This is an antique metal robot. His arms, waist and antenna can all be repositioned. He does have a battery compartment in the back, but if you look at the pictures, there is some rusting. I do not know if he works or not as we have only ever used him as a display. A very unique item for any house 12” H x 6” W x 4” D - measurements are approximate Dog friendly home.
