Robot

A robot comprising:

• a spherical housing including a main housing portion, a first spherical cap portion, and a second spherical cap portion,
• wherein the main housing portion is disposed between the first spherical cap portion and the second spherical cap portion;
• an input device provided in the spherical housing;
• an output device provided in the spherical housing;
• a shaft that is provided in the main housing portion, and that couples the first spherical cap portion and the second spherical cap portion;
• a weight that is provided in the main housing portion and configured to rotate around a pivot that is orthogonal to the shaft to reciprocally move the weight in opposite directions of the pivot;
• an arm extending from the shaft in a direction orthogonal to the shaft;
• a display that is provided on the arm, and configured to display at least a portion of an image of a face of the robot;
• a first drive mechanism that rotates the pivot of the weight;
• a second drive mechanism that rotates the main housing portion around the shaft;
• and
• a control circuit that, when outputting, via the output device, a response to an input instruction received from a user, via the input device, based on a predetermined processing is determined to require a predetermined time or more,
• controls the first drive mechanism during the predetermined processing such that the first drive mechanism rotates the weight around the pivot to reciprocally move the weight in the opposite directions of the pivot.
