AssemblyBench: Physics-Aware Assembly of Complex Industrial Objects

2026-05-13 · Source: Takara TLDR - Daily AI Papers · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Robotics & Autonomous Systems, Manufacturing & Industrial · Depth: Expert, medium

Summary

AssemblyBench introduces a new synthetic dataset comprising 2,789 industrial objects, each with multimodal instruction manuals, corresponding 3D part models, and detailed part assembly trajectories. This dataset addresses limitations in existing resources that often simplify shape complexities and assembly motions in industrial contexts. Alongside the dataset, the authors propose AssemblyDyno, a transformer-based model designed to predict both assembly order and 6-DoF part assembly trajectories. AssemblyDyno leverages instructional manuals and 3D part shapes to make these predictions. The model demonstrates superior performance compared to previous methods in assembly pose estimation and trajectory feasibility, with the latter validated through physics-based simulations.

Key takeaway

For research scientists developing robotic assembly systems, this work highlights the importance of physics-aware trajectory planning and multimodal instruction processing. You should consider integrating datasets like AssemblyBench and models like AssemblyDyno to improve the realism and feasibility of your assembly simulations and robotic operations, particularly for complex industrial objects.
