W Robot
Noguchi, Early 1960s
6.5 inches tall

Conical, with a large sparking window on its chest, the W robot stands out from its peers' angular designs. No one really knows what the large W on the robot's chest stands for; the Doctor likes to think "Wanton," on account of the fact that this is one of the only two robots that has a pair of ass cheeks. Sexy.

In action, the robot rolls foward while its chest sparks.

A number of knock-offs exist from Greece and Argentina, and both are easy to identify: the Greek version has a Greek symbol instead of a W, and the Argentinian robot is labeled as such. There are also a few other Japanese variations with different arms, and a much rarer one that features a gell with a space scene on it in the sparking window.
