Abstract
This application discloses a tactile sensor, a detection method for a touch event, a sensing device and a robot, and belongs to the field of sensor design. The tactile sensor includes: a sensing unit, an elastomer support housing and a base; the sensing unit is disposed in an inner cavity enclosed by the elastomer support housing and the base; and the sensing unit includes at least two light sources, a photo detector and a reflector, where the photo detector is disposed on base, the at least two light sources are disposed around the periphery of the photo detector on the base, and the reflector is disposed at the top of an inner cavity of the elastomer support housing. By adopting the combination of a plurality of light sources and one photo detector, the number of photo detectors for use is reduced, so that the volume of the tactile sensor is reduced.
