The RH5D and RH7D are child size, anthropomorphic hand models with opposable thumb control.

Both models have the same external dimensions and design and the internal electronics are also the same. FOr this reaosn documentation for both models is combined.

The difference between the two, is that the RH5D lacks the Wrist flexion and Wrist Adduction Degrees of Freedom (and the corrsponding actuators). The RH7D has these Degrees of Freedom and as such offers a full spherical wrist joint.
