Look, we never claimed to be fish-ologists or anything like that, but we really don't have the foggiest idea of how this thing works. Sure, it has rechargeable batteries for up to 24 hours of swimming, and ultrasound for object avoidance, and even a cool robotic-fish
sounding name: "POPO." We're just totally in the dark as to where the propulsion system is on this thing, or what portions of the bot we're supposed to hug and kiss in moments of weakness when the cute-itude sweeps over us. Apparently this is a second-gen fish bot from the ITRI Creative Laboratory's Aqua project, but words of legitimacy like that won't saw us until we've seen some solid video and / or action shots.
