kg weight; availability is unknown.
I do not have reliable historical information about Robotis HX5-D20 beyond the brief technical description provided here. It appears to be a 20-degree-of-freedom humanoid robotic hand intended for humanoid platforms and research use.
Because I cannot verify a launch year, deployment history, or discontinuation date from my available knowledge, I’m leaving the timeline empty rather than guessing. If you have a datasheet, catalog page, or press release, I can turn that into a proper chronology.
