| 摘 要： | 针对可在受限环境中灵活运动的连续型同心管机器人传统正运动学方法计算时间较长,不利于机器人实时运行的问题,本文提出了基于机器人几何学的同心管机器人正运动学快速求解方法,能够在精度损失有限的情况下,提高正运动学模型的计算效率.先根据Cosserat杆模型对同心管机器人进行建模,再利用李代数理论建立了机器人空间位置和曲率的关系式,并结合提出的正运动学方法,对机器人进行了基于逆运动学的开环控制实验.最后通过3管机器人的仿真和实物实验验证了本文所提方法的快速性和有效性.

| Abstract: | This paper aims at the problem which traditional forward kinematics method of concentric tube robot takes
a long time to calculate and limits real time work, a fast solution method for the forward kinematics of the concentric
tube robot based on robot geometry is proposed in this paper, which can improve the calculation efficiency by losing just
a little of accuracy. The concentric tube robot is firstly modeled by the Cosserat theory. Then the relationship between
the concentric tube robot spatial position and the curvature is established by using the Lie algebra theory. Moreover, the
open loop control experiment based on inverse kinematics is carried out combined with the proposed forward kinematics
method. Finally, both simulation and physical experiment of the three-tube robot verify the rapidity and effectiveness of the
proposed method. |
