Item #: KIT-AX-18A
Availability: In Stock
Price: $169.95


    The AX-18A Starter Kit is a perfect starting point for any serious project using the Robotis DYNAMIXEL actuators. It contains everything needed to interface AX-18A series servos with the U2D2, including power/hub breakouts, and a cable pack. This kit provides access to the DYNAMIXEL API, Roboplus DYNAMIXEL Wizard for firmware updates, recovery, and an easy to use UI to configure & test servo attributes.

    Kit Includes:


    • Configure & ID DYNAMIXEL Servos
    • Set Baudrates
    • Update Firmware
    • DYNAMIXEL Recovery Options
    • Interface with the DYNAMIXEL API (C, C++, MATLAB, Labview, Etc)
    • Power Supply & Interface included
    • 6 Port Hub + 10-pack of cables

    The AX-18A servo actuator from Robotis is the next step up from the hugly popular AX-12A Servo, offering nearly twice the speed and 15% more torque! The AX-18A robot servo retains the formfactor and all of the same features of its predecessor: 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-18A 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 microcontroller. This distributed approach leaves your main controller free to perform other functions. Note: The AX-18A does NOT include mounting and bracket hardware, this is sold separately.
