摘要： A path planning system for an agricultural machine to automatically travel inside and outside a field includes a storage to store a map of a region including fields and roads, and a processor to generate a path for the agricultural machine on the map. The map includes attribute information representing, for each of the roads, at least one of whether the road is an agricultural road, whether the road is a road along a specific feature, or whether the road is a road where satellite signals from GNSS satellites are receivable. The processor is configured or programmed to generate at least one of a path including an agricultural road with priority, a path including a road along the specific feature with priority, or a path including, with priority, a road where the satellite signals are receivable, as the path for the agricultural machine based on the attribute information.

摘要： Systems, methods, and computer-readable media for dynamic changes to both a learned control policy in the event of a change in the environment (e.g., introduction of a new or unseen obstacle). Rather than having to implement an entirely new policy (and a new global Q table), which can delay performance of tasks by agent(s), the present embodiments allow for a reduced delay in updating local Q table(s) based on detection of a new change in the environment. Locally changing the policy allows for more efficient updating of the policy based on changes in the environment, rather than globally changing the Q table after each change. Particularly in an event with multiple changes in the environment, the present embodiments increase efficiency in updating local and global Q tables while also reducing a delay in providing new instructions to the agent(s) in completing tasks.

摘要： An information processing system according to an embodiment of the present disclosure includes a first information processing device to be provided to a movable body and a second information processing device to be provided to a portion that differs from the movable body. The first information processing device includes a sensor portion, a generation portion, a control portion, and an integration portion. The sensor portion senses a first external environment. The generation portion uses sensor data acquired from the sensor portion to generate a first map. The control portion controls motion of a manipulator on the basis of the first map. The integration portion uses position information of inside the first external environment, with which portion the manipulator is in contact, integrates the first map and a second map acquired from the second information processing device with each other, and generates an integration map.

摘要： This disclosure relates generally to method and system for multi-object tracking and navigation without pre-sequencing. Multi-object navigation is an embodied Al task where object navigation only searches for an instance of at least one target object where a robot localizes an instance to locate target objects associated with an environment. The method of the present disclosure employs a deep reinforcement learning (DRL) based framework for sequence agnostic multi-object navigation. The robot receives from an actor critic network a deterministic local policy to compute a low-level navigational action to navigate along a shortest path calculated from a current location of the robot to the long-term goal to reach the target object. Here, a deep reinforcement learning network is trained to assign the robot with a computed reward function when the navigational action is performed by the robot to reach an instance of the plurality of target objects.

摘要： The present disclosure relates to a method for stochastic inspections on power grid lines based on unmanned aerial vehicle-assisted edge computing. According to the method, a stochastic distributed inspection unmanned aerial vehicle is adopted to acquire video images on a target power grid area, which can reduce funds and time costs of inspections. With assistance of superior unmanned aerial vehicle, a goal is to minimize energy consumption of an unmanned aerial vehicle system and extend operation time of the unmanned aerial vehicles under same payload conditions, while processing video image data collected from the inspection unmanned aerial vehicles. The near-far effect generated by communications between mobile unmanned aerial vehicles is eliminated by introducing a NOMA, and position coordinates, system resource allocations and task offload decision schemes are solved by using a method of combining a DDPG algorithm in a Deep reinforcement learning with a genetic algorithm.

摘要： To provide an apparatus and a method that efficiently determines a best path on which a moving apparatus such as a walking robot can travel safely. The apparatus includes a path planning unit that determines a travel path of the moving apparatus such as a walking robot, and the path planning unit is configured to calculate a path cost for each of a plurality of path candidates by applying a cost calculation algorithm in which a path that enables more stable traveling has a lower cost and to determine the path candidate having the path cost that has been calculated to be the lowest cost as the travel path that is best. The path planning unit sets a plurality of sampling points in a path, calculates a cost corresponding to each sampling point by applying the cost calculation algorithm in which the cost becomes higher as the difference between landing heights of the left and right legs at each sampling point becomes larger, and calculates an addition value of the costs of the sampling points as the path cost.

摘要： A path planning method and a biped robot using the same are provided. The method includes: generating a candidate node set for a next foot placement based on a biped robot's own parameters and joint information of a current node, adding valid candidate nodes in the candidate node set to a priority queue so as to select optimal nodes for realizing next node expansion. These optimal nodes are output to generate a foot placement sequence from an initial node to a target node, which can greatly reduce the search amount for path nodes when the robot's legs intersect and touch the ground, thereby improving the efficiency of path planning.
