Abstract— In performing various kinds of tasks, body representation is one of the most fundamental issues for physical agents (humans, primates, and robots). Especially during tooluse by Japanese macaque monkeys, neurophysiological evidence shows that the representation can be dynamically reconstructed by spatio-temporal integration of different sensor modalities so that it can be adaptive to environmental changes [1]. However, to construct such a representation, an issue to be solved is how to associate which information among various sensory data. This paper presents a method that constructs cross-modal body representation from vision, touch, and proprioception. When the robot touches something, the activation of tactile sense triggers the construction process of the visual receptive ﬁeld for body parts that can be found by visual attention based on saliency map and consequently regarded as the end effector. Simultaneously, proprioceptive information is associated with this visua...
