Lifelike robo-fish at Tokyo Toy Fair

Next time my kid asks for a pet fish, I'll get her one of these instead. It's better than the real thing.

Created by TakaraTomy Arts and released at the 2012 Tokyo toy fair, this cute gizmo costs 15 € a pop. it runs on batteries that power the fish's tail. it then moves randomly on it's own, with its tail respectively moves slower or faster.

  1. OK, score another for the Japanese on the cool toy front. Make those solar powered (keep a UV light on the tank) and these things would be perfect.

  2. I was hoping one of you commenter-geniuses would explain how random fin activity might produce apparent random buoyancy (assuming the toy lacks tiny ballast tanks); but so far you-all have proved a disappointment [finger-wag]

    1. They appear to be slightly lighter than water but also front-heavy, which causes them to point slightly downward.  Thus, when the fin flaps, the fish dives deeper into the water, but when the fin-flapping subsides, the fish rises.

      That’s my guess anyway.

  3. Anyone else get the chills from these?  Yeah, I think they’re brilliant, yeah, I’d buy them.   But they do trip my piscine uncanny valley spot.   

  4. Wow, these will be great for the “split second after I passed 20,000 volts through my pond” display I’m working on. That kind of involuntary twitching death throe is very hard to reproduce.

  5. Ok, so what I need right now is a robot version of me to go to work and do my job. He will be a compliant, hard working team player who does not complain. Meanwhile I can stay home and read stupid blogs all day. Wait a minute, I think I actually do that at work all day anyway. That means…..I AM ROBOT! I have trapped myself in my own vortex of truth.
    Oh no.

  6. I get the feeling these “life-like” creatures are made procedurally (via genetic algorithm, no doubt) by an AI that really has no idea what “life” looks like.
    Either that, or  it’s like in UHF when the blind man is trying to solve the Rubik’s cube:
    Is that it?
    How ’bout now?
