pydobot2 0.1.0

Python library for Dobot Magician

Python library for Dobot Magician

Based on Communication Protocol V1.1.4 (latest version here)

Installation

Install driver from https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers.

pip install pydobot

Example

from serial.tools import list_ports

from pydobot import Dobot

port = list_ports.comports()[0].device
device = Dobot(port=port)

pose = device.get_pose()
print(pose)
position = pose.position

device.move_to(position.x + 20, position.y, position.z, position.r, wait=False)
device.move_to(position.x, position.y, position.z, position.r, wait=True)  # we wait until this movement is done before continuing

device.close()

Methods

• Dobot(port, verbose=False) Creates an instance of dobot connected to given serial port.

  • port: string with name of serial port to connect
  • verbose: bool will print to console all serial comms

• .pose() Returns the current pose of dobot, as a tuple (x, y, z, r, j1, j2, j3, j4)

  • x: float current x cartesian coordinate
  • y: float current y cartesian coordinate
  • z: float current z cartesian coordinate
  • r: float current effector rotation
  • j1: float current joint 1 angle
  • j2: float current joint 2 angle
  • j3: float current joint 3 angle
  • j4: float current joint 4 angle

• .move_to(x, y, z, r, wait=False) queues a translation in dobot to given coordinates

  • x: float x cartesian coordinate to move
  • y: float y cartesian coordinate to move
  • z: float z cartesian coordinate to move
  • r: float r effector rotation
  • wait: bool waits until command has been executed to return to process

• .speed(velocity, acceleration) changes velocity and acceleration at which the dobot moves to future coordinates

  • velocity: float desired translation velocity
  • acceleration: float desired translation acceleration

• .suck(enable)

  • enable: bool enables/disables suction

• .grip(enable)

  • enable: bool enables/disables gripper
