Robot system and control method of robot system

A robot system configured to manipulate a character input device to perform a work operation for inputting specified character information written in a paper document, the character input device being located at a predetermined position, including a plurality of manipulation parts used to input a command of the specified character information, and being configured to send the input command of the specified character information to an information processing device, the robot system comprising:

• a manipulation tool unit capable of manipulating each of the plurality of manipulation parts of the character input device;
• a robot including a robot arm unit which is capable of holding the manipulation tool unit and is configured to move the manipulation tool unit in a state in which the manipulation tool unit is held by the robot arm unit;
• an imaging device;
• and
• a controller including:
• an imaging device control section which controls the imaging device to take an image of the paper document;
• a character string determiner section which determines a character string as an input target of the paper document which is contained in image data obtained by the imaging device;
• a manipulation part position determiner section which determines a position of the manipulation part corresponding to each character of the character string determined by the character string determiner section;
• and
• a robot control section which controls the robot arm unit so that the manipulation tool unit held by the robot arm unit moves while manipulating the manipulation part determined by the character string determiner section in an arrangement order of characters of the character string, based on the position of the manipulation part corresponding to each character of the character string, which is determined by the manipulation part position determiner section.
