[0002] When assembling the segments, the robotic arm moves the suction cup to the top of the segment, and the suction cup adsorbs the segment through vacuum or compressed air. According to the instructions of the control system, the suction cup with the segment is moved to the assembly position of the tunnel, the position of the segment is adjusted to ensure that the segment is aligned with the assembled segments, the segment is accurately placed in the predetermined position, and the segment is tightly spliced ​​with the adjacent segments through rotation or fine-tuning. After the assembly is completed, the segment is ensured to be stable through fine-tuning of the robotic arm or the use of other fixing devices. After the assembly is completed, the suction cup system releases the segment and prepares for the transportation of the next segment.
