I am going to build an Arduino robot. It will move via Continuous Rotation Servos, have a Pixy CMU5 camera for visual recognition, and a small module for short limited Voice Commands.
The robot will have 2 arms on each side of its body.
I am wondering. Where can I find some lightweight, small Arduino robot arms that I could attach to the sides of the robot, and have the robot roll around and pick up stuff with the arms?
Any arm suggestions would be great! 
REMEMBER: Light, and Cheap (because I need two)
I fear that you can have only light or cheap arms, not both at the same time. Both small and light are very relative, the arms have to be at least as long as to reach what they shall grip. The weight of the objects and the length of the arms determine the required torque, and thus the weight of the servos. In a cheap approach the servos are mounted on the arms, including their weight and thus the required torque. A lighter arm approach will move the servos to the base of the arms, and use rods or cables for force transmission.
Video and voice commands most probably require one or more very powerful controllers. I think that you should start small, using any of the available robot kits, until you can determine your more specific needs yourself.
