Industrial robot

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.

Robot hand

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.

Robot hand and robot

Fingers for holding a target project from shift members, and shift in accordance with the movement of the shift members shifted in predetermined axial directions by a shift mechanism to hold the target. Sliding members for shifting the shift members in the predetermined axial directions project from the shift members, and guide the shift members by sliding. According to this structure, a robot hand becomes smaller in size by decreasing the clearances between the fingers (moving the shift members closer to each other). Thus, the robot hand can hold a small target object within a small work space even though the robot hand conducts a parallel shift of the fingers.
