论文摘要

我们提出了一个仅使用世界上RGB视图的机器人操纵器的无冲突控制系统。桌面场景的感知输入由RGB摄像机的多个图像(无深度)提供,该图像是手持式或安装在机器人最终效应器上的。类似NERF的过程用于重建场景的3D几何形状,从该过程中,欧几里得完整签名的距离函数(ESDF)被计算出来。然后使用模型预测控制算法来控制操纵器以达到所需的姿势,同时避免ESDF中的障碍物。我们在我们的实验室收集和注释的真实数据集上显示了结果。

We present a system for collision-free control of a robot manipulator that uses only RGB views of the world. Perceptual input of a tabletop scene is provided by multiple images of an RGB camera (without depth) that is either handheld or mounted on the robot end effector. A NeRF-like process is used to reconstruct the 3D geometry of the scene, from which the Euclidean full signed distance function (ESDF) is computed. A model predictive control algorithm is then used to control the manipulator to reach a desired pose while avoiding obstacles in the ESDF. We show results on a real dataset collected and annotated in our lab.
