Artist Alan Westby has made a series of wood automata depicting robots. They are beautifully made, with finger-jointed cherry boxes, laser-cut wood gears, and carefully assembled geometric shapes. The entire series is cleanly construction. At the same time, it is playful as well. Westby's wooden robots are engaged in domestic scenes, space scenes, flying airplanes, and various other shenanigans.

And just to prove my point that wooden robots are taking over the world, here are a bunch that you can buy -- but never truly control -- on amazon.
P.S. If you've never seen it, here's my own contribution to the wooden robot genre from 2007.
