摘要：

本发明提供一种光控抓取装置,至少包含底座,其中,该底座上设有手臂,该手臂上设有至少可产生抓取形变的单元,所述抓取单元内起形变作用的部件由光致形变材料制成。本发明还提供了一种抓取方法,即利用光照射抓取装置的抓取单元上的光致形变材料使该抓取单元发生形变从而实现抓取功能。本发明中的光控抓取装置执行机构以及操作机构都相对简单,其尺寸可以做到较小;本发明提供的抓取方法还具有快速、精确、环保、能耗小的优点,并且具有可远程操作等其他驱动方式所不具备的特点。

Abstract：

The invention provides a photo gripping device, comprising a pedestal at least, wherein the pedestal is provided with an arm, the arm is provided with a unit capable of producing gripping deformation, and the effective deformation part in the gripping unit is made by photoinduced deformation material. The invention also provides a gripping method, namely light irradiates the photoinduced deformation material on the gripping unit of the gripping device to cause the gripping unit to deform, so as to realize gripping function. The actuating mechanism and operation mechanism of the photo gripping device in the invention are relatively simple, the size can be relatively small; and the gripping device provided by the invention has the advantages of being fast, precise, environmental-friendly and low in energy consumption and has the characteristics of not belonging to other driving modes such as remote manipulation and the like.
