Inventor: Yanlei Yu, Futao Cheng, Ruoyuan Yin, Yuanyuan Zhang

Applicant: Fudan University

Patent No.: ZL 200910053153.1

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.
