FishPi: Raspberry Pi Powered Autonomous Boat To Cross the Ocean 136

Posted by Unknown Lamer from the dolphins-protest-sea-drone-program dept.
lukehopewell1 writes "The Raspberry Pi is a triumph in computing, and it's now set to become a triumph in robotics as one developer plans to build a model boat around it and sail it across the Atlantic Ocean, completely unmanned. It's codenamed FishPi and will see a model boat sail across the Atlantic all by itself save for a camera, GPS module, compass and solar panels." The creator is posting updates on the build progress using a forum on his website.

            The premise is that if you use robots you can spam them. Drugs are cheap where they are produced, some of them amazingly so. People are cheap too, but getting them to where you want them isn't necessarily. If you can build lots of small smuggling drones with toy technology and then spam your target with them, and have them receive-only until they are near their destination, there's no reason why they should be easily detected. The same is true, of course, of fleets of autonomous bombs.

We are on track to keep that commitment. We will have shipped out 41,000 Raspberry Pis by the end of May and our customers will have received, or will be receiving their Pis over the next few days. We are on track to have shipped 100,000 Raspberry Pis by the end of June and have further production planned for delivery to customers in July. (Modified on 20-June : We're sorry to have to say that due to an unforeseen production delay with our manufacturer, there will be a short delay of up to 1 week. Orders that were received before 18th April will now be shipped at the end of June / early July. For orders received after the 18th April, we will be shipping those deliveries throughout July into August. We will send you an email confirming your delivery prior to despatch.)
