XM430-W350-R servo: greater control of speed, trajectory, torque...

…and more! The new range of Dynamixel servos includes exciting new features for robotics enthusiasts:

  • Torque control: one of the major advantages of the XM430 range. It uses the current measurement to obtain a continuous flow of desired power.
  • PWM control: Dynamixel has opened its doors to PWM, which is excellent news for fans of radio-controlled vehicles because torque and output speed can be controlled more effectively on mobile robots.
  • Trajectory control: four types of trajectory are now possible thanks to the addition of acceleration and speed profiles. By controlling these two parameters, you can add an “effect” to your robot’s movement.
  • Current-based position control: position control and torque control can be combined to refine your robot’s movements.
  • Velocity and position controls: no surprise here, these were already a feature of the previous Robotis servo motors.
  • Possibility to plug the cable at the back, thus reducing any pinching or wearing risks.


As you can see, this new robot servo has what it takes to satisfy not only fans of radio-controlled wheeled vehicles but also fans of articulated robots with arms, hands and claws.

Dynamixel XM430 servo: a new-generation MX-28

Although the Dynamixel servos in the XM430 series prove slightly less powerful than the MX-106 servos, they are nonetheless an appreciable improvement on the MX-28 series.

They are more powerful and faster, and above all much more energy efficient at 40 mA compared with 100 mA for their predecessors. You will significantly increase your robot’s autonomy. It’s worth noting that the power supply equipment is the same for the XM430 as for the MX-28.

In terms of ergonomics, the XM430-W350-R servo is slightly more compact than the MX-28. The new design also offers a little plus, since the cables are connected directly to the motor and blocked by a cover, eliminating all risk of loose wires.

However, because the position of the tapped holes is not quite the same, you will need to get your hands on the metal structural components created especially by Robotis for their new creation. A variety of different sets are already available at our website!
