Sentry 5

"After doing battle with invading aliens, Sentry 5 is grateful to be whole again thanks to tibial implants for legs, medical rakes for hands and a shiny, brand-new taxidermy eye," Avitzur says. In fact, the eye comes from a lion and has an LED behind it for a menacing look. The robot's body is an old whipped-cream maker, its arms are from citrus presses and its hands were made from surgical retractors.
