Laboratory product transport element and path arrangement

A laboratory product transport element comprising

• an energy source to furnish drive power;
• at least one signal receiver to receive control signals from an external source and provide at least one control signal to a control unit;
• the control unit to generate drive signals as a function of the at least one control signal obtained from the at least one signal receiver;
• at least one movement device, with which the laboratory product transport element can move independently on a transfer path;
• at least one drive device to drive the at least one movement device as a function of the drive signals of the control unit, the at least one drive device being driven by the drive power;
• and
• at least one holder to hold a laboratory product to be transported;
• the laboratory product transport element further comprising one or more sensors configured to detect an indicator on a transfer path arrangement or receive a signal identifying a designated position on the transfer path arrangement;
• a housing that houses the control unit, wherein the housing comprises lateral protrusions that are cooperatively structured with rail elements which define a path for the laboratory product transport element, wherein each rail element comprises one or more slots configured to receive one of the lateral protrusion;
• and
• a memory unit coupled to the control unit, wherein the memory unit comprises code executable by the control unit to implement a method comprising:
• controlling the at least one drive device to cause the laboratory product transport element to rotate until at least one lateral protrusion couples with at least one slot.
