The Verge reports on the Zipheus Aquatic Drone after seeing it at the Engadget event in San Francisco:
We played around with an early prototype in a kiddy-pool and it does exactly what you'd expect, cutely tootling around at a slow pace (they rightly didn't trust us with the full-speed version in such a tiny space). The Wi-Fi range will vary, of course, and the company expects that your average battery life should be about an hour — depending on just how hard you push the motors. Luckily, the Ziphius has a very low center-of-gravity, so it should be able to handle wake and waves and recover gracefully when flipped. Ziphius is an entrant in the "Insert Coin" competition at the Engadget Expand conferenceand hopes to launch on Kickstarter in a month or so, for "around $200."
