Dynamixel Sensor Module AX-S1

Price: $44.90
Availibility: In Stock
Item #: RO-902-0025-000


  Add more sensors to your Bioloid!

The AX-S1 is housed inside the same casing as the AX-12 BUT the AX-S1 doesn't contain a motor - it is simply a sensing module that can be placed on the same serial network. The AX-S1 consists of:

  • an IrDA receiver for robot-to-robot communication,
  • 3 IR reflection sensors (Left, Right & Front) that can be used to measure distance and luminosity,
  • a microphone, and
  • a piezo-electric sounder that can be used to play musical scales or simple a beeping sound.

This actuator is meant to be used with the Bioloid system.  To see all of our Bioloid products, follow this link.

For more information, including the full serial command set, download the AX-S1 manual.


Hardware Included
  When you purchase the AX-S1, not only are you getting a state-of-the-art actuator, you're also getting the hardware necessary to connect it to the rest of your project.
