Abstract: The present disclosure is provides a method, an apparatus and a terminal device for constructing parts together. The method includes: determining an assembly progress of an object constructed of parts; determining a currently required part according to the assembly progress; identifying, in a part photo of the object, the currently required part using a pre-trained first neural network model and marking the one or more identified currently required parts in the part photo; and displaying, via a display, a 3D demonstration animation with the marked part photo as a background image. The method is based on the existing 3D demonstration animation, which identifies the currently required part in the captured part photo and marks the identified currently required part in the part photo, and then displays the marked part photo as the background image of the 3D demonstration animation, thereby adding a prompt for the real part.

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.
