By now you’ve probably heard of Simone Giertz, the queen of “shitty” robots. And, man, do her robots suck.

Her latest robot might be her worst (or best) work yet.

She uses two robotic arms to try to make herself a peanut butter sandwich. One of the arms holds a plastic knife for peanut butter spreading, while the other robot arm, controlled off camera by assistant Fiona Rolander, moves to cue identical motions for the knife-wielding robot.

What ensues is pure insanity, with the robot slinging the bread off the table and spreading peanut butter on just about everything but the bread.

If you haven’t checked out Gertz’ previous work, we highly encourage you to do so. We’ve already seen her robot slap people awake, “wash” her hair, and a robot that lets everyone know they should deal with it.
