OMG, OMG, this is fantastic news! This is literally BIG news. Large robot ideas are flowing. Thanks again for the continued hard work and continued dedication.
Awesome Dj! You implementation this faster than I imagined. Khudos. Running 50 Robotis Dynamixel servos from D18 digital pin is awesome and leaves all those other pins open for the fun stuff.
Will there be tutorials on how to read the feedback from them? I imagine you'd control them with the ARC controls but, from the scripting side of it, would that use serial commands?
Amazingly fast response to implement the Dynamixel 's protocol into the EZ-B V4 flagship! Standing "O" for DJ and team. At 37$ in bulk and the high torque ratings etc.... this motor is a game changer for larger bots.....now if Dynamixel can downsize the package , even smaller bots can be happy! .....its getting exciting!
Edit They will all be controlled by the D5 pin. Only one signal pin is needed as they Dynamixels are chain-able.
But as you surmised, the power supply will quickly become the limiting factor.
One thing to note is that although Dynamixels can operate at a lower voltage (>6V) they do suffer from communication errors if the voltage is not in the 9 to 12VDC range. At least this is what we found for the AX-12A Dynamixels. I believe that most roboticists use an 11.1V LiPo to power them.
That's understandable. I've had tons of fun with the V3 since I got it. Thanks for all of the answers.

Looking at the line of servos they make will there be support for all their servos, or just the AX-12?
Edit: I see there are two types, the TTL version and the RS485.

How many dynamixels can it operate simultaneously?
PS I'm willing to send power from my 7.5v 46a power supply, which I'm sure will be necessary for my 24 DOF robot.
Hello @Zxen
ARC can control up to 99 Dynamixel servos.
