A work machine includes a frame, a sensor assembly, and an ultrasonic sensor. The frame includes a first portion and a second portion that includes a front bumper and is configured to pivot with respect to the first portion for steering the work machine. The sensor assembly is positioned on the first portion or the second portion of the frame and is configured to sense data for detection of obstacles within a first area around the work machine. The ultrasonic sensor is positioned on the front bumper of the second portion and is configured to sense data for detection of obstacles within a second area around the work machine, the second area outside the first area when the second portion is in an articulated position with respect to the first portion.

A system and method for marking a boundary while defining an autonomous worksite includes receiving first information indicative of a first maneuvering distance from a side of a machine and activating an indicator. The indicator, representative of the first maneuvering distance, is positioned at the side of the machine to be visible to an operator of the machine. The machine is positioned on a worksite surface along a path to be traversed when executing a work plan. After a control system receives a verification from the operator that the machine may operate outside the worksite area and within an outer boundary defined by the first maneuvering distance, a worksite perimeter is defined to include the path, and a geofence for the machine is determined to substantially overlay the outer boundary.

A compactor machine can include a machine frame; at least one cylindrical roller drum rotatably coupled to the machine frame and rotatable about a drum axis oriented generally transverse to a direction of travel of the compactor machine; a plurality of cameras mounted to the machine frame so as to provide a 360° bird's eye view of an area around the machine; a display showing the 360° bird's eye view; and a controller; wherein, the controller is configured to determine certain conditions regarding a compacting operation of the compactor machine and the controller overlays a highlight symbol on the 360° bird's eye view on the display notifying a machine operator of the certain conditions.
