Dynamixel AX-12W Servomotor

Dynamixel Servomotors

Dynamixel Range Overview

Key features of Dynamixel servomotors

Dynamixel servomotors are integrated actuators that include:

• A reducer
• A controller
• A driver

Dynamixel actuators have a unique identifier and communicate using digital packets.

The main features of the Dynamixel range are:

• A great position control accuracy (1024 divisions for AX, RX and EX models, 4096 for MX).
• Many feedback functions On the various physical variables of the servomotor (current position, speed, voltage, internal temperature, etc.).
• A alert based on internal temperature, torque, or supply voltage, which is activated when these values exceed defined limits. The Dynamixel servomotor provides feedback and can automatically correct the situation.
• ” Compliant guide ": controls the amount of spring force in position control.
• Stabilizer of. couple The torque can be stabilized in 1023 steps from the maximum torque to the free rotation state.
• Operation low current/high voltage Its efficiency is high because it operates at a higher voltage. The performance of your robotic system also improves because of its low current consumption.
• A Status LED Is used to display the status of Dynamixel.
• A mechanical group made easy by the many compatible mechanical parts.
• A easy wiring via 'daisy chain'

Dynamixel Actuator Programming

Servomotors must be connected to a controller ( . CM-700 , CM-5 , CM-510 or . CM-530 ) to be controlled. The programs are implemented with RoboPlus, very easily and without requiring much prior knowledge.

Newer controllers support the embedded C language, and a Software Development Kit-SDK is available for developing your own applications.

The Dynamixel AX-12W Servomotor

The Dynamixel AX-12 W servomotor is an entry-level servomotor from Dynamixel. Because of its low cost, it is widely used for all parts of your robots that require little precision and power.

The AX-12W servomotor is much faster than other Dynamixel servomotors in the same range. It is especially designed to drive the wheels of your mobile robots.
