Methods and apparatus are disclosed for automatic sensitivity adjustment for an autonomous mower. An exemplary mower includes a drive system and one or more cameras. One or more processors are configured to generate a grass value by applying an image recognition algorithm to one or more images, instruct the drive system to autonomously adjust a velocity of current movement in response to determining that the grass value is less than or equal to a mowing threshold, determine a trigger rate that indicates how often the grass value is less than or equal to the mowing threshold within a predefined period of time, decrease the mowing threshold by a decrement in response to determining that the trigger rate is greater than an upper threshold rate, and increase the mowing threshold by an increment in response to determining that the trigger rate is less than a lower threshold rate.

A robotic work tool comprising a motor for driving at least one wheel, an inclination sensor and a controller for controlling the operation of the robotic work tool, the controller being configured to; receive a signal indicating a collision; determine if the signal indicating a collision is above a collision threshold level and, if so, determine that a collision has been detected, the robotic work tool being characterized in that the controller is further configured to: receive an indication of an inclination; and to adapt the collision threshold accordingly based on said indication of an inclination.

A drive-by-wire system can include pair of inputs and a controller configured to process signals from the inputs in a first mode and process the same signals differently in a second mode. The controller can be configured to, in the first mode, drive a first motor at a speed and direction that corresponds to the position of the first input and drive a second motor at a speed and direction that corresponds to the position of the second input and, in the second mode, drive the first motor and the second motor in the same direction and at the same speed using the first drive signal when the controller receives a second neutral signal from the second input, and drive the first motor and the second motor at different speeds and/or directions when the controller receives the first drive signal and the second drive signal.

Disclosed are a method and apparatus for avoiding collisions with obstacles by a first vehicle using sensors on an accompanying second vehicle. The second vehicle navigates proximate the first vehicle while aiming an obstacle detection sensor at a path of the first vehicle to detect objects in the path of the first vehicle. The locations of the objects are determined and transmitted to the first vehicle.

The present disclosure provides a traversal method and system, a robot and a readable storage medium. The method comprises: driving a robot to travel in a working region according to a predetermined mode and work synchronously; and adjusting the robot to continue working according to a predetermined first rule every time a turn sign is encountered, and adjusting the robot to return to the predetermined mode after the first rule is completed; wherein the first rule is: starting from the position where the turn sign is encountered, rotating clockwise or counterclockwise; after first rotation is carried out according to a first angle, continuing running for a first time according to the predetermined mode; and then, after second rotation is carried out according to a second angle in the same rotation direction as the previous rotation, continuing running for a second time according to the predetermined mode, the first angle being different from the second angle. The present disclosure is beneficial to improving the traversal ability and traversal efficiency of the robot.

Mowers are provided with a safety system to prevent obstacles, such as animals, located in the field from being hit by cutters of the mower. The safety system includes a control unit and at least one detector to detect the obstacle and then provide a warning signal to the control unit, when the obstacle is detected. The control unit provides a separation signal to at least one safety device in response to receiving the warning signal, and the at least one safety device causes separation between the obstacle and the at least one cutter in response to receiving the separation signal. The safety device may be at least one shield which is movable between a retracted position and a protecting position in which it extends in front of the at least one cutter to prevent contact between the at least one cutter and the obstacle.

A controller on a harvester vehicle is arranged to automatically identify a header in electrical communication with the vehicle upon key activation of the harvester vehicle. Programming instructions on the controller can generate notifications to the user based upon a state of activation of the float mechanism and the state of header identity detection. The controller also prompts the user to confirm the identity of the header if the detected identity of the header has changed. The controller also uses header identity to log usage hours of the header on the computer controller in association with the identity of the header such that maintenance schedules for a plurality of different headers interchangeably used on a common harvester vehicle can be tracked.

The present invention relates to a non-contact obstacle-avoiding autonomous lawn mower, including a housing, a moving module, a drive module, and a control module. An ultrasonic sensor assembly is disposed on the housing. The ultrasonic sensor assembly includes at least two ultrasonic sensors, including a first ultrasonic sensor and a second ultrasonic sensor. When a distance between an obstacle detected by the ultrasonic sensor assembly and the autonomous lawn mower is less than a preset distance, the control module controls the autonomous lawn mower to execute a preset obstacle-avoidance measure. Compared with the prior art, the present invention uses an ultrasonic sensor to detect an obstacle and sets a preset distance to prevent the autonomous lawn mower from colliding with the obstacle, thereby implementing non-contact obstacle avoidance of the autonomous lawn mower.

A mower path assistance system to encircle an obstacle projecting from a ground surface, including a barrier mat formed with a barrier mat aperture enclosed by the barrier mat and having a barrier mat aperture diameter, a perimeter edge, and a barrier mat installation slit extending from the perimeter edge to the barrier mat aperture, wherein the barrier mat is deformable around the barrier mat installation slit to create a pathway having a pathway width through which the obstacle may pass from the perimeter to the barrier mat aperture. The barrier mat has a plurality of edges with axes that intersect at obtuse angles.

A work vehicle includes a chassis, and a work implement movably coupled to the chassis and configured to perform a field-engaging function. The work machine also includes an actuator coupled to the work implement and configured to adjust a position of the work implement relative to a ground surface. The work machine further includes a controller in communication with an output device and a communication module. The controller is configured to monitor a location of the work machine via the communication module. The controller is also configured to load a field map from a field map database, the field map identifying at least one impact event comprising a geotagged location. The controller is further configured to display an alert via the output device in response to the location of the work machine approaching within a predetermined distance from the geotagged location.
