Abstract: Disclosed are systems and methods for safely navigating an autonomous work vehicle by instructing the autonomous work vehicle to provide measured responses according to the proximity of an obstacle to the autonomous work vehicle. The response of the autonomous work vehicle may be determined based on a response set associated with one or more zones disposed around the autonomous work vehicle or about a selected navigational path. The response set may include warnings, such as activation of lights and/or alarms of the autonomous work vehicle, and/or motor actions, including reducing a velocity of the autonomous work vehicle, selecting another navigational path to avoid the obstacle, and/or adjusting the activation and/or position of an implement connected to the autonomous work vehicle. A response may be initiated when visual sensor signal data associated with a zone indicates the presence of an obstacle within the zone.
