Whether they slink along like a human, jog like a dog, or slither like a snake, some robots are creepier than others.
Our top five creepy robots include "the dog" from Boston Dynamics, a packhorse-like machine that can carry military hardware in rough terrain. Watch it trot along, it's far too much like a friendly pet not to be disturbing.
The Russians have eerie bots nailed, with their indomitable forest-crawling hexapod machine. That beast looks like it could march straight into your house, without wiping its metallic feet, and rip your heart out before it even broke stride. All it needs is some pincers on the fron, and you can probably choose those as an optional extra from the dealer.
Robot fish are a match made in electrocution hell. Plus, that shark is enough to make us jump out of the water - it's that realistic.
