An autonomous robotic fish
Less sexy than Aibo but still nifty, this autonomous robotic fisch seems interesting. Designed by Dan Massie, Mike Kirkland, Jen Manda, Ian Strimaitis
An autonomous, micro-controlled fish was designed and constructed using sonar to help guide it in swimming. It was predetermined that constructing a mechatronic fish would be a large and demanding project due to the complex shape of a fish body, the unfamiliar territories of sonar sensing, the intricacies of fluid propulsion, and the challenge of keeping submerged electronics dry. However, the team was willing to put in a lot of time and produced an exceptionally successful first prototype by the name of Dongle.
The most important part is about the design and construction of this robotic pet: using soft-clay, a tail servo, microcontrollers...
