Animat is a term that has become popular recently to describe artificial animals, whether genetically engineered, created virtually in artificial life simulators, or realized artificially as robots. Steve Potter of Georgia Tech's Neuroengineer Lab is creating animat cyborgs - part robot, part biological. He calls his creations Hybrots (hybrid robots). For a controller, he uses cultured neurocoritcal material from rats. The living neural network is connected via a two-way electrode array with a khepera mobile robot. Sensor input goes into the neural net which, in turn, learns to move around. For more, see Steve's Learning in Vitro webpage or a yesterday's Georgia Tech press release about Hybrots.
