%A Gabriel Gomez %A Max Lungarella %A Peter Eggenberger Hotz %A Kojiro Matsushita %A Rolf Pfeifer %T Simulating development in a real robot: on the concurrent increase of sensory, motor, and neural complexity %X We present a quantitative investigation on the effects of a discrete developmental progression on the acquisition of a foveation behavior by a robotic hand-arm-eyes system. Development is simulated by (a) increasing the resolution of visual and tactile systems, (b) freezing and freeing mechanical degrees of freedom, and (c) adding neuronal units to the neural control architecture. Our experimental results show that a system starting with a low-resolution sensory system, a low precision motor system, and a low complexity neural structure, learns faster that a system which is more complex at the beginning. %K visual foveation, robotic hand, developmental progression, neural networks %P 119-122 %E Luc Berthouze %E Hideki Kozima %E Christopher G.
