Abstract:
1. A sensor comprising: 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, for each object type amongst multiple known and different types of objects, (i) output data from the plurality of light receivers when an incident direction of the light emitted from the light source on an object of the object type forms a first direction in relation to the object of the object type and (ii) output data from the plurality of light receivers when the incident direction of the light emitted from the light source on the object of the object type 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.
