摘要:

我们提出了一个受约束的合作移动代理(CCMA)系统的概念,它由多个轮式移动代理受一个被动的运动链约束。这种移动机器人系统是模块化的,被动运动链可以很容易地替换为不同的设计和形态,以适应不同的功能和任务的适应性。仅依赖于移动代理的致动,该移动机器人系统可以操纵或定位末端执行器。然而,系统的复杂性,由于存在几个移动代理,被动的运动链和受约束的协作操作的性质,需要开发一个优化框架。因此,我们提出了一个优化框架,该系统的正向仿真和运动控制。有了这个优化框架,部署的移动代理,驱动方案,被动运动链的设计和形态的数量可以很容易地改变,这加强了移动机器人系统的模块化和协作方面。我们目前的结果,在模拟中,空间4自由度到6自由度CCMA系统的例子。最后,我们提出了两个不同的制造4自由度原型,这表明不同的驱动方案,控制和协同操作的末端执行器的实验定量结果。

英文摘要:

We present a concept of constrained collaborative mobile agents (CCMA) system, which consists of multiple wheeled mobile agents constrained by a passive kinematic chain. This mobile robotic system is modular in nature, the passive kinematic chain can be easily replaced with different designs and morphologies for different functions and task adaptability. Depending solely on the actuation of the mobile agents, this mobile robotic system can manipulate or position an end-effector. However, the complexity of the system due to presence of several mobile agents, passivity of the kinematic chain and the nature of the constrained collaborative manipulation requires development of an optimization framework. We therefore present an optimization framework for forward simulation and kinematic control of this system. With this optimization framework, the number of deployed mobile agents, actuation schemes, the design and morphology of the passive kinematic chain can be easily changed, which reinforces the modularity and collaborative aspects of the mobile robotic system. We present results, in simulation, for spatial 4-DOF to 6-DOF CCMA system examples. Finally, we present experimental quantitative results for two different fabricated 4-DOF prototypes, which demonstrate different actuation schemes, control and collaborative manipulation of an end-effector.
