Laboratory sample distribution system

A laboratory sample distribution system, comprising:

• a number of sample container carriers;
• a number of transport modules, wherein each transport module comprises a transport surface, wherein the number of transport modules are arranged adjacent to one another in a row-direction and/or in a column-direction such that the transport surfaces of transport modules arranged adjacent to one another together form a common transport surface,
• each of the number of transport modules further comprises a controllable drive means arranged below the transport surface and adapted to move the sample container carriers on top of the common transport surface,
• at least some transport modules of the number of transport modules are movable transport modules adapted to be moved during operation of the laboratory sample distribution system such that:
• a gap is formed between transport modules arranged in the row-direction and/or the column-direction, and/or
• a gap is closed between transport modules arranged in the row-direction and/or the column-direction;
• and
• a proximity sensor sensing a user in proximity to the transport modules and in response initiating a movement of the movable transport modules and thereby forming the gap in the transport modules sufficient for the user to pass therethrough.
