Bongard et al.<meta name="GENERATOR" content="OpenOffice.org 1.1.0 (Linux)" /><meta name="CREATED" content="20061228;18001700" /><meta name="CHANGED" content="16010101;0" /><br /> <style><!-- @page { size: 8.27in 11.69in; margin: 0.79in } P { margin-bottom: 0.08in } --></style> <p> describe a robot (left) that forms a representation of its own limbs that optimises locomotive behaviour. This in contrast with traditional robotic dichotomies, where an internal model is explicitly implemented by the designer, or where a reflexive controller is used (which typically requires training, forming an implicit model).<br /> This would be especially interesting approach in <a href="http://www2.parc.com/spl/projects/modrobots/">modular robots</a>, where numerous permutations of physical configuration are possible, but where the corresponding control algorithms aren’t neatly layed out.
