The ACTION instruction is useful when multiple Dynamixels needs to move
simultaneously. When controlling multiple units, slight time delays occur
between the 1
st
unit to receive an instruction and the last one. The Dynamixel
approach fixes this problem through the use of the ACTION instruction.
Broadcasting When sending ACTION instructions to move more than two Dynamixel units, the
Broadcast ID (0XFE) should be utilised.
