摘 要:Light-responsive liquid crystal elastomer actuators(LCEAs) enables novel remote-controlled soft robot actuation,bringing new possibilities to the application of soft ***,these actuators have complicated dynamic characteristics,and a dynamic model that can describe the deformation process of LCEAs is needed to predict and control their *** on the above consideration,this paper proposes a model to describe the dynamic deformation process of light-responsive *** proposed model consists of two parts:a dynamic temperature model and a dynamic deformation *** order to verify the proposed model,we establish a light-responsive LCEA experimental platform and perform LCEA deformation *** parameters of the model are identified by the nonlinear least squares *** experimental results show that the proposed model can characterize the dynamic deformation process of LCEAs with precision.
