Abstract: A robot system includes circuitry and a robot. The circuitry is configured to set, based on a plurality of workpieces that move along a conveying surface, a window corresponding to n workpieces of the plurality of workpieces, according to an inflow order that is an order in which the plurality of workpieces have moved along the conveying surface, where n>1. The circuitry is further configured to determine a picking order by an optimization algorithm, based on a position of each of the n workpieces. The picking order is an order of picking one or more of the workpieces from the conveying surface and is different from the inflow order. The circuitry is further configured to select m workpieces from the window based on the picking order, where n>m. The robot is configured to pick the selected m workpieces from the conveying surface in the picking order.

The search circuitry includes evaluation circuitry configured to calculate an evaluation value corresponding to each of the candidate positions, estimation circuitry configured to generate a calculation model showing a relationship between each of the candidate positions and the evaluation value with a regression analysis, and setting circuitry configured to set a new candidate position based on the calculation model.

Abstract: A simulation system includes circuitry configured to: determine placement of a robot with respect to another object in a virtual space, based on a placement constraint applied to the robot for executing a plurality of tasks; generate a path representing a trajectory of at least a portion of the robot or a tool operated by the robot during the tasks, based on a spatial relationship between the determined placement of the robot and the other object that satisfies the placement constraint; execute an operation program including the generated path in the virtual space in which the robot and the other object are placed; and check whether the robot interferes with the other object, based on the spatial relationship between the determined placement of the robot and the other object along the generated path in the virtual space, as a result of executing the tasks in the operation program.

Abstract: A planning system includes flow generating circuitry, confirmation circuitry, and update circuitry. The flow generating circuitry is configured to generate a task flow which includes work tasks predetermined based on a concurrent execution constraint with respect to concurrent execution of tasks performed by robots and connection tasks to be connected to the work tasks. The confirmation circuitry is configured to determine whether at least one of the robots interferes with an object in the connection tasks. The update circuitry is configured to update the concurrent execution constraint when the at least one of the robots is determined to interfere with the object.
