用于室内人类环境的移动的操纵器可以用作执行各种任务的多功能设备,但是该技术的采用受到限制。减小尺寸、重量和成本可以促进采用,但有限制能力的风险。我们提出了一种新颖的设计,减少了尺寸,重量和成本,同时支持各种任务。核心设计包括一个两轮差动驱动移动的基地,升降机,和伸缩臂配置为实现笛卡尔运动在手臂的末端。设计扩展包括一个1度的自由度(DOF)的手腕存放的工具,一个2自由度灵巧手腕俯仰和滚动的工具,并符合夹具。我们证明我们的设计与人体测量和静态稳定性的数学模型。我们还提供了经验支持,从远程操作和自主控制的商业机器人基于我们的设计(伸展RE1从你好机器人公司)。在真实的家里完成任务。
Mobile manipulators for indoor human environments can serve as versatile devices that perform a variety of tasks, yet adoption of this technology has been limited. Reducing size, weight, and cost could facilitate adoption, but risks restricting capabilities. We present a novel design that reduces size, weight, and cost, while supporting a variety of tasks. The core design consists of a two-wheeled differential-drive mobile base, a lift, and a telescoping arm configured to achieve Cartesian motion at the end of the arm. Design extensions include a 1 degree-of-freedom (DOF) wrist to stow a tool, a 2-DOF dexterous wrist to pitch and roll a tool, and a compliant gripper. We justify our design with anthropometry and mathematical models of static stability. We also provide empirical support from teleoperating and autonomously controlling a commercial robot based on our design (the Stretch RE1 from Hello Robot Inc.) to perform tasks in real homes.
