    Abstract: A working machine includes a machine body capable of traveling, a position detector to detect a position of the machine body, and a controller to control the machine body based on the position of the machine body detected by the position detector and a planned travel route. The planned travel route includes a straight section on which the machine body travels straight, and the controller includes a threshold setter to set a threshold according to work, and causes the machine body to perform a recovery movement to make a deviation between the position of the machine body detected by the position detector and the planned travel route less than the threshold when the machine body is at a start point of the straight section or is about to enter the start point of the straight section.

    Abstract: A paving machine can include a frame; a screed coupled to the frame; and the screed including a main screed plate and an extender screed plate, each of the main screed plate and the extender screed plate having an angle sensor associated therewith, the angle sensor for each of the main screed plate and the extender screed plate being positioned and configured to determine a paving angle of the main screed plate and the extender screed plate; and a controller, the controller configured to receive the paving angles of the main screed plate and the extender screed plate from the angle sensors and to change the paving angle of the main screed plate and the paving angle of the extender screed plate independently of each other.

    Abstract: An apparatus includes a video capture device and a processor. The video capture device may be mounted at a low position. The video capture device may be configured to generate a plurality of video frames that capture a field of view upward from the low position. The processor may be configured to perform video operations to generate dewarped frames from the video frames and detect objects in the dewarped frames, extract data about the objects based on characteristics of the objects determined using said video operations, perform path planning in response the extracted data and generate a video stream based on the dewarped frames. The video operations may generate the dewarped frames to correct a distortion effect caused by capturing the video frames from the low position. The path planning may be used to move the apparatus to a new location. The apparatus may be capable of autonomous movement.

    Abstract: Described herein are systems and methods for operating a mobile robot in an environment according to a coverage path generated using an environment map. The path includes a set of linear path segments connected by a number of turns therebetween, and the path minimizes or reduces the number of turns that the robot makes as it traverses the environment. An exemplary system includes at least one controller that partitions the environment map into regions with respective orientations based on the region's dimensional information and neighboring regions' properties, decomposes the regions into parallel ranks, and generates a coverage path using the ranks. One or more mobile robots can accomplish designated missions such as cleaning in the environment when moving along their respectively identified path.
