    This is a 6 piece Bulk package of the MX-28T. In this bulk pack, the servos are bare and do not come with the required servo horn, nor any additional cables, brackets, or hardware. The MX-28R Dynamixel Robot Servo Actuator is the newest generation of Robotis Dynamixel actuator; equipped with an onboard 32bit 72mhz Cortex M3, a contact-less magnetic encoder with 4x the resolution over the AX/RX series, and up to 3mpbs using the new RS-485 2.0 bus. Each servo has the ability to track its speed, temperature, shaft position, voltage, and load. As if this weren't enough, the newly implemented PID control algorithm used to maintain shaft position can be adjusted individually for each servo, allowing you to control the speed and strength of the motor's response. All MX Series servos use 12v nominal voltage, so other MX-R series Dynamixels can be mixed without having to worry about separate power supplies. All of the sensor management and position control is handled by the servo's built-in microcontroller. This distributed approach leaves your main controller free to perform other functions.

    Note: This servo is nearly identical to the MX-28T, the only difference being 4-pin RS-485 communication. If you do not have a specific preference, we recommend the MX-28T due to TTL communication being a simpler protocol.

    Every DYNAMIXEL servo is compatible with wide variety of horns, idlers and frames to help you easily build your robotic project. This hardware connects directly to your DYNAMIXEL servo, allowing you to mount it to your project or to other DYNAMIXEL servos. Some robots can be built almost completely from DYNAMIXEL servos and frames. You can see a full list of frames that are compatible with this servo on our DYNAMIXEL Compatibility Chart

    *Stall torque is the maximum instantaneous and static torque. ROBOTIS recommends that your robot or project uses 1/5 or less of the stall torque to create stable motions.
