Automating the assembly of objects from their parts is a complex problem with innumerable applications in manufacturing, maintenance, and recycling. Unlike existing research, which is limited to target segmentation, pose regression, or using fixed target blueprints, our work presents a holistic multi-level framework for part assembly planning consisting of part assembly sequence inference, part motion planning, and robot contact optimization. We present the Part Assembly Sequence Transformer (PAST) -- a sequence-to-sequence neural network -- to infer assembly sequences recursively from a target blueprint. We then use a motion planner and optimization to generate part movements and contacts. To train PAST, we introduce D4PAS: a large-scale Dataset for Part Assembly Sequences (D4PAS) consisting of physically valid sequences for industrial objects. Experimental results show that our approach generalizes better than prior methods while needing significantly less computational time for inference.

将物体的装配从其组成部分自动化是一个复杂的问题，具有生产制造、维护和再生利用等无数应用。我们的研究提出了一个整体多层次的部件装配规划框架，包括部件装配顺序的推理、部件运动规划和机器人接触优化。我们通过引入大规模部件装配序列数据集（D4PAS）来训练Part Assembly Sequence Transformer （PAST）神经网络，实验结果表明我们的方法相比之前的方法具有更好的泛化性能，且推理过程所需的计算时间显著减少。
