Dynamixel Robotis AX-18A Servo

Dynamixel Servo Robotis : AX-18A

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.
• AX-18A is a high performance version of the popular DYNAMIXEL AX-12A, and can be applied to robots that need more power.
• Applied a 4th metal gear to enhance endurance

For full details of the Robotis AX-18A dynamixel actuator, consult the dedicated sheet on the official website HERE.

Caution : 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.
