joints through meaning in Chinese

动关节

The actuator is set in the joint axis in traditional arm , this increased the arm inertia , the dynamical property of robot is poor . if put the actuator on base , and transfer the movement and force to joints through tendons ( cable ) , the weight and size of arm can be decreased . furthermore , consider from bionics , tendon ( cable ) - driven is more closed to the movement and force transfer mode of lives using muscles
腱(柔索)驱动机构具有广泛的应用前景，本文对其在其他领域的研究和应用情况进行了叙述，以在风洞中的应用为例，给出了一类腱(柔索)驱动机构的构型设计，创造性地运用正交补的方法分析了其工作空间，并研究了柔索受力、刚度条件及误差补偿的方法，为柔索驱动并联机构在风洞中的应用打下了基础。
