OUTDOOR PROCESSING SYSTEM

An outdoor treatment system has an autonomous mobile outdoor treatment robot and a sensor and control device. The outdoor treatment robot has a chassis and a contact element. The chassis is designed to execute a travelling movement of the outdoor treatment robot in a direction of travel. The contact element is designed to execute an avoiding movement in an avoiding direction as a result of the travelling movement in the direction of travel and contact between an obstacle and a lower contact point below a height limit and to execute a detection movement in a detection direction as a result of the travelling movement in the direction of travel and contact between an obstacle and an upper contact point at or above the height limit and is mounted so that it can move with respect to the chassis, wherein the avoiding direction and the detection direction are different. The sensor and control device is designed to detect the detection movement or a movement caused by the detection movement, and to control a protective function of the outdoor treatment robot triggered by the detected detection movement or the detected movement. The sensor and control device does not detect or evaluate the avoiding movement or a movement caused by the avoiding movement.
