Dynamixel actuators have been used by every major university, research lab, military & government research lab, and robotic competition worldwide. The casing of each servo is built specifically with robotics in mind, providing easy to use mounting rails and a comprehensive bracket system available for building robotic limbs. TTL and RS-485 serial communication allows for daisy-chainable bus connections at up to 1-3mbps.

    The AX-12A servo actuator from Robotis is the standard for hobby robotics. The AX-12A robot servo has the ability to track its speed, temperature, shaft position, voltage, and load. As if this weren't enough, the control algorithm used to maintain shaft position on the ax-12 actuator can be adjusted individually for each servo, allowing you to control the speed and strength of the motor's response. All of the sensor management and position control is handled by the servo's built-in...

        The MX-12W from ROBOTIS is the Goldilocks of servos; everything about it is just right. It has the compact size of the AX-12A and AX-18A (and uses the same housing) yet has the electronics and control capabilities of the high performance MX servos like the MX-28T and MX-64T. This is the only servo at this size and cost, that is capable of true position control for multiple rotations. If you've ever tried to get more than one revolution out of your servo and been frustrated with losing your...

          The AX-12W servo actuator from Robotis is a wheeled variant of the popular AX-12A. Essentially this servo is an AX-12A with a lower gear ratio so that a much higher RPM can be achieved, making it ideal for use in 'Wheel Mode' as opposed to the traditional 'Joint Mode'. The AX-12W robot servo has the ability to track its temperature, voltage, and load. As if this weren't enough, the control algorithm used to maintain shaft position on the ax-12 actuator can be adjusted individually for each...

            The XL-320 servo from ROBOTIS is so small you might mistake it for an ordinary hobby servo, but you would be missing out! Despite its diminutive size, it is actually one of the newest models in the DYNAMIXEL robot servo line from ROBOTIS. Each XL-320 can produce up to 0.39 N-m (55 in-oz) of torque and rotate at 114 RPM in precisely controlled 0.29° increments. For its size (24 x 36 x 27 mm) and weight (16.7 g) there is no other servo that can compete with the XL-320 in performance and...
