A positioning method of intelligent plastering robot head

When using an intelligent plastering robot to perform plastering operations on a completed room, in order to ensure the final smoothness of the wall, the most important step is to ensure that the plastering robot's wiper head is approximately absolutely parallel to the wall and is away from the wall. The distance is always consistent within the error range. This article uses a low-cost laser liner and CCD module to achieve high-precision real-time tracking, positioning and adjustment of the plastering robot head, and to realize the smoothness plastered walls. the plastering thickness of a whole wall reaches 2mm. The average flatness error is ± 0.2mm.(Abstract)
