A self-propelled device is disclosed that includes a center of mass drive system. The self-propelled device includes a substantially cylindrical body and wheels, with each wheel having a diameter substantially equivalent to the body. The self-propelled device may further include an internal drive system with a center of mass below a rotational axis of the wheels. Operation and maneuvering of the self-propelled device may be performed via active displacement of the center of mass.

A device may determine, based on image data of an environment that includes a ground surface, depth information indicating distances from a vehicle to different areas of the ground surface. The device may generate, based on the depth information, an overlay to indicate a range of distances from the vehicle. The range of distances may be associated with an area. The device may provide, for display, a video feed including the image data with the overlay on the ground surface. The overlay may provide the perception of depth, with respect to the area, during an operation of the vehicle.

Systems, methods, and computer-readable media are disclosed for automated multimodal delivery. Example methods may include determining information associated with the delivery; determining, based on at least a first portion of the information, that a first confidence level indicative of a delivery capability using a first vehicle is above a first threshold; and determining, based on at least a second portion of the information, a second confidence level indicative of a delivery preference for delivery using the first vehicle relative to a second vehicle.

Anti-collision airport system including a motorized mobile device to be moved close to an aircraft. The system includes a database to record structural characteristics of categories of aircraft and structural characteristics of the motorized mobile device. The controller is configured to identify a category corresponding to the aircraft and a positioning of the motorized mobile device with respect to the aircraft, search and retrieve, from the database, structural characteristics associated with the category corresponding to the aircraft and structural characteristics of the motorized device, calculate a trajectory for the movement of the motorized mobile device on the basis of the structural characteristics of the aircraft and of the motorized mobile device and of the positioning of the motorized mobile device with respect to the aircraft, and control the motorized mobile device according to the calculated trajectory.

A docking method executable by a mobile device is provided. The docking method includes obtaining a stored target location of a docking station, and navigating to the target location. The docking method also includes: during the navigation and/or at the target location, based on a determination that a guidance signal is not detected, performing a regional search. The docking method also includes: during the navigation, or at the target location, or during the regional search, based on a determination that the guidance signal is detected, moving, under the guidance of the guidance signal, to the docking station. Performing the regional search includes determining a basic search zone, searching for the guidance signal while moving along boundaries of the basic search zone, and based on a determination that the guidance signal has not been detected when a termination condition is satisfied, terminating the regional search.

In a method or system in which an imaging element views navigation elements for e.g. navigation, the navigating elements may not be positioned optimally. Positions may exist in which the same angles exist from the imaging element to the same or similar navigating elements, whereby the positions are not unique. Navigation elements may then be repositioned, added or removed to make the positions unique.

A multi-robotic live production and webcast videographic system includes at least one videographic robot operating automatically and performing videography on spot through specific rules or by its own ability after learning; a main controller being a remote control device for receiving video or voice messages from at least one videographic robot; the receiving messages and production data of the main controller being stored in an videographic database; and at least one operation mode unit for determining operation modes of the videographic robot so that the videographic robot acts according to the operation mode; the operation mode unit including an operation mode database which stores various specific operation modes including a logic mode, an AI mode and a scenario mode so that the videographic robot may move to a desire position and adjust the shooting angle according to a selected operation mode.

A method for operating a multi-agent system that includes multiple robots, each of the robots cyclically performing the following: starting from an instantaneous system state, ascertaining possible options, the options defining actions by which a transition may be achieved from an instantaneous system state to a subsequent system state; for each of the possible options, ascertaining action costs for performing an action specified by the option; performing an auction, the action costs values ascertained for each option being taken into consideration by each of the other robots; and performing an action, which corresponds to one of the options, as a function of all cost values ascertained or received for the relevant option, the action costs for a particular option each taking an experience parameter into consideration, which is a function of costs for past actions assigned to the particular option previously carried out by the multiple robots.

An apparatus for de-icing a pathway, the apparatus comprising a frame including a set of wheels, a salt dispenser, a servo attached to the salt dispenser, one or more motors, the motors attached to at least one of the set of wheels, and a microcontroller communicatively coupled to the servo and the one or more motors, wherein the microcontroller instructs the servo to operate the salt dispenser and activates the one or more motors to drive the at least one of the set of wheels.

The present invention relates to a sampling based optimal tree planning method, a recording medium storing a program for executing the same, and a computer program stored in the computer-readable recording medium for executing the same, more particularly to, a sampling based optimal tree planning method, a recording medium storing a program for executing the same, and a computer program stored in the computer-readable recording medium for executing the same for enabling real-time path planning by reducing the number of nodes that require calculation by excluding state values corresponding to input values that a mobile robot cannot select from the calculation and sampling some state values of a set of state values feasible for the robot when planning a path in a tree structure.
