yeah ... the previous set of arms suit the bot's design a bit better (less is more). But I'm afraid that the judges wont have anything to judge on ... i mean .. 2 pieces of gemotery stuck together for arms ?? hehehe
Now I get to chance to show off hydrolic pistons that actually do things and stuff

Here is a wireframe capture ... it's full of stuff ... I can't even figure all the wires out. But you asked for it

The blocky parts at the shoulder, elbow and wrist are polygons. The cylinders, tubes and balls are NURBS The last 2 knockels on each finger are poly cylinders however (might redo the fingers to remove some detail at the top). The arm patches are SUBDivs (poly hand-patch forgot to convert).
