A method of mowing multiple areas includes training a robotic mower to mow at least two areas separated by a space, including moving the robotic mower about the areas while storing data indicative of location of boundaries of each area relative to boundary markers, training the robotic mower to move across the space separating the areas, and initiating a mowing operation. Training the robotic mower to move across the space separating the areas includes moving the robotic mower to a traversal launch point of a first of the areas and moving the robotic mower to a traversal landing point of a second of the areas. The mowing operation causes the robotic mower to move to the traversal launch point, move from the traversal launch point across the space to the traversal landing point, and then mow the second of the areas.

A robotic lawn mower includes a first wheel driven by a first electric wheel motor, a second wheel driven by a second electric wheel motor, a cutting implement driven by an electric cutting implement motor, a power system for powering the electric wheel motors and the electric cutting implement motor, and a controller configured to control operation of the electric wheel motors and the electric cutting implement motor to autonomously mow a yard. The power system includes multiple removable rechargeable battery modules and multiple receptacles, each receptacle configured to receive one of the battery modules.

A lawn mower including a housing; a walking mechanism, supporting the housing and driving the housing to move, and including at least one drive wheel; at least one motor to drive the at least one drive wheel to rotate; and a control apparatus, preset with a first and a second torque threshold. And when the motor is switched from a stopped state to a running state, the control apparatus controls a difference between a maximum operating output torque of the motor and the first threshold to be within a predetermined range, when the motor is in the running state, the control apparatus controls an operating output torque of the at least one motor to at most increase to the second threshold, the first threshold is less than or equal to a maximum output torque of the motor, and the second threshold is less than the first threshold.

An autonomous mobile outdoor ground treatment robot includes an at least upper-side outer contour and a display screen device. The at least upper-side outer contour includes a contour face in a plan view of the outdoor ground treatment robot. The display screen device comprises a display screen face. The size of the display screen face in plan view of the outdoor ground treatment robot is at least 5% of a size of the contour face.

There is provided a mobile autonomous agricultural system comprising: a powered mobile unit for carrying agricultural equipment, and configured to move along rows of crops; at least one laser curtain sensor configured to project a laser curtain away from the mobile unit; a location module configured to monitor a location of the mobile unit relative to a row; a controller configured to control the travel of the mobile unit; a safety module configured to: receive a location signal from the location module related to the location of the mobile unit relative to a row, select a mode of operation to process the laser curtain in a predefined laser curtain pattern, based on the received location signal, each mode of operation corresponding to a different predefined laser curtain pattern, and to generate a safety output in response to determining that the laser curtain is interrupted within the laser curtain pattern.

A robotic lawn mower includes a mowing element, a body, a drive assembly, a first detection module, a second detection module, a failure determination module, an execution module, and a control module. The first detection module detects a first journey of the robotic lawn mower in a period. The second detection module detects a motion parameter of the drive assembly in the period and calculates a second journey of the robotic lawn mower in the period. The failure determination module determines whether a difference between the second journey and the first journey is greater than or equal to a first preset value. The execution module drives the robotic lawn mower to execute a response program. When the difference is greater than or equal to the first preset value in each of n1 consecutive periods, the control module controls the execution module to execute the response program.

A mower's control system can maintain horizon maps that associate horizon features with known relative positions. When a mower's orientation is unknown, the control system can obtain an image that captures the horizon from the mower's current viewpoint. The control system can process the image to detect any horizon features that appear within the image and to determine their positions within the image. The control system can then access a horizon map to identify matching horizon features. The control system can compare the known relative positions of any matching horizon features with the positions of the horizon features within the image to thereby determine the mower's current orientation.

A row unit for a header of an agricultural harvester. The row unit includes a frame, a first deck plate assembly mounted to the frame, and a second deck plate assembly mounted to the frame. The first and second deck plate assemblies each include a deck plate, a plurality of deck plate segments extending from the deck plate and moveable between a first position and a second position relative to the deck plate, and a plurality of biasing members for biasing each respective deck plate segment. The row unit includes both operator controlled macro adjustment and automatic micro adjustment of a gap between the first deck plate assembly and the second deck plate assembly. The micro adjustment is achieved through biasing members biasing each respective deck plate segment.

A radio-controlled vehicle includes a supporting structure, an engine unit, a kinetic unit and a remote control for operating the vehicle remotely, The radio-controlled vehicle also has a cab configured to house, in use, a person. The cab and the supporting structure are mutually movable with respect to each other to selectively arrange the cab in a desired position with respect to the supporting structure.

An aerial lawnmower, including a main body, a mower assembly disposed on at least a portion of a first end of the main body to cut at least one vegetation in response to rotating, and a plurality of rotors disposed on at least a portion of a second end of the main body to perform at least one of increase and decrease an elevation of the main body in response to rotating.
