摘要:

设想一个机器人能够从以任意构型呈现给它的独立零件中装配出一个可正常工作的产品。设计这样的机器人系统是一个复杂问题,面临若干开放性挑战。为绕开这些挑战,当前一代装配系统需要大量系统集成工作,以提供装配所需的结构化环境和精度。这些系统主要负责零件分离、零件配套和零件检测,而这些任务通过智能化的系统设计来完成。本文提出在对结构化环境要求最低的情况下自主装配一个齿轮箱。装配零件被随机放置在机器人的二维工作环境中。所提出的系统利用多种不同的操作技能,例如用于抓取的滑动、手内操作以及插入,以完成齿轮箱装配。所有这些任务都使用视觉、触觉和力/力矩(F/T)传感器以闭环方式运行。我们开展了大量硬件实验,以证明所提方法及整个系统的鲁棒性。补充视频见 https://www.youtube.com/watch?v=cZ9M1DQ23OI。

英文摘要:

Imagine a robot that can assemble a functional product from the individual parts presented in any configuration to the robot. Designing such a robotic system is a complex problem which presents several open challenges. To bypass these challenges, the current generation of assembly systems is built with a lot of system integration effort to provide the structure and precision necessary for assembly. These systems are mostly responsible for part singulation, part kitting, and part detection, which is accomplished by intelligent system design. In this paper, we present autonomous assembly of a gear box with minimum requirements on structure. The assembly parts are randomly placed in a two-dimensional work environment for the robot. The proposed system makes use of several different manipulation skills such as sliding for grasping, in-hand manipulation, and insertion to assemble the gear box. All these tasks are run in a closed-loop fashion using vision, tactile, and Force-Torque (F/T) sensors. We perform extensive hardware experiments to show the robustness of the proposed methods as well as the overall system. See supplementary video at https://www.youtube.com/watch?v=cZ9M1DQ23OI.
