Reporters obtained the following quote from the background information supplied by the inventors:“With the economy developing and the technology advancing, a p ool cleaning robot gradually takes a role in daily life and increasingly grows p opular. A control board, a significant part of the pool cleaning robot,primaril y serves to control the pool cleaning robot to work.“In the related art, it is common practice to vertically attach the control boar d of the pool cleaningrobot to an inner wall of a housing. Accordingly, an acce lerometer and a gyroscope on the control boardfail to properly sense a real-tim e state of the pool cleaning robot or precisely determine a coordinateposition of the pool cleaning robot. Therefore, a working efficiency of the pool cleaning robot is reduced,and a time cost is increased.”
