An Enhanced Collision-Aware Min-Max A* Path Planning Algorithm (ECMMA*) in Automated Calibration Production Lines

In actual production, the collisions between components and surrounding objects often occur on automatic calibration lines. To solve these problems, an enhanced collision-aware min-max A* path planning algorithm (ECMMA*) based on the spatial and temporal features of component locations is proposed in this paper. ECMMA* determines in real time whether there is interference between the running path of the components and the coordinates of the surrounding objects. It also takes into account overall costs to optimize the path planning for automated calibration production lines. The experimental results show that the proposed method effectively reduces the distance and time of equipment movement, improves production efficiency and resource utilization, and ensures the effectiveness and safety of the paths.
