20120175903 | ROBOT HAND - A robot hand that changes a space between finger members provided apart from each other includes: moving members on which the finger members are vertically provided; a palm member including a moving mechanism for moving the moving members in a predetermined axial direction; and guide members that guide the movement of the moving members in the predetermined axial direction. | 07-12-2012 |
20120175904 | ROBOT HAND - An aspect of the invention provides a robot hand that performs an action for gripping an object between plural finger sections provided to be capable of changing a distance between the finger sections. Between the plural finger sections, a palm section movable along a direction in which a base side of the plural finger sections and a distal end side of the plural finger sections are connected is provided. | 07-12-2012 |
20120286535 | ROBOT HAND AND ROBOT - A robot hand includes a palm section provided between a plurality of finger sections. The palm section may be brought into contact with an object while the object is gripped by the finger sections. The robot hand also includes a contact member that is detachably mounted on the palm section. The contact member may be brought into contact with the object instead of the palm section. Accordingly, even if an object is too small to be contacted by the palm section, it is possible to stably grip the small object since the contact member can be brought into contact with the object gripped by the finger sections instead of the palm section. | 11-15-2012 |
20120286536 | ROBOT HAND AND ROBOT - Four fingers forming a first finger pair and a second finger pair are driven in such a way that the four fingers move closer to or away from an object simultaneously at the same speed to grip the object. This eliminates the need to drive the fingers independently, which makes it possible to simplify the structure and control of the robot hand. Moreover, one of the two fingers forming the second finger pair is a deformable finger. Therefore, even when the second finger pair grasps the object before the first finger pair grasps the object, the deformable finger is deformed, and eventually it is possible to grasp the object with the four fingers. This allows the robot hand to grip various objects even though the robot hand has a simple structure and is controlled with ease. | 11-15-2012 |
20120290133 | ROBOT HAND AND ROBOT - A robot hand has a plurality of fingers including a contact sensing finger that senses contact with an object. A base provided with the fingers detects a resultant reaction force that is the combination of reaction forces from the fingers. When no resultant reaction force is detected, the plurality of fingers are moved toward the object, and when the contact sensing finger comes into contact with the object, a force that drives the fingers is switched to a force corresponding to a grasp force. When the contact sensing finger has not come into contact with the object but a resultant reaction force is detected, the driving of the fingers is terminated and the position of the base is corrected by moving the base in a direction in which the resultant reaction force having acted thereon is not detected any more. | 11-15-2012 |
20130181466 | ROBOT HAND - An aspect of the invention provides a robot hand that performs an action for gripping an object between plural finger sections provided to be capable of changing a distance between the finger sections. Between the plural finger sections, a palm section movable along a direction in which a base side of the plural finger sections and a distal end side of the plural finger sections are connected is provided. | 07-18-2013 |
