Robot system and method for producing to-be-worked material

A method for manufacturing a to-be-worked material using a robot system, the robot system comprising:

• a first cell comprising:
• a first robot configured to perform a predetermined kind of work on the to-be-worked material within a first movable area;
• a first controller configured to control the first robot;
• and
• a first casing including a first bottom wall, first side walls, and a first top wall, a first accommodation space defined by the first bottom wall, the first side walls, and the first top wall accommodating the first robot and the first controller;
• and
• a second cell comprising:
• a second robot configured to perform a predetermined kind of work on the to-be-worked material within a second movable area;
• a second controller configured to control the second robot;
• and
• a second casing including a second bottom wall, second side walls, and a second top wall, a second accommodation space defined by the second bottom wall, the second side walls, and the second top wall accommodating the second robot and the second controller and being connectable to the first casing,
• the method comprising:
• detecting a contact between a first wall of the first side walls and a second wall of the second side walls;
• respectively controlling the first robot and the second robot to work in a common operation area using the first controller and the second controller when detecting the contact, the common operation area being where the first movable area and the second movable area overlap;
• conveying the to-be-worked material into a work area of at least one robot among the first robot and the second robot;
• controlling the at least one robot among the first robot and the second robot to perform the predetermined kind of work on the to-be-worked material;
• and
• after controlling the at least one robot among the first robot and the second robot to perform the predetermined kind of work on the to-be-worked material, taking out the to-be-worked material from the work area.
