  • 支持复杂形状和遮挡场景,适合多臂机器人应用

机器人操作通常依赖已知的物体形状与姿态进行运动规划,但实际中几何信息常不完整,且受传感器噪声与视角遮挡影响。本文提出一种统一的模型化几何框架,融合触觉感知、建模与操作规划。创新点包括:一、引入贝叶斯优化指导触觉探索以推断物体形状,采用超椭圆逼近几何轮廓;二、自适应构建操作势能函数,编码物体几何特征以模拟准静态交互;三、提出在线常微分方程(ODE)实现基于模型预测与触觉反馈的姿态实时推理。系统在二维机器人分拣任务中部署,通过多种物体几何形态验证了框架在仿真与真实双机械臂系统中的鲁棒性与泛化能力。

原文摘要 · Abstract (English)

Robotics manipulation usually assumes that the shape and pose of the object are known to the robot prior to motion planning. However, precise geometric information is not always available in practice, and pose inference suffers from sensor uncertainties and view occlusion. In this work, we propose a unified model-based geometric framework integrating robotic haptic perception, modeling, and manipulation planning. Our novelties involve: \textit{i)} Introducing Bayesian Optimization (BO) to guide the haptic exploration for object shape inference, where superellipses are used to approximate geometric boundary; \textit{ii)} Adaptive formulation of manipulation potential encoding object geometry for quasi-static robot-object interaction; \textit{iii)} Proposing an online Ordinary Differential Equation (ODE) for real-time pose inference based on model prediction and tactile feedback. We deploy our system on a 2D robotic sorting task, and vary object geometries to validate the robustness and generalizability of our framework in both simulation and a real-world multi-arm setup.
