The obtained results demonstrate how the proposed methodology allows the robot to produce effective behaviours thanks to its ability to exploit the morphological properties of the robot’s body (i.e. its anthropomorphic shape, the elastic properties of its muscle-like actuators, and the compliance of its actuated joints) and the properties which arise from the physical interaction between the robot and the environment mediated by appropriate control rules. date: 2007-11 date_type: published publication: Frontiers in Neurorobotics volume: 1 number: 4 refereed: TRUE referencetext: Arbib, M.A., Billard, A., M., I., and E., O.
