Camera-based tactile sensor

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.

Benefits

How does our solution help you?

Tactile Profile

Pressure profile, e.g. to be used as touch feedback for gripper fingers

Passive Element

No electronics/wiring

Remote Sensing

External camera (“eye-in-hand” on the gripper), or nearby

Virtual sensor

Tactile signal from image processing
