Python Dynamixel

Python package to use Dynamixel servos through a serial interface (unofficial, easier SDK).

Documentation

The full documentation can be read at https://pydxl.readthedocs.io.

Example code:

import time

from pydxl import Mx28, SerialLink

link = SerialLink(
    device="/dev/ttyUSB0", baudrate=1_000_000, protocol_version=1.0
)

servo = Mx28(identifier=1, serial_link=link)
servo.ping()
servo.led = True

servo.torque_enable = True
servo.goal_position = 2000
print(servo.goal_position)
time.sleep(3)
servo.goal_position = 1500
time.sleep(3)
servo.torque_enable = False

link.close()

Features

• Use protocol 1.0 through a serial link, known to work with:
  • U2D2
  • USB2Dynamixel
  • DARwIn-OP (after having installed a more recent Python, tested with Python 3.7.2)
• Support servos:
  • MX-28
• TODO: implement protocol 2.0
• TODO: add more servo types
