Center node: "learning efficient haptic shape exploration with a rigid tactile sensor array"
  Abstract: Haptic exploration is a key skill for both robots and humans to discriminate and handle unknown or recognize familiar objects. Its active nature is impressively evident in humans which from early on reliably acquire sophisticated sensory-motor capabilites for active exploratory touch and directed manual exploration that associates surfaces and object properties with their spatial locations. In stark contrast, in robotics the relative lack of good real-world interaction models, along with very restricted sensors and a scarcity of suitable training data to leverage machine learning methods has so far rendered haptic exploration a largely underdeveloped skill for robots, very unlike vision where deep learning approaches and an abundance of available training data have triggered huge advances. #R##N#In the present work, we connect recent advances in recurrent models of visual attention (RAM) with previous insights about the organisation of human haptic search behavior, exploratory procedures and haptic glances for a novel learning architecture that learns a generative model of haptic exploration in a simplified three-dimensional environment. The proposed algorithm simultaneously optimizes main perception-action loop components: feature extraction, integration of features over time, and the control strategy, while continuously acquiring data online. The resulting method has been successfully tested with four different objects. It achieved results close to 100% while performing object contour exploration that has been optimized for its own sensor morphology.
