摘要:

我们提出DeepClaw作为机器人硬件和任务层次结构的可重构基准,用于机器人学习。DeepClaw基准测试旨在从机电一体化的角度研究机器人学习问题,其特点是机器人单元的最小设计,可以很容易地重新配置以托管来自不同供应商的机器人硬件,包括操纵器,夹具,相机,桌子和物体,旨在简化物理操作数据的收集和评估硬件基准测试的学习技能。我们提供了一个详细的设计,机器人细胞与现成的零件,以建立实验环境,可以托管广泛的机器人硬件通常采用机器人学习。我们还提出了一个分层的软件集成管道,包括定位,识别,抓取规划和运动规划,以简化基于学习的机器人控制,数据汇集和实验验证的可共享性和可重复性。我们提出了基准测试结果的DeepClaw系统的一个基线井字游戏任务,一个垃圾箱清除任务,和一个拼图游戏任务使用三套标准的机器人硬件。我们的研究结果表明,在DeepClaw中定义的任务可以很容易地在三个机器人单元上复制。在相同的任务设置下,所使用的机器人硬件的差异将对机器人学习的性能指标产生不可忽视的影响。所有设计布局和代码都托管在Github上,可开放获取。

英文摘要:

We present DeepClaw as a reconfigurable benchmark of robotic hardware and task hierarchy for robot learning. The DeepClaw benchmark aims at a mechatronics perspective of the robot learning problem, which features a minimum design of robot cell that can be easily reconfigured to host robot hardware from various vendors, including manipulators, grippers, cameras, desks, and objects, aiming at a streamlined collection of physical manipulation data and evaluation of the learned skills for hardware benchmarking. We provide a detailed design of the robot cell with readily available parts to build the experiment environment that can host a wide range of robotic hardware commonly adopted for robot learning. We also propose a hierarchical pipeline of software integration, including localization, recognition, grasp planning, and motion planning, to streamline learning-based robot control, data collection, and experiment validation towards shareability and reproducibility. We present benchmarking results of the DeepClaw system for a baseline Tic-Tac-Toe task, a bin-clearing task, and a jigsaw puzzle task using three sets of standard robotic hardware. Our results show that tasks defined in DeepClaw can be easily reproduced on three robot cells. Under the same task setup, the differences in robotic hardware used will present a non-negligible impact on the performance metrics of robot learning. All design layouts and codes are hosted on Github for open access.
