Robot and task execution system

A robot including a controller which controls the robot to execute a task by making autonomous motions according to communication with a support server provided with a task database, the controller comprising:

• a first processing element configured to:
• communicate with the support server and recognize a content of a designated task among a plurality of tasks stored in the task database;
• recognize whether the robot is executing another task different from the designated task;
• evaluate a cost indicating a labor or load required for the robot to execute the designated task, wherein the cost is evaluated to be higher when the robot is recognized to be executing the other task different from the designated task as compared to when the robot is not recognized to be executing the other task different from the designated task;
• and communicate with the support server and store the evaluated cost in the task database;
• and
• a second processing element configured to recognize whether the cost for the robot to execute the designated task stored in the task database is a lowest cost for execution of the designated task in a robot group containing other robots, and to control the motions of the robot to execute the designated task on a condition that the cost therefore has been recognized to be the lowest, wherein the first processing element is further configured to recognize a priority level of the designated task as the content thereof, when the robot is recognized to be executing the other task different from the designated task, to recognize whether the priority level of the designated task is higher than a priority level of the other task being executed by the robot, and to evaluate the cost of the robot to execute the designated task to be higher when the priority level of the designated task is lower than the priority level of the other task as compared to the cost when the priority level of the designated task is higher than the priority level of the other task.

A task execution system, comprising:

• a support server provided with a task database, the task database storing a content of each of a plurality of tasks, and
• a plurality of robots executing the plurality of tasks by making autonomous motions according to communication with the support server,
• wherein
• each of the plurality of robots is provided with a controller, the controller including:
• a first processing element configured to:
• communicate with the support server and recognize a content of a designated task among the plurality of tasks stored in the task database;
• evaluate a cost indicating a labor or load required for the robot to execute the designated task;
• communicate with the support server and store the evaluated cost for the robot to execute the designated task in the task database;
• evaluate the cost of a scheduled execution task for the robot when the designated task has been executed and evaluate the cost of the scheduled execution task for the robot when the designated task is not executed after an execution duration of the designated task, respectively;
• evaluate the cost for the robot to execute the designated task to continuously or step-wisely increase as the cost of the scheduled execution task when the designated task has been executed becomes higher as compared to the cost of the scheduled execution task when the designated task is not executed;
• and evaluate the cost for the robot to execute the designated task to continuously or step-wisely decrease as the cost of the scheduled execution task when the designated task has been executed becomes lower as compared to the cost of the scheduled execution task when the designated task is not executed;
• and
• a second processing element configured to communicate with the support server and recognize whether the cost for the robot to execute the designated task stored in the task database is a lowest cost for execution of the designated task as compared to the evaluated cost for execution of the designated task for other robots in the plurality of robots, and to control the motions of the robot to execute the designated task on a condition that the cost thereof has been recognized to be the lowest.
