Abstract

A robot and a working method by the robot is capable of favorably carrying out a specific work without requiring a jig for fixing an object, such as a workpiece etc., a device for adjusting the posture of the object, etc. One example of the robot includes a first robotic arm having at a tip end a hand part according to a specific work to be performed to an object, and a second robotic arm having at a tip end a hand part according to an assisting work to assist the specific work. The first robotic arm is configured to perform the specific work to the object. The second robotic arm is configured to perform the assisting work to regulate a movement of the object in a given direction, when the first robotic arm performs the specific work.

First claim

What is claimed is:

1 . A robot, comprising:
a first robotic arm having at a tip end a hand part according to a specific work to be performed to an object; and a second robotic arm having at a tip end a hand part according to an assisting work to assist the specific work, wherein the first robotic arm is configured to perform the specific work to the object, and wherein the second robotic arm is configured to perform the assisting work to regulate a movement of the object in a given direction, when the first robotic arm performs the specific work.

2 . The robot of claim 1 , wherein the second robotic arm is configured to perform, by pressing down the object placed on a given workbench, the assisting work to regulate an upward movement of the object and temporarily fix the object on the workbench.

3 . The robot of claim 2 , wherein the object is comprised of a plurality of laminated members, and
wherein the first robotic arm is configured to perform the specific work to fix the plurality of members with screws by tightening the screws to the object.

4 . The robot of claim 2 , wherein the first robotic arm is configured to perform the specific work to cut a given part of the object by cutting the object.

5 . The robot of claim 1 , wherein the second robotic arm is configured to perform, by performing an operation to guide the object being conveyed on a conveyor in a given direction of the width directions of the conveyor, the assisting work to regulate a movement of the object in a direction opposite to the given direction and make the object into a given posture with respect to the conveying direction, and
wherein the first robotic arm is configured to perform, by supplying a given thing to the object that became in the given posture, the specific work to store the given thing in the object on the conveyor.

6 . The robot of claim 1 , wherein the object is comprised of a box of which an upper surface is opened and in which one or more articles are accommodated,
wherein the second robotic arm is configured to perform, by performing an operation to put the article in the box aside in a given direction in a horizontal plane, the assisting work to regulate a movement of the article in a direction opposite to the given direction in the horizontal plane and secure a given space in the box, and wherein the first robotic arm is configured to perform, by supplying a given thing to a given position, the specific work to store the given thing in the space inside the box.

7 . The robot of claim 1 , wherein the object is comprised of a box of which an upper surface is opened and in which one or more articles are accommodated,
wherein the second robotic arm is configured to perform, by contacting a regulating member for preventing that the article in the box spread in a given direction in a horizontal plane with a side surface of the article, the assisting work to regulate a movement of the article in a direction opposite to the given direction in the horizontal plane and secure a given space in the box, and wherein the first robotic arm is configured to perform, by supplying a given thing to a given position, the specific work to store the given thing in the space inside the box.

8 . A working method by a robot, wherein the robot comprising a first robotic arm having at a tip end a hand part according to a specific work to be performed to an object and a second robotic arm having at a tip end a hand part according to an assisting work to assist the specific work performs the specific work to the object by an operation of the first robotic arm, and performs the assisting work to regulate a movement of the object in a given direction by an operation of the second robotic arm, when the specific work is performed.
