直接扩频信号抑制正弦干扰效果，横坐标为信噪比，纵坐标为误码率(restrain of sinusoidal interference in ds_ss signal)

说明：  利用在 MATLAB Simulink 中的 SimMechanics 工具箱，在 Matlab 中搭建了机器人的机构模型，结合运动学数学模型，实现的机器人的运动模拟实验，并且通过末端执行器输入运动参数与输出运动参数的对比，验证了所建立的运动学模型的正确性。最后根据机构的实际限制条件，限制了两个主动臂的最大转动角度，结合正向运动学模型，得到了整个机器人末端执行器的极限运动位置坐标以及整个运动空间(Using the SimMechanics toolbox in MATLAB Simulink, the mechanism model of the robot is built in MATLAB. Combined with the kinematics mathematical model, the motion simulation experiment of the robot is realized. The correctness of the kinematics model is verified by comparing the input and output motion parameters of the end actuator. Finally, according to the actual constraints of the mechanism, the maximum rotation angle of the two active arms is limited. Combined with the forward kinematics model, the limit motion position coordinates and the whole motion space of the end effector of the whole robot are obtained)
