As pet robots go, we can't exactly say this one is the cutest or cuddliest. In fact, we can't even say what it looks like at all, except for maybe a giant shark tooth.
But to hear the Taiwanese Industrial Technology Research Institute tell it, this is actually a robotic fish with the unlikely name of "POPO," according to I4U News. POPO can reportedly swim on its own for 24 hours on its rechargeable batteries without bumping into things because of its ultrasound system.
That's all well and good, but we think they could have at least painted a pair of eyes on it or something.
