Abstract:
PURPOSE: A sound recognition apparatus of a robot and a control method thereof are provided to improve sound correct recognition rate by determining whether the sound detected by the robot comes under to the conversation intention of a user or not. CONSTITUTION: A sound recognition apparatus of a robot comprises a sound sensing unit(110), judging module units(120,130,140), and a sound pressure measuring unit. The judging module unit determines the intension of conversation by comparing a detected sound with a pre-set reference condition. The sound pressure measuring unit measures the sound pressure of the detected sound. The judging module units determine an emergency by comparing the detected sound pressure with reference sound pressure.
Abstract:
The present invention relates to a method for driving a mining and/or construction machine, where said machine is arranged to be controlled by an operator by means of maneuvering means, where said operator, when driving said machine, provides steering commands by means of said maneuvering means for maneuvering said machine. The method comprises, when said machine is being driven in an environment having at least a first obstacle—estimating a path that, has been requested by said operator by means of said steering commands,—by means of a control system determining whether said machine when moving according to said requested path will be driven within a first distance from said first obstacle, and—when said machine, when travelling along said path, will be driven within a first distance from said first obstacle, influencing the path of said machine by means of said control system.
Abstract:
A system and method for magnetic survey uses an autonomous vehicle configured to traverse over the area in a grid pattern with a magnetometer coupled to the autonomous vehicle and configured to obtain magnetic measurements at a controlled rate, the magnetometer obtaining a uniform sampling of the magnetic measurements in each grid of the grid pattern; and a processor configured to obtain the magnetic survey based on the magnetic measurements.
Abstract:
A haulage vehicle comprises: a position calculating system (220) calculating an estimated position of its own vehicle; a position range calculating unit (201b) calculating a position range which is centered around the estimated position and in which the haulage vehicle is present with a predetermined expected probability; a maximum deviation amount calculating unit (602) calculating a maximum deviation amount indicating a highest value among the amounts of deviations between a target route of the haulage vehicle and each of points included in the position range; a target vehicle-speed decision unit (603) setting a target vehicle speed of the haulage vehicle to be relatively low when the maximum deviation amount is relatively large; and a target route-tracing unit (201g) performing control for the haulage vehicle to travel along the target route in compliance with the target vehicle speed.
Abstract:
The invention relates to a mine vehicle and a method. The mine vehicle comprises at least one scanning device for scanning surroundings of the mine vehicle and producing operational point cloud data. The mine vehicle comprises a control unit which is provided with a reference point cloud data of the mine. The control unit is configured to match the operational point cloud data to the reference point cloud data in order to determine position of the mine vehicle. The control unit further comprises a mine work plan, which is connected to the detected position of the mine vehicle.
Abstract:
The invention concerns a system configuration to make possible the autonomous operation of a vehicle (100), comprising: - a first layer (210) arranged to determine a configuration of the surroundings and, based on the said configuration of the surroundings, to generate at least one control signal for the autonomous operation of the said vehicle; - a second layer (220) arranged to adapt the said control signal from the said first layer (210) for a third layer (230); and - a first computer interface (215) arranged in communicative connection with the said first layer (210) and the said second layer (220), in which the said first computer interface (215) is arranged to transfer the said, at least one, control signal for the said operation from the said first layer (210) to the said second layer (220), and whereby the said computer interface (215) is configured according to a predetermined standard, independent of the first layer (210) and the second layer (220). The invention concerns also a method to make possible the autonomous operation of a vehicle and a vehicle (100; 11 ) adapted to make possible autonomous operation in accordance with the said system configuration.
Abstract:
An automated guided apparatus capable of accurately determining its position within a walled environment such as a mine or building. A mobile unit incorporating an inertial measurement unit (18) and a gray scale vision system processor/camera (25) is able to initialize its location and then update its location within the environment. The apparatus is especially adapted for producing tunnel plan views ("TOPES") and also for guiding equipment through such environments.
Abstract:
The invention is a system (100) and method (500) for managing a resource shared by a plurality of autonomous vehicles (103). Each vehicle (103) includes a navigator (120) for causing the vehicle (103) to travel a specified route to the resource and for generating a queue position request upon approach to the resource. A queue or fleet manager (102) establishes a queue to control access to the resource. The queue manager (102) generates a queue position in response to receipt of the queue position request from an approaching vehicle (103). Under control of the queue manager (102), autonomous vehicles (103) are passed through the queue and allowed to access the resource in a first-in, first-out manner.
