Description

It has the functions of processing and making decisions according to the current situation, and also has the function of accepting external manual control. They are widely used in mechanical manufacturing, teaching and other fields.

[0003] In the field of teaching, in addition to the display screen in front of the interactive robot, some robots also need to add projection function to broaden the teaching function of the interactive robot. When using traditional interactive robots, since the projector is fixed on the machine, the projection angle is not easy to adjust, so there are the following shortcomings:

[0004] First, in the teaching process, in most cases, the projection is projected onto the wall behind the robot, but in a few cases, it is necessary to project onto the oblique side wall of the robot. If the robot is directly rotated, the display screen will not be directly in the original position, thus affecting the use of the display screen. If the projector is disassembled and the direction is adjusted, the operation is cumbersome;

[0005] Second, when the ground at the location of use is not flat enough, the projector is not perpendicular to the wall being projected, and the image will be distorted, resulting in poor projection effect.

[0045] The embodiment of the present application provides an interactive robot with multi-angle projection, which solves the problem that when a traditional interactive robot is in use, the projection angle is not easy to adjust because the projector is fixed on the machine, and the projection needs to be projected on the inclined side wall of the robot. If the robot is rotated directly, the display screen will not be directly in the original position, thereby affecting the use of the display screen. If the projector is disassembled and the direction is adjusted, the operation is cumbersome. When the ground at the use location is not flat enough, the projector is not perpendicular to the projection wall, and the picture will be distorted, resulting in poor projection effect. The solution is to raise and level the bottom of the robot. This adjustment method is cumbersome, time-consuming and labor-intensive, and the projector is fixed above the robot without protection and has poor stability.

[0046] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
