A connection system for connecting a self-propelled guide unit to a self-propelled load bearing unit, wherein the self-propelled guide unit is configured to connect to and guide the self-propelled load bearing unit, such that the self-propelled load bearing unit can travel on a floor surface when the self-propelled guide unit and the self-propelled load bearing unit are connected;

• the connection system comprises:
• at least one engaging element, on the self-propelled load bearing unit,
• at least one engaging element, on the self-propelled guide unit,
• at least one actuator, on the self-propelled guide unit, configured to move the at least one engaging element on the self-propelled guide unit in a direction towards the floor surface for lifting the self-propelled guide unit, wherein:
• the at least one engaging element on the self-propelled guide unit is configured to engage the at least one engaging element on the self-propelled load bearing unit when the actuator moves the at least one engaging element on the self-propelled guide unit in a direction towards the floor surface, and wherein
• the at least one engaging element on the self-propelled load bearing unit carries a portion of the weight of the self-propelled guide unit, when the self-propelled guide unit is lifted from the floor surface.

A system for intralogistics comprising:

• at least one self-propelled load bearing unit;
• and
• a self-propelled guide unit configured to connect to and guide a self-propelled load bearing unit, such that the self-propelled load bearing unit can travel on a floor surface when the self-propelled guide unit and the self-propelled load bearing unit are connected, the self-propelled guide unit being configured to:
• receive at least one parameter from the self-propelled load bearing unit,
• use the at least one parameter in the generation of a control signal, and
• transmit the generated control signal to the self-propelled load bearing unit for controlling the propulsion of the self-propelled load bearing unit, the self-propelled guide unit comprises:
• at least one engaging element configured to engage at least one corresponding engaging element on the self-propelled load bearing unit, and
• an actuator configured to lift the self-propelled guide unit from the floor surface by moving the at least one engaging element on the self-propelled guide unit in a direction towards the floor surface, such that:
• the at least one engaging element on the self-propelled guide unit engages the at least one corresponding engaging element on the self-propelled load bearing unit, and
• the at least one engaging element on the self-propelled guide unit carries a portion of the weight of the self-propelled guide unit, when the self-propelled guide unit is lifted from the floor surface.
