The octor project is trying to build mechanical tentacles along the lines of octopus arms, elephant trunks and tongues. These sorts of things are powered by muscular hydrostats. As such the model is composed of a trio of liquid filled cylinders and cables rather than joints as in a more "traditional" robot.
