Robots are capable of doing many things for us, including doing lab work. Take COBOTTA by DENSO Robotics: as a part of the Futurelab, this robot arm can work knobs and handle samples. It has an auto-focus camera mounted on it that can recognize mixers and rotors. It can also be used to read barcodes and keys.
The robot weighs only 4kg and has a payload of 500g. Its shoe-/rail system makes it easier to use the robot in all kinds of workplaces. The above video shows this robot in action.
