  • Patent number: 12178153
    Abstract: An outdoor treatment system has an autonomous mobile outdoor treatment robot and a sensor and control device. The robot has a chassis and a contact element. The chassis executes a travelling movement in a direction of travel. The contact element executes an avoiding movement in an avoiding direction as a result of the travelling movement and contact between an obstacle and a lower contact point below a height limit, and executes a detection movement in a detection direction as a result of the travelling movement and contact between an obstacle and an upper contact point at or above the height limit. The contact element is mounted to move with respect to the chassis. The avoiding direction and the detection direction are different. The sensor and control device detects the detection movement and controls a robot protective function, and does not detect or evaluate the avoiding movement.
