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.

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 EX-106+ actuator

The actuator EX-106 + is the actuator need for your robots where some power is needed, more than speed. The EX-106 + distinguishes itself by a high torque capacity compared to other actuators of the Dynamixel range. The MX-106R and MX-106T are the adaptations of the EX-106+ servomotor for the MX range.
