Document Type and Number:
WIPO Patent Application WO/2019/031502
Kind Code:
A1
Abstract:
A configuration in which a plurality of pressure sensors are positioned in each finger part of a hand mechanism, the configuration being capable of more accurately ascertaining the state of contact between a finger part and an object, the location on the finger part of contact with the object, and the like. A hand mechanism which is equipped with a plurality of finger parts and grips an object using the finger parts, wherein the outer surface of each finger part has a plurality of pressure sensors attached thereto, and two adjacent pressure sensors among the plurality of pressure sensors are positioned so as to adjoin one another. In addition, a flexible cover formed from a flexible film-shaped member for covering the plurality of pressure sensors is attached to each finger part. Such a configuration makes it possible to accurately detect contact between a finger part and an object even when the object contacts a dead zone formed between the sensor elements of two adjoining pressure sensors.
