Abstract
A sensor is configured to include an optical sensor including a light source and a plurality of light receivers which receive light emitted from the light source and light regularly reflected and diffusely reflected by an object, a database including output data regarding multiple objects of known and different types from the plurality of light receivers when an incident direction of light emitted from the light source forms a first direction to the object and when the incident direction of light emitted from the light source forms a second direction which is orthogonal to the first direction, and a processor which controls the light emitted from the light source to illuminate an object of unknown type and specifies the type of the object by matching the output data of the plurality of light receivers to the database.
