  • 将机器人设计与驱动映射为算子学习问题,实现跨设计泛化。

连续机器人可在狭小空间实现灵巧操作,但实时操控需高效精确的模型。传统物理模型计算成本高且因未建模效应易出错,现有基于学习的方法通常难以泛化到不同机器人。本文将腱驱动连续机器人的代理建模问题转化为算子学习:从机器人设计参数与腱驱动输入映射到末端配置。该框架使单一模型可泛化至大量机器人设计。我们提出四种新型神经算子架构——两种基于DeepONet,两种基于FNO——在仿真数据上训练以预测机器人构型。所有架构均实现高精度,并支持跨设计快速准确泛化。结果表明,算子学习为连续机器人力学在设计空间提供了有效且通用的代理模型,可加速手术与工业应用中的控制、规划与设计优化。

原文摘要 · Abstract (English)

Continuum robots enable dexterous manipulation in constrained environments, but require accurate and efficient models for real-time manipulation and control. Traditional physics-based models can be computationally expensive and may suffer from inaccuracies due to unmodeled effects, while current learning-based methods often generalize poorly beyond the specific robot on which they are trained. We present a formulation of surrogate modeling for tendon-driven continuum robots as an operator learning problem that maps robot design parameters and tendon actuation inputs to resulting configurations. This formulation enables a single trained model to generalize across a large class of robot designs. We develop four novel neural operator architectures--two based on Deep Operator Networks (DeepONets) and two based on Fourier Neural Operators (FNOs)--and train them on simulation data to predict robot configurations. All architectures achieve good accuracy while allowing for fast and accurate generalization across designs. Our results demonstrate that operator learning provides an effective and generalizable surrogate for continuum robot mechanics in the design space, enabling fast modeling for control, planning, and design optimization in surgical and industrial applications.
