    Abstract: 予測された複数の自車進路候補の中から安全性と走行効率との調和のとれた自車進路の決定を可能にすることを課題とし、予測された複数の自車進路候補の各々に対する自車の安全性を評価した安全性評価値と自車進路候補の各々の走行効率を評価した効率評価値とを演算し(ステップS403,S409)、複数の自車進路候補の中から、安全性評価値が設定された所定値を上回る安全条件を満たし(ステップS412のYes)、最大の効率評価値を有する自車進路候補を自車の走行可能進路として選択する(ステップS413のYes,ステップS414)ようにし、安全性評価値を許容するための所定値を状況に応じて適正に設定することで(ステップS401)、例えば安全基準を満たす範囲内で安全性は若干低下しても早く目的地に到達するための追い越し進路の選択を許容する等の自車進路の決定が可能となるようにした。

    Abstract: PROBLEM TO BE SOLVED: To provide a robot and so forth capable of executing a task in an appropriate condition from the viewpoint of execution economy even when the task state is changed.
    SOLUTION: A cost is evaluated that represents load or work required for a robot to execute a new task, and the cost information indicating this cost is sent to a support server 200 (bid procedure). The support server 200 specifies the robot having the lowest cost and sends an execution instruction for executing the new task to the specified robot. The robot executes the task according to the execution instruction (contract procedure). By employing this task bid and contract system, a specified task is executed by an adequate robot R among a plurality of robots R in consideration of the execution economy of the specified task.

    Abstract: PROBLEM TO BE SOLVED: To generate the optimum route in a searching space expressed by grids.
    SOLUTION: This route planning device 13 is provided with: an edge generating unit 21 that, on the assumption that each grid is a node, and that the cost from a starting point to an arbitrary node is that of the arbitrary node, and that the minimum cost node among the top end nodes positioned at the top end of an edge is a notable node, extends the edge up to neighboring nodes positioned at the front and obliquely right and left fronts of the notable node; an edge cost calculating/reading-out unit 22 that regards such a node as the standard node that is counted up by a predetermined number in the direction of the starting point along the route from the notable node, and reads out the shortest distance (first distance) from the standard node to the neighboring node and the shortest distance (second distance) from the standard node to the notable node from a database; a route cost calculating unit 23 that calculates the route cost from the starting point to the neighboring node as the sum of the costs of the route-composing edges; and a route determining unit 24 that selects the route of the minimum cost from the starting point to the terminating point.
