my robotic fish Very quick and dirty building (less then 20 hours) . A firs generation of robotic fish , with 3 RC servo that where water proof . A pic 16f877 mcu submerge in epoxy controlling every thing . There is a connection for 3 range sensors for obstacle dictation ,but they are not implemented in the code at this first ganaration. An water do find it’s why to every where!! look at my site : www.quickest-owl.com For detailed info about some of this projects in English translate.google.com

Robotic fish powered by tiny Gumstix computers (from cswww.essex.ac.uk )

Researchers at the University of Bath have used nature for inspiration in designing a new type of swimming robot which could bring a breakthrough in submersible technology. Conventional submarine robots are powered by propellers that are heavy, inefficient and can get tangled in weeds. In contrast Gymnobot, created by researchers from the Ocean Technologies Lab in the Universitys Department of Mechanical Engineering, is powered by a fin that runs the length of the underside of its rigid body; this undulates to make a wave in the water which propels the …

www.discoverynews.com A team of researchers at MIT are refining robotic fish technology, with the hope of using on reconnoissance missions, or for monitoring our waters.

Tail operation of my robotic fish, made as part of my mechatronics degree. There are four links in the tail, each powered by a servo motor. A microcontroller keeps them in time to form an artificial sine wave. Nylon string forms ‘tendons’.
