Abstract: A gripping device for handling sample containers is presented. The sample containers are closed by caps of a given cap type or are not closed by caps. The gripping device comprises a number of fingers configured to collectively cause gripping of a sample container, a tactile sensor device arranged at at least one of the fingers and configured to sample a longitudinal profile of the sample container and of the cap, if any, being gripped, and a control device coupled to the tactile sensor device. The control device determines if the sample container is closed by a cap or not closed by a cap based on the sampled longitudinal profile.

Abstract: A method for determining a vertical position of a horizontally extending interface between first and second components is presented. The first and second components are contained in a laboratory sample container in layers vertically separated from each other. The method comprises generating first data, generating second data in the form of picture data of the laboratory sample container containing the first and second components, determining a first probability distribution function in response to the first data, determining a second probability distribution function in response to the second data, and determining the vertical position of the horizontally extending interface depending on the first and second probability distribution functions. The first data depend on the vertical position of the horizontally extending interface. The first and second probability distribution functions assign a probability of the presence of the horizontally extending interface to a vertical position.

Abstract: A method for operating a laboratory automation system, the laboratory automation system comprising a carrier comprising a reception place for receiving a sample container configured to contain a sample to be analyzed by a laboratory device; a placement device configured to pick and place the sample container; an imaging device; and a data processing device comprising at least one processor and a memory. The method comprises detecting an image of the reception place; determining whether the reception place is free for receiving the sample container and the reception place is configured to receive the sample container, by applying a machine learning algorithm for image analysis of the image of the reception place; and placing the sample container in the reception place by the placement device if the reception place is determined as free and configured to receive the sample container. Further, a laboratory automation system is disclosed.
