I can think of two possibilities for arms.
Moving arms presents a problem of torque at the joints (shoulder, elbow)
that quickly increases with speed. This can be reduced somewhat by using
lighter materials other than your standard bucky type skellie has for arms. Maybe substituting blucky arms for example.
Use a wiper motor or monster servo to push/pull a cable or cables or heavy duty servos (metal gear) or 1/4 scale servos at the joints.
You could also use a wiper motor or monster servo with a pulley to raise/lower the arms and then supplement elbow and wrist movement with smaller servos.
