SENSOR AND METHOD FOR MEASURING TACTILE INFORMATION

摘要

The present invention relates to a sensor for measuring contact information, which comprises: a sensor unit which is divided into a first sensing surface with a spherical surface, and a second sensing surface with an aspherical surface; a measuring unit which measures force or torque applied to the sensor unit by an object; and a position calculating unit which assumes the surface of the sensor unit as either a spherical surface or an aspherical surface, in order to calculate a contact position between the object and the sensor unit from information measured by the measuring unit. Therefore, the provided sensor for measuring contact information can measure the strength of contact force and the position of a contact point at high reliability, applied to a complex structure type sensor where structures with various shapes are combined.
