Terrifying Robots: Part 6

This robot is a mix between adorable and terrifying.  Its slow, almost ponderous crawl forward before it pauses to split open its head and do a little twirl before withdrawing all its limbs and rolling down hill...only to show that on flat land it can easily chase down a little kid.

No I'm just kidding, theres nothing adorable about this thing.  In fact, are you with me in thinking that with the high pitched noise its making, we're looking at the first generation of Screamers?
