If you don't know a gill from a dorsal fin, don't worry: this robot, developed by Harry Westavik's team at SINTEF Fisheries and Agriculture in Trondheim, Norway, uses 3D laser scanning to fillet your fish with precision.

Using a heap of algorithms, the robot can work out the best place to cut the fish, even distinguishing species and bearing in mind their particular foibles. It can even calculate volume—and hence approximate mass—to ensure that serving sizes are as close to equal as possible. It's hoped that a fully-automated salmon processing line will be up and running, using this technology, by 2016. So long, fishmongers. [New Scientist]
