A robot that can plug itself in would be totally unstoppable — as long as the power was turned on. It's like a cat who knows how to work a can-opener. German artist Andre Kutscherauer's 3-D CGI images show manic bots that look like Pixar's mutant offspring. My favorite image is the one below, showing a lightbulb bot that's plugged itself in — and now faces some unfortunate moth trouble.

This is quite funny,I dont know how usefull it is but it could help when you're not in the mood to do anything.
