摘要： A topic providing device includes a candidate topic extractor, a provided topic determiner, a voice synthesizer, and a speaker. When a determination is made that a parent and child are conversing and that there is a need to provide a new topic to the parent and child, based on a conversation history database and a child activity database storing at least one activity name indicating an activity the child was engaged in for a first predetermined period of time, the candidate topic extractor extracts at least one candidate topic that corresponds to the at least one activity name in the child activity database and does not correspond to an activity name included in text data recorded in a first database. From the at least one candidate topic, the provided topic determiner selects one topic to provide to the parent and the child. The voice synthesizer generates voice data containing the one topic. The speaker outputs the voice data.

摘要： A robot including a spherical housing made up of a main housing portion, a first spherical cap portion, and a second spherical cap portion. The main housing portion is disposed between the first spherical cap portion and the second spherical cap portion. The robot further including a weight that is provided in the main housing portion and configured to rotate around a pivot that is orthogonal to a shaft connecting the spherical cap portions. When outputting a response to an input instruction received from a user, via an input device, based on a predetermined processing is determined to require a predetermined time or more, a robot controls a first drive mechanism during the predetermined processing such that the first drive mechanism rotates a weight around the pivot to reciprocally move the weight in the opposite directions of the pivot.

摘要： A robot includes a main casing, a first spherical cap and a second spherical cap, and a shaft linking the spherical caps. The robot further includes a display, a first driving mechanism causing the first and second spherical caps to be rotated by the shaft, and a second driving mechanism that causes the main casing to be rotated. The robot also includes a control circuit and an electric power source, charged by electric power from an external charger. If the remaining electric power of the electric power source is lower than or equal to a predetermined value, the second driving mechanism is controlled to stop rotation of the main casing, and the first driving mechanism is controlled to switch a rotational direction of the first spherical cap and the second spherical cap, causing the display to be reciprocally moved in a vertical direction.

摘要： A spherical shaped robot with a drive mechanism and a weight drive mechanism is provided. If a distance from the robot to an object is less than a predetermined value, the robot executes a pivot turn mode. In the pivot turn mode, the robot controls the drive mechanism to stop linear movements of the robot, controls the weight drive mechanism to tilt the weight to a first side representing one of the right hand side and left hand side of the robot, controls the drive mechanism to cause a forward movement of the robot with the weight tilted to the first side, controls the drive mechanism to stop the forward movement of the robot, controls the weight drive mechanism to tilt the weight to a second side different from the first side, and controls the drive mechanism to cause a backward movement of the robot with the weight tilted to the second side.

摘要： A robot includes a range finding sensor that measures a distance from the robot to an object facing a display each time the range finding sensor rotates through a predetermined angle. If a difference between a first distance previously measured and a second distance subsequently measured is a first predetermined value or greater, information is stored in a memory to indicate that a down-step is located in a direction defined by a turning angle of the robot when the first distance is measured at a position that is separated from the robot by the first distance. When rotating and moving the main casing in a direction in which the down-step is located, the robot is caused to make a pivot turn first. Subsequently, the main casing is rotated to move in the direction in which the down-step is located by a distance smaller than the first distance.

摘要： In a robot, after a first value indicating acceleration in the up-and-down axis direction output from an acceleration sensor exceeds a certain threshold value, when any of the first value indicating the acceleration in the up-and-down axis direction, a second value indicating the acceleration in the front-and-back axis direction, and a third value indicating the acceleration in the left-and-right axis direction is determined to exhibit variation exceeding a certain width for a fixed period, the robot determines that a housing of the robot is being held by a user.

摘要： A robot includes a control circuit that detects a changing maximum value of a pitch angle, when the robot moves to a predetermined target point by rotating its main body. The control circuit determines a minimum control amount corresponding to the maximum value of the pitch angle, when the robot arrives at a predetermined distance short of the predetermined target point. The control circuit generates a deceleration control amount for the second drive mechanism that is greater than or equal to the minimum control amount, according to a remaining distance to the predetermined target point. The control circuit decelerates the rotation of the main body by controlling the second drive mechanism in accordance with the deceleration control amount.
