    Question(s) AX12A power consumption

    Does anyone know or know how to determine the power draw for AX12A servos that aren't being driven? I.e. set with torqueEnabled = false. We're powering the Master arm with 4 AX12As and trying to...

    Question(s) Re: Attaching hobby servos stops AX-12A from working

    Thanks for all the help in looking into this. I think the problem I faced just running the attach code and failed servo calls were due to a bad board. Using the same code and wiring on another (3rd...

    Question(s) Re: Attaching hobby servos stops AX-12A from working

    It seems like it's my Arbotix-M. As I said it worked on another board when I only had the AX12As and servos installed. I thought it may have been all the wiring on the first board that was causing...

    Question(s) Re: Attaching hobby servos stops AX-12A from working

    Do you think there might be a capacity problem of having 7 AX12As driven in a slave arm, 9 pushbuttons, 1 toggle, 1 potentiometer and 4 AX12As as a master arm be too much for the Arbotix-M?

    Question(s) Re: Attaching hobby servos stops AX-12A from working

    So it doesn't appear to be software related. I used another Arbotix-M and just plugged in the dynamixel serial cable and the servo (along with the 5V jumper) and it can read all the AX12A servos...

    Thanks for your reply and help Kurt.

    Yes - Arbotix-M and Arduino 1.6.10

    It works (i.e. AX12A servos can be called without error when the servo is plugged in but the servo attach function is not...

    Re: Shoulder / Elbow paired servo calibration

    Thanks for the quick response and suggestions. I captured the position values of the tandem servos and the actual positions were pretty different from the 1023 - x theoretical position value. ...

    Shoulder / Elbow paired servo calibration

    Hi,
    For the shoulder and elbow joints, the PhantomX Reactor Arm has 2 mirrored servos that work together to share the load. In trying to create a Master / Slave control, I read the position of the...
