Embodiments of the present invention relates to a self-moving apparatus and a method for controlling same, the self-moving apparatus including: a housing; a movement module for driving the housing to move; an ultrasonic module configured to transmit an ultrasonic signal and receive an echo signal formed through reflection of an obstacle; and a control module installed on the housing and connected to the ultrasonic module, to implement an ultrasonic detection function by processing the echo signal, thereby controlling a movement mode of the movement module. The control module can control disabling of the ultrasonic detection function according to a received preset signal.

The disclosure relates to a portable work apparatus. The work apparatus includes a spacer which is arranged on the front housing and has a contact region. The contact region has a maximum distance, as measured radially, with respect to the rotational axis of the output shaft, the distance being greater than the cutting radius of the cutting tool in a first, non-deformed state of the spacer. The spacer is elastically deformable. The spacer is elastically deformed in a second state in such a manner that the maximum distance of the contact region is at most the same size as the cutting radius, and the spacer is arranged completely outside the cutting plane of the cutting tool.

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 riding type vehicle has a driving source, a left wheel and a right wheel, a transmission configured to receive power from the driving source to independently operate and drive the left wheel and the right wheel with regard to a rotation direction and a rotation speed, and caster wheels separately provided in a front-rear direction with respect to the left wheel and the right wheel, the riding type vehicle including two first sensors arranged on both left and right sides more to a front side than a rear end of the vehicle, the two first sensors configured to detect an obstacle target located on a rear side, the obstacle target being a target becoming an obstacle at the time of reversing or turning.

An autonomous lawn mower is described which is provided with boundary information of a region, explores the region, and based on information collected while exploring, is configured to mow the region in accordance with a mow pattern. Exploration may be performed based on random motions, striping, etc. Sensor data captured during exploration is captured in order to determine the presence of any objects within the region (e.g., trees, manmade objects, lakes, and the like). Sensor data and boundary information is used to optimize a mow pattern for the lawn mower to follow when mowing the region. Additional sensor data captured while mowing may be used for obstacle avoidance, monitoring of the system, or otherwise generating notifications.

A rotary vegetation cutting unit having: a frame having a drive shaft; at least one cutting element that moves with the frame; and a debris blocking assembly on the frame with a unitary part that moves relative to the frame in opposite directions around an operating axis. The unitary part is configured to deflect away from the at least one cutting element objects approaching the at least one cutting element in a radial direction. The rotary vegetation cutting unit further has a bearing assembly including: a) a bearing that guides movement between the unitary part and the shaft; and b) a holder for the bearing. The rotary vegetation cutting unit is configured so that any debris spaced radially from the rotary vegetation cutting unit is required to traverse a non-straight path to contact the bearing.

A work vehicle fleet includes a first model of work vehicle and a second model of work vehicle, different than the first model. The first model includes a first set of display devices; a first set of cameras; and a first controller configured to display a standard set of feeds from the associated first side, second side, and central location of the first set of cameras at the first set of display devices so that the associated feeds are arranged at the first side, the second side, and the central location, respectively, relative to the first operator FOV. The second model includes a second set of display devices; a second set of cameras; and a second controller configured to display so that the associated feeds are arranged at the first side, the second side, and the central location, respectively, relative to the second operator FOV.

In accordance with an example embodiment, an agricultural vehicle may include first and second harvesting devices connected to the agricultural vehicle. The agricultural vehicle may include a sensor which detects whether the agricultural vehicle is traveling in an operational or non-operational direction. The agricultural vehicle may include a lift controller in communication with the sensor and the first and second harvesting devices. The lift controller may automatically reposition the first and second harvesting devices into non-operating positions when the lift controller determines an intention to move the agricultural vehicle in a non-operational direction.

An automated system for moving a crop harvester relative to an obstacle in a crop field. The system includes a sensor that is configured to sense a presence of the obstacle in the crop field, and transmit a signal corresponding to the presence of the obstacle. A motor is configured to move the crop harvester relative to the agricultural vehicle. A controller is configured to activate the motor based upon the signal received from the sensor and thereby move the crop harvester relative to the agricultural vehicle to prevent physical contact between crop harvester and the obstacle.

An obstacle detection system for an agricultural work vehicle includes: an obstacle estimation unit 52 that estimates a region in a field based on a detection signal from an obstacle sensor 21 in which region an obstacle is present, and outputs obstacle present region information; an image capturing unit 22 that outputs a captured image of the field; an obstacle detection unit 54 that detects the obstacle from an input image and outputs obstacle detection information; and an image preprocessing unit 53 that generates, as an image to be input to the obstacle detection unit 54, a trimmed image obtained by trimming the captured image so as to include the region in which the obstacle is present, based on the obstacle present region information and shooting-angle-of-view information regarding the image capturing unit 22.
