AutoMate: Specialist and Generalist Assembly Policies over Diverse Geometries

TL;DR

AutoMate introduces a comprehensive learning framework that develops both specialist and generalist robotic assembly policies, demonstrating high success rates and zero-shot sim-to-real transfer across diverse assembly tasks.

Contribution

It is the first simulation-based system to learn both specialist and generalist assembly policies over diverse geometries with effective zero-shot sim-to-real transfer.

Findings

Specialist policies solve 80 assemblies with 80%+ success rate.

Generalist policy solves 20 assemblies with 80%+ success rate.

Zero-shot sim-to-real transfer performs comparably or better than simulation.

Abstract

Robotic assembly for high-mixture settings requires adaptivity to diverse parts and poses, which is an open challenge. Meanwhile, in other areas of robotics, large models and sim-to-real have led to tremendous progress. Inspired by such work, we present AutoMate, a learning framework and system that consists of 4 parts: 1) a dataset of 100 assemblies compatible with simulation and the real world, along with parallelized simulation environments for policy learning, 2) a novel simulation-based approach for learning specialist (i.e., part-specific) policies and generalist (i.e., unified) assembly policies, 3) demonstrations of specialist policies that individually solve 80 assemblies with 80% or higher success rates in simulation, as well as a generalist policy that jointly solves 20 assemblies with an 80%+ success rate, and 4) zero-shot sim-to-real transfer that achieves similar (or better) performance than simulation, including on perception-initialized assembly. The key methodological takeaway is that a union of diverse algorithms from manufacturing engineering, character animation, and time-series analysis provides a generic and robust solution for a diverse range of robotic assembly problems. To our knowledge, AutoMate provides the first simulation-based framework for learning specialist and generalist policies over a wide range of assemblies, as well as the first system demonstrating zero-shot sim-to-real transfer over such a range.
