Smart Arduino Digital Servo Shield for Dynamixel AX

IntroductionSome day,a guy want to make a robotic dog as a gift to his little son.He brought some digital servos, a microcontroller,Lipo batterys...Then he found it hard to drive these smart servos with Arduino processor! So we developed a driver board that can easily & quickly drive the digital servos such as AX-12 with Arduino directly! Just like using Arduino official servo library. With this smart arduino digital servo shield and Dynamixel AX series servos, It's quite easy for you to drive multi servos with daisy chain connection with an Arduino board such as Arduino Uno, and build your robotic dog, hexapod with powerful servos. This shield Integrates a half duplex circuit inside.That means the transmit wire from UART is connected to all of the AX-12 servos. If a command sending over the wire without servo ID, all of the servos will receive the command, and if the message contains the destination servo ID then only one servo, matching that ID number, will receive it. Because of
