Abstract: The present disclosure provides a shutter speed adjusting method and apparatus or a robot with a photographing device, and a robot using the same. The method includes: obtaining a motion speed of the robot: obtaining an included angle between a motion direction of the robot and a shooting direction of the photographing device; obtaining a distance between the robot and a photographed object; and adjusting a shutter speed of the photographing device based on the motion speed, the included angle, and the distance. Through the present disclosure, the problem of blurred picture caused by the movement of the robot itself can be avoided, thereby improving the photographing quality.

Abstract: The present disclosure provides a robot-based 3D picture shooting method and system, and a robot using the same. The method includes: obtaining a distance between a photographed object and the photographing device of the robot based on a received shooting instruction; calculating an inter-axis distance based on the distance; obtaining the first picture after moving the robot for half of the inter-axis distance along the movement direction; obtaining the second picture after moving the robot for entire of the inter-axis distance from a current position along an opposite direction of the movement direction; and synthesizing the first picture and the second picture to obtain a 3D picture of the photographed object. In the process, the robot moves the photographing device according to the calculated inter-axis distance, and obtains two pictures of the left and right of the photographed object, which is not necessary to use a binocular camera.

Abstract: A method and device for controlling a display screen are provided, wherein the method includes: obtaining application deformation parameters of a current application when an application startup event or an application switching event is detected; determining screen deformation parameters of the display screen according to the application deformation parameters; controlling a mode of the display screen according to the screen deformation parameters.

Abstract: An interaction method for a flexible display screen includes: in accordance with a determination that the flexible display screen is folded, switching a display area of the flexible display screen from a first display area to a second display area, the first display area corresponding to a first display window, and the second display area corresponding to a second display window; obtaining a control on the second display window with a property of invisibility as a target control, and obtaining a first parameter of the target control; and displaying prompt information containing the first parameter of the target control on the second display window. An interaction method for a flexible display screen is further provided by the present disclosure. Applying the present disclosure, an invisible control can be prompted on the display area, thus obtaining more operations for a user, and improving the user experience.

Abstract: A method and device for controlling a display screen, wherein the method includes: obtaining remaining power information of a battery; determining screen size information corresponding to the remaining power information, wherein correspondence relations between the remaining power information and the screen size information are pre-established; and setting a current adjustable size of the display screen according to the screen size information.

Abstract: A method for controlling a wheeled robot to move along a circular trajectory includes: determining a first distance between a laser emitter and a center of a circular trajectory on a surface where the robot moves and a second, perpendicular distance from the laser emitter to the surface, calculating a radius of the circular trajectory based on the first distance and the second distance, calculating, based on the radius, a distance between a first wheel and a second wheel, a ratio of a first linear velocity of the first wheel to a second linear velocity of the second wheel, and determining a first rotational speed and a second rotational speed based on the ratio, and controlling the first servo to operate at the first rotational speed and the second servo to operate at the second rotational speed so as to drive the robot to move along the circular trajectory.
