How Do Nao'S Hands Work?

I would like to know how NAO's hands work (if anyone knows). He only has 25 servos (one more than my robot) yet can independently open/close each hand. If anyone knows how, i would like to know! thanks.

EDIT: What I'm asking is how one servo can operate two hands independently if all the other servos are used for his body movements.

Here are the servo counts:

  • Arm 5 DOF in each arm

  • Pelvis 1 DOF

  • Leg 5 DOF in each leg

  • Hand 1 DOF in each hand

In addition to @doc's post,

Each hand has it's own servo.
