1. An autonomous navigating system with obstacle recognition comprising:

  • a sensor having a contact element prestressed in a direction of movement and movable against a prestressed force and a detector measuring a change in position of the contact element, and providing a sensor signal depending on said change in position, an evaluating device connected with the sensor, which provides a first obstacle signal representing an obstacle that cannot be moved by the system, when the sensor signal is greater or equal to a limit value (UG), and which provides a second obstacle signal representing an obstacle that can be moved by the system, when the sensor signal is lower than the limit value (UG), wherein the system stops in response to a first obstacle signal or moves around the obstacle and, upon a second obstacle signal, has an additional option to move on and thereby displace the obstacle.
