Abstrac t In this paper, we describe a fully autonomous, self-replicating, electromechanical circuit, and the minimalist manipulation system that the circuit uses as a substrate in order to function. In the contex t of a class proj ect at J HU, we designed and built a prototype system consisting of basic electronic components and motors which had the(More)
