About
RUKA is an open-source humanoid hand developed at New York University. It is tendon-driven, has five fingers, and provides 15 degrees of freedom in a human-hand-sized form factor.
The hand was released as a research platform for dexterous manipulation and hand-robot interaction studies. I do not have enough reliable information to state a precise start year, release year, or discontinuation year for this model.
