This project will study the use of sliding friction and impact dynamics for a variety of parts sorting, feeding, and transport applications at macro and mesoscopic scales. The investigation will be embodied in a six-degree-of-freedom vibratory plate that can be programmed to move with arbitrary periodic small-amplitude motion profiles. Parts resting on the plate move relative to the plate based on their geometry, mass distribution, and friction and restitution coefficients, as well as the programmable motion of the plate.The novelty of the proposed work is in using the programmability of the plate's motion to take full advantage of friction and impact effects, allowing it to perform a variety of functions simply by changing the software. These include the use of motion-controlled programmable force fields to allow individual control of the planar motion of multiple parts on the plate, parts sorting and singulation, and sensorless positioning and orienting of parts on the plate in three dimensions by creating programmable ``potential wells'' to trap the parts. The results of this research will be a better theory of the physics of vibration-induced motion as well as new technologies for industrial automation. We will recruit undergraduates to participate through independent projects and REU's. Graduate students involved in this research will benefit from participation in the interdisciplinary Institute on Complex Systems. Outreach plans include presentations and mentoring of science projects at the local high school.

该项目将在宏观和细观尺度上研究滑动摩擦和冲击动力学在各种零件分拣、进料和运输应用中的应用。该研究将体现在一个六自由度的振动板，可以编程移动任意周期小振幅运动轮廓。放置在板上的零件根据其几何形状、质量分布、摩擦和恢复系数以及板的可编程运动相对于板移动。所提出的工作的新颖之处在于利用板的运动的可编程性来充分利用摩擦和冲击效应，允许它通过简单地改变软件来执行各种功能。其中包括使用运动控制的可编程力场，允许单独控制板上多个零件的平面运动，零件分类和模拟，以及通过创建可编程的“电位井”来捕获零件，在三维空间中对板上零件进行无传感器定位和定向。这一研究结果将为振动诱发运动的物理学提供更好的理论，并为工业自动化提供新技术。我们将通过独立项目和REU招募本科生参与。参与这项研究的研究生将受益于参与跨学科的复杂系统研究所。拓展计划包括在当地高中进行科学项目的演讲和指导。
