A conceptual approach to material detection based on damping vibration-force signals via robot

open access: yesFrontiers in Neurorobotics
IntroductionObject perception, particularly material detection, is predominantly performed through texture recognition, which presents significant limitations. These methods are insufficient to distinguish between different materials with similar surface
