MX28T + horn

The MX-28T 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 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 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 AX & 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.
