Abstract: A robot having a spherical casing, a control circuit and a communication circuit configured to connect to an external server is provided. The robot further includes a set of wheels included in the spherical casing, which comes into contact with an inner surface of the spherical casing and configured to rotate the spherical casing when the driving wheels are driven. The control circuit is configured to, when determining that performing a predetermined processing in response to an input instruction received from a user requires a predetermined amount of time or more, causes each of the set of driving wheels to rotate in opposite directions from each other to rotate the spherical casing during the predetermined processing. When the predetermined processing is complete and a response is to be output, the control circuit stops rotation of the spherical casing with the set of wheels facing toward the user.

Abstract: A processor determines, by referring to a memory, which of a plurality of behavior types a behavior type executed by a robot when a first sensor detects an obstacle is; determines a type of the obstacle detected by the first sensor; decides whether first behavior for increasing opportunities of interaction with the user or second behavior for handling the obstacle is performed, based on the behavior type executed by the robot when the first sensor detects the obstacle and the type of the obstacle detected by the first sensor; and controls the robot to cause the robot to execute the decided behavior.

Abstract: 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.

Abstract: 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.

Abstract: If an interaction target includes a child and an adult, and if an interaction amount is greater than or equal to a threshold, a robot asks the adult if the adult allows the robot to continue interacting with the child. If the target includes the child and the adult, and if the interaction amount is less than the threshold, the robot requests to the adult that the adult and the child continue interacting with the robot. If the target includes only the child, and if the interaction amount is greater than or equal to the threshold, the robot stops interacting with the child. If the target includes only the child, and if the interaction amount is less than the threshold, the robot leads the child to continue interacting with the robot.

Abstract: A robot is provided. When a value obtained by excluding a gravitational component from an acceleration detected by an acceleration sensor is continuously less than a reference value for a certain time, a travelling state of the robot is determined as frictional surface travelling. A control circuit calculates an attitude angle of the robot from an angular velocity in a pitch direction, which is detected by an angular velocity sensor. When the calculated attitude angle is a lower limit angle or more for a determination time, the control circuit sets the attitude angle at the end of the determination time as an attitude control angle. When the travelling state of the robot is determined as the frictional surface travelling, the control circuit moves a counterweight frontward by a movement amount corresponding to the attitude control angle.

Abstract: 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.

Abstract: If an interaction target includes a child and adult, if a remaining power amount is less than or equal to a first threshold, and if an interaction amount is greater than or equal to a second threshold, a robot asks the adult if the adult allows the robot to move to a charger. If the target includes the child and adult, if the remaining power amount is less than or equal to the first threshold, and if the interaction amount is less than the second threshold, the robot asks the child if the child allows the robot to move to the charger. If the target includes only the child, if the remaining power amount is less than or equal to the first threshold, and if the interaction amount is greater than or equal to the second threshold, the robot moves to the charger. If the target includes only the child, if the remaining power amount is greater than the first threshold, and if the interaction amount is greater than or equal to the second threshold, the robot stops interacting with the child.
