1. A method of transporting a sample container for analysis by a laboratory automation system, comprising:
- transporting a sample container containing a sample from an input area to a distribution area by a gripper comprising a means for inspecting a tube;
obtaining data during the transporting of the sample container, wherein the obtaining the data comprises,capturing an image of the sample container, analyzing the image to determine at least one physical characteristic of the sample container, and determining a sample container identification of the sample container based on the at least one physical characteristic,determining a liquid level of the sample in the sample container, andcalculating a weight of the sample container using the sample container identification and the liquid level;
requesting a sample schedule associated with the sample in the tube, wherein the sample schedule is requested from a scheduling system based on the data obtained during the transporting;
determining by the scheduling system a time when the tube containing the sample should be processed; and
transporting the tube from the distribution area to a subsequent processing module in the laboratory automation system at the time determined by the scheduling system.

Abstract
An analytical laboratory system and method for processing samples is disclosed. A sample container is transported from an input area to a distribution area by a gripper comprising a means for inspecting a tube. An image is captured of the sample container. The image is analyzed to determine a sample container identification. A liquid level of the sample in the sample container is determined. A scheduling system determines a priority for processing the sample container based on the sample container identification. The sample container is transported from the distribution area to a subsequent processing module by the gripper.
