摘要： The present disclosure provides a method and a device for determining a motion parameter of an autonomous mobile device. The method includes: an anti-fall sensor detects a current chassis-floor distance between a chassis of the autonomous mobile device and a current floor, and transmits the current chassis-floor distance to a processor; the processor determines a correction coefficient corresponding to the current chassis-floor distance; the processor obtains an output of an optic flow sensor; the processor determines the motion parameter corresponding to the current chassis-floor distance based on a correction coefficient, a calibration coefficient, and the output of the optic flow sensor, which increases the accuracy of the motion parameter obtained through computation.

摘要： One variation of a method for autonomously delivering supplies to operators within a facility includes, accessing an instructional block defining: a location within the facility; and a target offset distance between an autonomous cart and an operator proximal the location. The method also includes: maneuvering the autonomous cart carrying a set of materials to a position within the facility proximal the location; and accessing a video feed from an optical sensor coupled to the autonomous cart. The method further includes: extracting a set of features from the video feed; interpreting a set of objects depicted in the video feed based on the set of features; and calculating an offset distance between a first object in the video feed and the autonomous cart. The method also includes, in response to the offset distance deviating from the target offset distance, maneuvering the autonomous cart to the target offset distance.

摘要： A robot includes an image sensor that captures the environment of a storage site. The robot visually recognizes regularly shaped structures to navigate through the storage site using various object detection and image segmentation techniques. In response to receiving a target location in the storage site, the robot moves to the target location along a path. The robot receives the images as the robot moves along the path. The robot analyzes the images captured by the image sensor to determine the current location of the robot in the path by tracking a number of regularly shaped structures in the storage site passed by the robot. The regularly shaped structures may be racks, horizontal bars of the racks, and vertical bars of the racks. The robot can identify the target location by counting the number of rows and columns that the robot has passed.

摘要： An autonomous mobile device (AMD) builds up electrostatic charges from moving and generates heat from the operation of internal components. In addition to possible user discomfort, electrostatic discharges may damage sensors and electronics. Electrostatic charges are dissipated from the AMD using an electrostatic dissipation structure and conductive wheels. A conductive path between a chassis ground, the electrostatic dissipation structure, and the conductive wheels improves the dissipation of electrostatic charges. Electrostatic charges are also dissipated from components by mounting the components using conductive materials. Sensors may be affixed to a support structure that is affected by thermal expansion. Thermal expansion may distort precise positioning of sensors, reducing accuracy of sensor data. An elastomeric foam may be used to mount sensors to a support structure, allowing for thermal expansion without distorting the positioning of the sensors.

摘要： Systems and methods use cameras to provide autonomous navigation features. In one implementation, a method for navigating a user vehicle may include acquiring, using at least one image capture device, a plurality of images of an area in a vicinity of the user vehicle; determining from the plurality of images a first lane constraint on a first side of the user vehicle and a second lane constraint on a second side of the user vehicle opposite to the first side of the user vehicle; enabling the user vehicle to pass a target vehicle if the target vehicle is determined to be in a lane different from the lane in which the user vehicle is traveling; and causing the user vehicle to abort the pass before completion of the pass, if the target vehicle is determined to be entering the lane in which the user vehicle is traveling.
