3P2-P02 Tool-body Assimilation Model based on Body Babbling and a Neuro-dynamical System for Acquiring Representaion of Tool Function(Neurorobotics & Cognitive Robotics)

Abstract

We propose a tool-body assimilation model based on body babbling and a neuro-dynamical system for robots to use tools and acquire representaion of tool function. We took the following approach: We used a humanoid robot model to generate random motions based on human body babbling. These rich motion experiences were used to train recurrent and deep neural networks for modeling a body image. Tool features were self-organized in parametric bias, modulating the body image according to the tool in use. Finally, we designed a neural network for the robot to generate motion only from the target image. Experiments were conducted with multiple tools for manipulating a cylindrical target object. The results show that the tool-body assimilation model is capable of motion generation.
