A map generation device that generates a route. The map generation device includes: a node detector that detects a node; a node information obtainer that obtains detected node information including location information of the detected node and path information indicating a positional relationship between the detected node and a path connected to the detected node; a node determiner that determines whether the detected node information matches previously-reached node information; a node information adder that adds, to the route map, the detected node information as new previously-reached node information when the node determiner determines a mismatch; and a map corrector that, when the node determiner determines a match, determines that the detected node corresponding to the detected node information and a node corresponding to the previously-reached node information are a same node and corrects the route map.

The present disclosure provides an autonomous inspection method of an inspection device, including: acquiring a location information of the inspection device; detecting whether an object to be inspected exists in the inspection region or not; pre-determining an orientation of the object to be inspected relative to the inspection device based on the location information of the inspection device, in response to the object to be inspected existing in the inspection region; moving the inspection device in a first direction according to the pre-determined orientation, and determining whether the object to be inspected exists in a second direction or not, where the second direction is the same as an extension direction of the scanning channel; and moving the inspection device in the second direction and inspecting the object to be inspected, in response to the object to be inspected being detected in the second direction.

An arithmetic device configured to perform an arithmetic process on a travel route for each of a plurality of work machines capable of conducting a work in a work region, the device comprising an acquisition unit for acquiring map information of the work region, and a setting unit for setting, for each work machine, a work start point, a work end point, and at least one intermediate point on an outer edge portion of the work region, and for setting, on the map information, the travel route from the work start point to the work end point to pass through the at least one intermediate point, wherein the travel route has a predetermined width, and a plurality of travel routes respectively corresponding to the plurality of work machines enclose the work region with the predetermined width.

A topometric map that enables autonomous navigation of an inventory robot. The topometric map is generated using the layout of a storage site and is made up of vertices and edges. The vertices are generated at pallet locations and other structural locations, and edges are generated between neighboring vertices. Vertices and edges have associated metrics that aid in the routing of the robot. The metrics of the vertices and edges may be updated as the robot navigates through the storage site by using a perception engine and state estimator. The metrics of the edges can be used to calculate an energy cost. The robot determines a shortest path between a source and destination vertex based on the energy cost associated with each edge.

A system includes a first vehicle and a second vehicle coupled with each other, the first vehicle and second vehicle configured to support a load. The system also includes one or more memory devices storing instructions thereon, that, when executed by one or more processors, cause the one or more processors to obtain one or more locations in a floorplan of a production system. The instructions also cause the one or more processors to obtain a route for the first vehicle and the second vehicle, from a first current position of the first vehicle and a second current position of the second vehicle to the one or more locations and generate a series of coordinated motions between the first vehicle and the second vehicle based on the route.

A vehicle coupling system includes a first vehicle, a second vehicle, and a tow bar. The first vehicle includes a drive motor configured to propel the first vehicle and a lifting implement configured to support a product for movement. The second vehicle includes a lifting implement configured to support the product for movement. The tow bar is coupled to the first vehicle at a first end of the tow bar and coupled to the second vehicle at a second end of the tow bar opposite the first end. Responsive to the drive motor propelling the first vehicle, the tow bar exerts a force on the second vehicle to maintain a space between the second vehicle and the first vehicle.

A vehicle includes a chassis, a frame, a tractive element, a drive motor, and a cart interface. The cart interface includes a base frame coupled to the frame assembly of the vehicle, and a first and second pin assembly. The first and second pin assembly each include first pin configured to engage a cart and a actuator configured to raise the pin relative to the frame. The first pin assembly also includes a first linear actuator configured to bias the first pin relative to the first linear actuator and to permit relative movement between the first pin and first linear actuator. The cart interface includes a first actuator to reposition the first pin independently of the second pin and is configured to hold the pin in either of a lowered position, a raised position above a lowered position and an intermediate position between the raised and lowered positions.

A vehicle includes a frame, a drivetrain coupled to the frame, a base assembly coupled to the frame, and a lifting implement coupled to and supported on the base assembly. The lifting implement includes a platform, a cradle rotatably coupled to and supported on the platform so that the cradle, a scissor assembly coupled between the platform and the base assembly, and a lift actuator coupled between the base assembly and the scissor assembly. The lift actuator is configured to selectively raise the cradle relative to the base assembly. The lift actuator is a multi-stage telescoping actuator that includes a base stage, an intermediate stage, and an outer stage. The base stage is coupled to the base assembly, the outer stage is coupled to the scissor assembly, and the intermediate stage is arranged between the base stage and the outer stage.

A cart includes a chassis including one or more frame members, one or more casters, a first channel and a second channel coupled to the chassis, the first channel defining a longitudinal axis and the second channel defining a lateral axis. The first channel and the second channel each include a pair of guides each including a first portion and a second portion and a flat member coupling the guide to the frame members. The first portions extend substantially parallel to one another. The second portions are angled to increase a distance between the second portions as the second portions extend away from the first portions.

A vehicle system includes a first vehicle and a second vehicle. The first vehicle includes a first drive motor configured to drive one or more of a first plurality of tractive elements to propel the first vehicle, and a first cradle configured to support a product at a first end thereof for movement. The second vehicle includes a second drive motor configured to drive one or more of a second plurality of tractive elements to propel the second vehicle, and a second cradle configured to support the product at a second end thereof for movement. The first vehicle and the second vehicle move the product via at least one of the first drive motor or the second drive motor.
