Dynamixel MX-28R Servomotor

Dynamixel Servomotors: Optimal Performance for Advanced Robotics

Discover the range of Dynamixel Servomotors

**Dynamixel** servomotors are state-of-the-art actuators designed to facilitate precise control of your robotic projects. Each servomotor is an integrated unit that includes:

• A high-quality gearbox
• An efficient controller
• A reliable pilot

Each **Dynamixel** servomotor is uniquely identifiable and communicates through digital packets, making controlling your robots easier and more intuitive.

Key features of **Dynamixel** servomotors include:

• Highly accurate position control: 1024 divisions for AX, RX and EX models, and 4096 for MX models.
• Detailed feedback functionality on physical variables such as current position, speed, voltage, and internal temperature.
• Built-in warning system that monitors temperature, torque and voltage, triggering alarms to prevent malfunctions.
• Supporting "Conforming Guide": verification of elastic force in position control.
• Torque adjustment: ability to set torque in 1023 steps, from maximum to free rotation.
• Maximum energy efficiency through low current and high voltage operation.
• Status LEDs for easy visualization of the operating condition of **Dynamixel**.
• Simplified mechanical assembly due to compatibility with a large number of parts.
• Easy wiring via 'daisy chain' configuration.

Efficient Programming of Dynamixel Servomotors

To control servomotors, it is necessary to connect them to a compatible **controller**, such as the CM-700, CM-5, CM-510 or the CM-530. Programming is done intuitively using **RoboPlus**, requiring no advanced skills.

Newer models support the embedded C language, accompanied by an SDK for developing your own custom applications.

Dynamixel MX-28R Servomotor: Precision and Advanced Control

The **Dynamixel MX-28R** is an innovative servo motor that offers two versions: the **MX-28T** and the **MX-28R**. While the former uses an asynchronous half-duplex serial communication protocol, the latter uses the RS485 protocol for faster communication and a Multi Drop physical connection.

The MX series of **Dynamixel** stands out for its advanced features, including PID control, 360-degree positioning, and high communication speed.
