I don’t what kind of circuit work we’re going to be doing in class, but I found this video to be pretty interesting. It’s a robotic fish engineered by scientists at Essex University in the UK. The fish is put in a special tank full of water and actually swims around very convincingly. All of its movement is controlled completely independently thanks to special sensors it possesses. The video didn’t mention what kind of internal programming the fish has, so I don’t have any idea what was used. It did remind me of some of the examples of PD & other similar programs we’ve seen that responded to stimuli via sensors (whether they were touch or merely motion of some sort). This video is also satisfying in that it shows the completed version of the fish with jeweled scales, as well as a stripped version that allows the viewer to see what kind of internal skeleton controls it.
