  • OPTICAL TACTILE SENSOR, ROBOT HAND, AND ROBOT ARM
    Publication number: 20250269540
    Abstract: An optical tactile sensor comprising a contact part having a contact surface that comes into contact with an object, the contact part being deformed in response to a contact state of the object with respect to the contact surface; a marker disposed on the contact part, and configured to be displaced in response to deformation of the contact part; and an imaging unit configured to capture an image of the marker from a side opposite to a side where the object comes into contact, wherein the contact part allows light in a first wavelength range to pass therethrough, and blocks light in a second wavelength range different from the first wavelength range, the marker reflects light that is incident on the marker from the opposite side, and the imaging unit receives the light reflected by the marker and the light in the first wavelength range, and generates an image.

  • Control of object operating force, object gripping force and robot hands
    Patent number: 7707001
    Abstract: An optical tactile sensor has a touch pad and a CCD camera for imaging behavior of the touch pad. A CPU processes image information from the CCD camera, extracts information on the size, shape, and center of gravity of a contact region, and extracts information on the size of a fixation region. The CPU obtains a normal force from the size of the contact region, obtains a tangential force from the shape of the contact region and the center of gravity of the contact region, and obtains a friction coefficient from the ratio of the size of the fixation region to the size of the contact region.
