Figure 7. The principle of robotic object properties recognition: (A) robotic hand with tactile sensors to grasp object; (B) detect object external local properties including surface texture, stiffness, thermal conductivity, and chemical substance; (C) detect object global properties such as weight, position of centroid, shape, and pose; (D) detect object internal properties.
