The autonomous travel working machine includes a working body unit, a cover unit, and a connecting structure unit connecting the working body unit and the cover unit. The connecting structure unit includes a body connecting section attached to the working body unit and a cover connecting section attached to the cover unit. When the cover unit is lifted, a shaft portion of the cover unit is slid upwardly with respect to a head portion of the working body unit so that the cover unit is moved upwardly or lifted with respect to the working body unit. When the working machine hits against an obstacle, an intermediate portion of the body connecting section is resiliently deformed in a lateral direction so that the cover unit is moved with respect to the working body unit substantially only in the lateral direction.

To provide a highly reliable, cost-effective traveling collector that can determine the positions of fallen objects, such as balls, on the ground using a simple method, or determine the correct positions of fallen objects, such as balls, on the ground only by improving software and without the need for significant changes to hardware. The traveling collector includes a count sensor as a sensor for detecting the position of each collected ball at a position detected by a satellite positioning system, for example. A controller determines a position, which is obtained by reflecting, based on the positional information on the ball collector at a time point when the ball was counted by touching the count sensor, the movement distance of the ball collector from the time each ball was picked up from the ground by a ball collection wheel till the ball was counted by touching the count sensor in a direction opposite to the traveling direction of the ball collector at that time, as the actual position where each ball was picked up.
