Abstract

A robot system includes a cell; and a first robot and a second robot which are provided in the cell, in which the first robot includes an n-th (n is an integer which is equal to or greater than 1) arm which rotates around an n-th rotating axis, and an (n+1)th arm which is provided to rotate around an (n+1)th rotating axis which is an axial direction different from an axial direction of the n-th rotating axis, in the n-th arm, in which the length of the n-th arm is longer than the length of the (n+1)th arm, and in which, when viewed from the (n+1)th rotating axis, the n-th arm and the (n+1)th arm overlap each other.

First claim

What is claimed is:

1 . A robot system comprising:
a cell; and a first robot and a second robot which are provided in the cell, wherein the first robot includes an n-th (n is an integer which is equal to or greater than 1) arm which rotates around an n-th rotating axis, and an (n+1)th arm which is provided to rotate around an (n+1)th rotating axis which is an axial direction different from an axial direction of the n-th rotating axis, in the n-th arm, wherein the length of the n-th arm is longer than the length of the (n+1)th arm, and wherein, when viewed from the axial direction of the (n+1)th rotating axis, the n-th arm and the (n+1)th arm overlap each other.

2 . The robot system according to claim 1 ,
wherein the first robot includes a first base provided in the cell, and wherein the n-th arm is provided on the first base.

3 . The robot system according to claim 1 ,
wherein the second robot includes a second base, an m-th (m is an integer which is equal to or greater than 1) arm which is provided on the second base and rotates around an m-th rotating axis, and an (m+1)th arm which is provided to rotate around an (m+1)th rotating axis which is an axial direction parallel to an axial direction of the m-th rotating axis in the m-th arm.

4 . The robot system according to claim 1 ,
wherein the second robot includes an m-th (m is an integer which is equal to or greater than 1) arm which rotates around an m-th rotating axis, and an (m+1)th arm which is provided to rotate around an (m+1)th rotating axis which is an axial direction different from an axial direction of the m-th rotating axis in the m-th arm.

5 . The robot system according to claim 4 ,
wherein the length of the m-th arm is longer than the length of the (m+1)th arm, and wherein, when viewed from the axial direction of the (m+1)th rotating axis, the m-th arm and the (m+1)th arm overlap each other.

6 . The robot system according to claim 4 ,
wherein the second robot includes a second base provided in the cell, and wherein the m-th arm is provided on the second base.

7 . The robot system according to claim 1 ,
wherein the cell includes a first surface, and a second surface which opposes the first surface, wherein the first robot is provided on the first surface, and wherein the second robot is provided on the second surface.

8 . The robot system according to claim 7 ,
wherein at least a part of the first surface overlaps at least a part of the second surface when viewed from the vertical direction.

9 . The robot system according to claim 1 ,
wherein the first robot includes a first base provided in the cell, wherein the n-th arm is provided on the first base, wherein the second robot includes a second base provided in the cell, and an m-th arm provided on the second base, and wherein at least a part of the first base overlaps at least a part of the second base when viewed from the vertical direction.

10 . The robot system according to claim 1 ,
wherein an installation area of the cell is less than 637,500 mm 2 .

11 . The robot system according to claim 1 ,
wherein an installation area of the cell is less than 500,000 mm 2 .
