我们提出了一个并联机器人机构和本构关系,管理其组成的软执行器的变形。我们的最终目标是实时运动校正患者的头部偏离目标姿势,其中软致动器控制患者的颅骨区域在治疗机上的位置。我们描述的机制,推导出的应力-应变本构关系的个别致动器和逆运动学,规定一个给定的变形,然后提出的模拟结果,验证我们的数学公式。我们的研究结果表明,我们的径向对称位移公式下的有限弹性变形框架一致的变形。
We present a parallel robot mechanism and the constitutive laws that govern the deformation of its constituent soft actuators. Our ultimate goal is the real-time motion-correction of a patient’s head deviation from a target pose where the soft actuators control the position of the patient’s cranial region on a treatment machine. We describe the mechanism, derive the stress-strain constitutive laws for the individual actuators and the inverse kinematics that prescribes a given deformation, and then present simulation results that validate our mathematical formulation. Our results demonstrate deformations consistent with our radially symmetric displacement formulation under a finite elastic deformation framework.
