此方案使用20路PWM控制伺服马达。其中18路PWM用于控制机器人的6根爪子，每根爪子具有3个伺服马达。调整PWM输出的占空比，我们可以控制伺服马达转动的角度，就能够操作机器人做出各种的动作。另外2路PWM用于控制机器人前方的夹持器，可以操作夹持器的张合。-This scheme USES 20 road PWM control servo motor.18 road PWM is used to control the robot s 6 claws, each paw has three servo motors.Adjust the PWM duty cycle of output, we can control the servo motor rotation Angle, will be able to do all kinds of operating robot.The other 2 road PWM is used to control the robot gripper ahead, can operate on the holder.
