A pet robot in a shape of an animal is provided. The pet robot may include a body, a first actuator provided in the body, a rotating body provided in the body and connected to the first actuator to rotate, a second actuator fastened to the rotating body, a thigh portion connected to the second actuator at an upper portion thereof to rotate, a third actuator fastened to a lower portion of the thigh portion, and a calf portion positioned at a lower side of the thigh portion and connected to the third actuator at an upper portion thereof to rotate.

An information processing device, an information processing method, and a program are proposed that make it possible to allow an autonomous moving body to make battery replacement more easily. The information processing device includes a controller. The controller couples, in a first region, a connection terminal to the autonomous moving body. The first region is provided for ejection of a first battery included in the autonomous moving body. The connection terminal is provided for power supply and included in a power supply apparatus disposed in the first region. The controller moves the autonomous moving body with the connection terminal coupled, from the first region to a second region in which a charged second battery is disposed.

There is provided an information processing apparatus and an information processing method that can provide more useful information for an action plan of an autonomous mobile body, the information processing apparatus including an action recommendation unit configured to present a recommended action recommended to an autonomous mobile body, to the autonomous mobile body that performs an action plan based on situation estimation. The action recommendation unit determines the recommended action on the basis of an action history collected from a plurality of the autonomous mobile bodies, and on the basis of a situation summary received from a target autonomous mobile body that is a target of recommendation. The information processing method includes presenting, by a processor, a recommended action recommended to an autonomous mobile body, to the autonomous mobile body that performs an action plan based on situation estimation.

A type of a calculation process being executed internally is indicated by a motion to a user. An animal-shaped autonomous mobile object including a housing having a shape of an animal, a calculation section, and a motion controller that causes the housing to perform a motion corresponding to a type of a calculation process that the calculation section is executing.

Legged robots and methods for controlling legged robots are disclosed. In some examples, a mobile robot includes a frame, legs, and a control system. The mobile robot includes, for each leg, a motor coupled to the frame, the motor comprising a motor arm and a spring attachment point, the motor being configured to rotate the motor arm and the spring attachment point. The mobile robot includes, for each leg, a spring coupled to the spring attachment point of the motor and the leg, wherein the leg includes a track shaped to receive the motor arm, and wherein the leg is coupled to the spring such that the motor arm is within the track. The control system is configured, e.g., by virtue of appropriate programming, to control the motors to cause the mobile robot to move.

There is provided a robot device including: a head portion coupled to a trunk; four leg portions on a front left, a front right, a rear left, and a rear right coupled to the trunk; a first indirect portion that tilts the head portion left and right; and a second joint portion that rotates, with respect to the trunk, one of the leg portions on the rear left and the rear right to a front side, and the other to a rear side. It is possible to faithfully reproduce the movement of the four-legged animal by providing the first joint portion and the second joint portion.

A robotic animal puzzle is assembled from flat board pieces. The robotic animal includes a head portion. The head portion includes a neck group, a torso portion, including a holder 15 for an optional battery, multiple leg portions, and a tail portion. Those pieces and groups are connected using either interlocking mechanisms or flexible linkages to form the robotic animal-shaped puzzle. Movement and gestures may be controlled by an externally connected processor powered by an on-board battery pack. A pull and drag mechanism is provided to conveniently tune the center of mass. Slots allow the screw that connects the battery holder to slide.

The present technology relates to an autonomous moving object and an information processing method that make it possible to improve the ability in expression of the autonomous moving object. The autonomous moving object is an autonomous moving object that operates autonomously, and includes a light emission section that changes a color and brightness of a surface of the autonomous moving object, and a motion controlling section that controls a light emission pattern that is a pattern of the color and brightness of the light emission section, on the basis of a state of the autonomous moving object. The present technology can be applied, for example, to an autonomously movable robot that imitates a creature.
