Looks like a uArm style arm.
Pretty sure the four 9G servos are not included, but the hardware (screws & such) is. BYO controller.
I still like Hobby King's HXT900 servo, although metal gear servos might be best for at least the two shoulder joints (heavy loads).
Ken, I still say Parallax ought to sell an arm kit like this. Sure would look great on top of an AB or S3!
"When you make a thing, a thing that is new, it is so complicated making it that it is bound to be ugly. But those that make it after you, they don’t have to worry about making it. And they can make it pretty, and so everybody can like it when others make it after you."
