Dynamixel Pro L54-60-S300-R servomotor

The Dynamixel servomotors

Presenting the Dynamixel range

Dynamixel servomotors from Robotis are digital servomotors than contain:

• a servomotor
• a gear train
• a microcontroller

The microcontroller receives communication packets and drives the servomotor accordingly.

The Dynamixel Pro range

Dynamixel Pro servomotors are more precise and more powerful than the Dynamixel servomotors. They are intended for a profesionnal use.

• A precise sensor feedback Dynamixel Pro servomotors have an absolute encoder with 4096 positions after the gear train and a incremental encoder with 1000 positions before the gear train.
• Several feedback readings available for the controller: current position, speed, voltage...
• Error detections : the servomotor stops by itself if it detects a wrong voltage (too high or too low), temperature issue, encoder error.
• PID control with adjustable parameters : manage the stiffness of your robot. You can define a maximal speed and acceleration to control the servomotor with a speed trapeze.
• All-around assembling structure: you can make robots of various forms as using different option frames.
• 3 programmable Status LED
• Easy Daisy-chainwiring

Warning, the most powerful servomotors from the Dynamixel Pro range (54 series) need to be powered with an external power source, in parallel

Programming the Dynamixel Pro servomotors

The Dynamixel Pro servomotors are controlled from a computer using a USB2DYNAMIXEL. They can be commanded from the RoboPlus software, mostly used for tests or to change the Ids of servomotors, in C/C++, Python, Matlab or ROS (Robot Operating System).
