This is a 6 piece Bulk package of the MX-64T. 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-64AT Dynamixel Robot Servo Actuator is 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 TTL 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 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 MX 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.
The MX-64AT is a special version of the MX-64T with an aluminum 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-64AT is special order only and may take an additional 1-2 weeks to ship.
