1. A pipette robot, comprising:
a frame;
a deck operatively connected to the frame;
a gantry operatively connected to the frame;
a pipette operatively connected to the gantry, wherein said pipette comprises a pipette body;
a single motor operatively connected to the pipette body;
a plunger operatively connected to the single motor;
an ejector operatively connected to the pipette body; and
a computer operatively connected to the single motor, wherein said computer comprises:
at least one processor; and
a memory including instructions,
wherein the pipette does not include a second motor,
wherein the instructions, when executed by the at least one processor of the computer, cause:
moving, using the single motor, the plunger through a first range of motion, wherein the pipette robot performs one or more of aspirating liquids and dispensing liquids; and
moving, using the single motor, the plunger through a second range of motion,
wherein said movement of the plunger through the second range of motion contacts the plunger with the ejector, and
wherein said movement of the plunger through the second range of motion pushes the plunger against the ejector, causing a pipette tip connected to the pipette body to be ejected.
