This is a 6 piece Bulk package of the MX-28R. In this bulk pack, the servos are bare and do not come with the required servo horn, nor any additional cables, brackets, or hardware.
If you need this hardware, it must be purchased separately.
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.
The MX-28AR is a special version of the MX-28R with an aluminium front plate. This plate acts as a heat sink, allowing for better heat dissipation, allowing the servo to run cooler. The aluminum front plate has threaded holes, allowing for easier assembly as no nuts need to be seated on the front plate. The back plate will still require nuts.
NOTE: The MX-28AR is special order only and may take an additional 1-2 weeks to ship.
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
