Abstract: A robot system includes a robot controlled by a computer. The robot includes a control device and an observation device. The computer detects a plurality of objects in a periphery by using observation information obtained by observation of the observation device, stores first state information of each of the plurality of detected objects, predicts future states of the plurality of detected objects from the first state information by using a first model for predicting a future state of an object, generates second state information of the periphery obtained by observation of the plurality of detected objects, predicts a future state of the robot from the second state information by using the first model, and determines a future action of the robot based on a given action target, the predicted future states of the plurality of objects, and the predicted future state of the robot.

Abstract: An information processing apparatus and an information processing method capable of accurately recognizing an object to be sensed are provided.
One or a plurality of learning models are selected from among learning models corresponding to a plurality of categories, a priority of each of the selected learning models is set, observation data obtained by sequentially compounding pieces of sensor data applied from a sensor is analyzed using the learning model and the priority of the learning model, a setting of sensing at a next cycle is selected based on an analysis result, predetermined control processing is executed in such a manner that the sensor performs sensing at the selected setting of sensing, and the learning model corresponding to the category estimated as the category to which a current object to be sensed belongs with a highest probability is selected based on the categories to each of which the previously recognized object to be sensed belongs.-

Abstract: To generate a prediction image in which an outline of an object is clear and existence of the object is easily recognized, the image prediction system that generates a future prediction image and includes a gaze unit, a working memory unit, a control unit, and a generation model unit. The gaze unit controls a region including an object included in an observation image as a first gaze region. The working memory unit controls the first gaze region as a second gaze region when a difference in the first gaze region between the observation image and a prediction image is equal to or less than a predetermined value. The generation model unit generates prediction images of the first gaze region and the second gaze region. The control unit integrates the prediction image of the first gaze region and the prediction image of the second gaze region to generate a prediction image.
