摘要
介绍了一种安装在医疗机械手腕部的三维力传感器,该传感器采用电阻应变式电桥的测量方法,其弹性体为两个扁环式结构,在两个扁环的相应敏感部位分别粘贴三组应变计,解决了三维传感器体积大、刚度低等问题;其具有量程大、体积小、精度高、横向干扰小等特点,在实际应用中收到了良好的效果。
A three-dimension force sensor which is mounted on a medical robot hand is introduced. The sensor uses strain gauges on the elastomer to measure force, and this elastomer is made of two flat rings. Three groups of strain gauges are stuck on the elastomer. It solved the problem of large bulk and low rigidity. The sensor has the characteristics of high sensitivity, wild measure and small bulk. It works well in actually using.
