If you happen to suffer from ophidiophobia (an unnatural fear of snakes), then you might want to wean yourself off this fear with the Omnitread snake robot – don’t worry, this one is non-venomous and will most probably only hurt your wallet if you want one. It comes in two sizes – 4″ and 8″, and wouldn’t seem threatening to anyone at all. The 4″ model tips the scales at around 9 pounds, and can lift half its body above the ground with ease. Apart from that, this robot can expand and stretch its seven segments as and when required, but don’t worry about it shedding as it will only rust instead.
