A motorized shopping trolley has a frame and two wheels which are driven by a drivetrain. A handle for pulling and/or pushing the trolley is provided with a force sensor which detects a force acting on the handle when being pulled or pushed. An inclination sensor detects a slope of the traveling surface and generates a slope signal. A load sensor detects a load weight of the trolley and generates a load signal. A step-detection sensor detects a step in a path of the trolley and generates a corresponding signal. A controller receives all pertinent signal from the sensors and generates a control signal for actuating the drivetrain such that the drivetrain produces a driving force corresponding to the force applied to the handle by a user.
