Abstract

In this study a cable actuated soft gripper is used to analyze the effects of finger material properties on grasping forces. The gripper design and the fabrication of soft fingers using materials of varying elastic moduli are presented. A model to predict the holding force of each gripper configuration is introduced and predictions are compared to results from grasping experiments. The experiments show a decrease in grasping force with increasing finger stiffness when normalized for the cable tension as predicted by the model.

材料性能对软夹持器抓取力的影响
本研究采用一种缆索驱动的软抓取器,分析了手指材料特性对抓取力的影响。介绍了变弹性模量材料夹持器的设计和软指的制作方法。介绍了一种预测各种夹持器构型夹持力的模型,并将预测结果与夹持实验结果进行了比较。实验表明,将模型预测的索张力归一化后,抓握力随手指刚度的增加而减小。
