Dynamixel Servomotor AX-12A

Servomotor Dynamixel Robotis : Unit or set of 6

Dynamixel AX-12+ actuators are among the most efficient actuators on the market. The AX-12+ servomotors are controlled by a 1Mbaud serial link and can be connected to each other to create servomotor chains (Daisy-Chain). Up to 254 servomotors can be connected in series to the Dual-POB with a single cable.

These motors have a resolution of 1024 steps and a speed that can also be adjusted to 1024 steps. In reading, it is possible to know their current position, speed, torque, etc. Thus, it is possible to detect contact with an obstacle, wheel slippage or the presence of a slope without additional sensors.

Choose on this product sheet at the time of your order if you want an AX-12A dynamixel servomotor by unit or in a pack of 6.

Dynamixel Servo Robotis : AX-12A

DYNAMIXEL is a robot exclusive smart actuator with fully integrated DC Motor + Reduction Gearhead + Controller + Driver + Network in one DC servo module.

  • Dynamixel AX-series are used in ROBOTIS STEM, Premium, and GP. 
  • You can easily create various types of robots such as humanoid, 4 legged and 6 legged robot with the AX-series.
  • It can also be used as a wheel so that you can create a robot with a combination of wheel type and joint type in a single module.
  • By using a variety of high-strength engineering plastic option frames or by printing frames using a 3D printer, you can produce any type of robot at a low cost.

For full details of the Robotis AX-12A dynamixel actuator, consult the dedicated sheet on the official website HERE.

Warning : The set of 6 servomotors ensures a unit price lower than the purchase of a single model but does not include the accessories normally provided.
