Issue:
I have been using Dynamixel Servos MX-28AT(2.0) with a U2D2 controller powered by a Robotis SMPS and Power hub board.
However, I want some information regarding U2D2 and Power Hub board. I want to obtain an output signal from the U2D2 or Power Hub board indicating that the servo motors have started moving. This signal should be in voltage, and it will be used as a trigger to integrate a camera with time synchronicity.
I have checked using a Digital Multi Metre; when all the connections are done in diasy chain the voltage in the Dynamixel terminals is always 12V, irrespective of the data transfer. So I cannot exactly say from this voltage that the servo has started moving.
Kindly suggest a solution in this direction for getting a start signal output.
DYNAMIXEL Servo:
MX-28AT(2.0) - 3 servos
DYNAMIXEL Controller:
U2D2 with PowerHub Board
Software Interface:
Matlab
