Tactile sensors provide a pressure or contact profile, similar to touch we feel on our skin. They offer rich feedback about the grasping process and are thus essential for adaptive and sensitive grasping processes. Our camera-based solution requires only a passive and deformable material, which deforms on pressure. Our image processing software derives a tactile signal from the observed deformation.
Pressure profile, e.g. to be used as touch feedback for gripper fingers
External camera (“eye-in-hand” on the gripper), or nearby
Tactile signal from image processing
