Abstract
A liquid handling robot has a worktable that supports a rack holding a set of pipette tips. The liquid handling robot also has an arm that is operably suspended above the worktable, where the arm includes a tip receiver that is configured to engage the set of pipette tips. A controller of the liquid handling robot is configured to raise the tip receiver away from the worktable to withdraw the engaged set of pipette tips from the rack. A sensor is fixed relative to the worktable and is operable to emit a beam. A microcontroller monitors the sensor with the arm in a checking position to determine if the rack interrupts in the beam to indicate that the rack stuck to the pipette tips, which is autonomously resolved by the liquid handling robot performing a corrective action.
