Dispensing robot, method of controlling dispensing robot, and dispensing method

A method of controlling a dispensing robot of an assay robot system that includes a first contact surface oriented in a downward direction or an obliquely downward direction in a vertical direction and that dispenses when the dispensing robot operates a pipette that allows a tip to be attached to a lower end of the pipette and the attached tip to be detached by pressing a tip ejector, the dispensing robot including

• a robot arm that includes a hand to hold a pipette holding piece attached to the pipette;
• and
• a controller that controls operation of the robot arm, wherein
• the method of controlling a dispensing robot comprises:
• causing the controller to control the robot arm such that the robot arm holds the pipette with the tip attached thereto by causing the hand to hold the pipette holding piece and that the robot arm is elevated and the tip ejector is pressed by bringing an upper end portion of the tip ejector of the held pipette into contact with the first contact surface from the downward direction.

A dispensing method comprising:

• holding a pipette holding piece attached to a pipette with a hand of a robot arm;
• attaching a tip to the pipette by moving the pipette so as to insert the pipette to the tip;
• dispensing liquid using the pipette to which the tip is attached;
• and
• detaching the tip used for dispensing the liquid from the pipette by moving the pipette to as to bring a tip ejector of the held pipette into contact with a contact member.
