Why is it they always say these things will be used for "rescue searches in rubble" when we all know damn well that the only search they will be conducting will be the search for human blood to power their souless bodies.

if I were trapped under rubble and I saw that thing coming for me I would not feel very safe

Isn't that the same basic sensor setup that pinworms use to crawl inside your anus? Can't see anything going wrong there.

I have to insist that we find a way for robots to feel sympathy before we start giving them important tasks.

I associate that sound it makes with a robot from an SF film, but buggered if I can remember which.

Also, I already have a cat, do I need a robot one?

Awesome, a robot that can sniff your eyeballs while you sleep, like my cat does.
