The Dynamixel servomotors

Dynamixel Servomotors main features
  • All-around assembling structure: you can make robots of various forms as using different option frames.
  • Powerful feedback : It can read current position of Dynamixel or speed as well as various information such as internal temperature, supply voltage, target position.
  • Simple connection structure: Wiring is simple because it is linked by Daisy Chain.
  • Alarm function: When internal temperature, torque, supply voltage etc. escaped appointed range, it gives feedback about that situation. Also in such emergency situation, it flash LED or be Torque off.
  • Compliance configuration: It can configure the compliance to control the position.
  • Torque set up : Torque can be set up by 1023 steps from maximum Torque to free run state.
  • Low-electric current/high voltagedrive : Its efficiency is high because it runs by high voltage and it improves stability of robot system that is formed by Dynamixel because current consumption is low.
  • Status LED : It has LED that can check state of the Dynamixel.
  • Drive by network: Dynamixels have unique ID and are controlled by Packet communication on a bus. It supports network of TTL, RS 485, and CAN etc. according to model.

Dynamixel actuators are controlled by Packet communication

This video illustrates the capabilities and the existing application for Dynamixel servomotors:

Programming the Dynamixel servomotors

The servomotors have to be linked to a main controller (CM-700, CM-5, CM-510 or CM-530) to be commanded. The progams are made with RoboPlus, which allow really easy programmation, without much previous knowledge.

The most recent main controllers support embedded C and there is a SDK for you to developp your own applications.

The Dynamixel RX-24F HN05-N101 actuator

This actuator has a better torque than the other actuators of the RX range.
