Abstract: A display system includes a display and a controller. The controller causes the display to display a third figure representing a relative relationship between a first figure indicating a direction of a working implement of a working machine and a second figure indicating a direction of a target topography from the working machine.

Abstract: An attachment position determining method includes obtaining a first straight line connecting base and distal end portions a link member in a design phase, obtaining a flexure curve indicating a flexed state of the link member, obtaining a second straight line connecting the base end portion and the distal end portion on the flexure curve, obtaining a first angle formed between the first straight line and the second straight line, obtaining a second angle formed between the first straight line and a tangent line of the flexure curve, determining a position on the flexure curve as a reference position such that the second angle is equal to the first angle, and determining an attachment position of a postural detection sensor on the link member based on positional information in a lengthwise direction of the link member. The flexure curve is obtained based on the first straight line.

Abstract: A work machine capable of saving works by an operator during traveling is provided. The work machine includes a vehicular main body including a traveling unit, a work implement attached to the vehicular main body, and a controller that automatically controls operations by the work implement. The controller cancels automatic control of operations by the work implement based on a traveling state of the traveling unit.
