And now for something completely different. Boris Landoni from Open Electronics has constructed and documented his robotic fish. With a body made from polystyrene, he modified it to have three vertical joints. Each joint contains a servo which in combination cam created the required movements to emulate a real fish. Sharp infra-red distance sensors have been added so the fish doesn't swim into objects, and the control is a simple matter of programming the Arduino compatible. The final results are successful - for example (turn volume down):
Add a laser to the head and it's perfect... Nevertheless, visit the project page for more details. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
Want to make your own Arduino-controlled project with servos and more - but not sure how to start? Then the best way to learn is with out new Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects!
