The arm, at least the first release, will have three degrees of freedom, so we'll need three servos: Two for the shoulder and one more for the elbow.

I chose to use small, light and cheap servos for the prototype, as it won't move heavy loads. So, I ordered 5 Mystery Micro Servos in e-bay:

I bought them in (and took the picture from) RC-Timer.

They won't probably be very hard, but they are really cheap and will be useful to test my ideas. If things go well, I would probably buy some Futaba servos, with metal gears and able to pick up heavier loads. This mystery micro servo has a stall torque of 1.2 kg*cm and each one weights 9g, that should be more than enough to move the arm parts.

I expect them to arrive in a week or two, so we'll see what can they do...
