Python package for FANUC industrial robots

fanucpy: Python package for FANUC industrial robots

IMPORTANT

The funding for this project officially ended on September 1, 2023. I am seeking external funding to keep this package alive and to develop packages such as abbpy, kukapy, etc. Please help me with your comments and use cases to understand better your needs. This is my calendar link for arranging a quick video call: https://calendar.app.google/GRfs1Q61QbQSMtAD8.

Software contents

The package consists of two parts:

1. Robot interface code written in Python programming language
2. FANUC robot controller driver (tested with R-30iB Mate Plus Controller) written in KAREL and FANUC teach pendant languages

The communication protocol between the Python package and the FANUC robot controller is depicted below:

Python package installation

pip install -U fanucpy

Driver installation

Follow these steps to install FANUC driver.

Usage

Connect to a robot:

from fanucpy import Robot

robot = Robot(
    robot_model="Fanuc",
    host="192.168.1.100",
    port=18735,
    ee_DO_type="RDO",
    ee_DO_num=7,
)

robot.connect()

Moving

# move in joint space
robot.move(
    "joint",
    vals=[19.0, 66.0, -33.0, 18.0, -30.0, -33.0],
    velocity=100,
    acceleration=100,
    cnt_val=0,
    linear=False
)

# move in cartesian space
robot.move(
    "pose",
    vals=[0.0, -28.0, -35.0, 0.0, -55.0, 0.0],
    velocity=50,
    acceleration=50,
    cnt_val=0,
    linear=False
)

Opening/closing gripper

# open gripper
robot.gripper(True)

# close gripper
robot.gripper(False)

Querying robot state

# get robot state
print(f"Current pose: {robot.get_curpos()}")
print(f"Current joints: {robot.get_curjpos()}")
print(f"Instantaneous power: {robot.get_ins_power()}")
print(f"Get gripper state: {robot.get_rdo(7)}")

Calling external program

robot.call_prog(prog_name)

Get/Set RDO

robot.get_rdo(rdo_num=7)
robot.set_rdo(rdo_num=7, value=True)

Get/Set DOUT

robot.get_rdo(dout_num=1)
robot.set_rdo(dout_num=1, value=True)

RobotApp

We introduce an experimental feature: Robot Apps. This class facilitates modularity and plug-and-produce functionality. Check the following example apps:

1. Pick and Place App
2. Aruco Tracking App
3. FANUC ChatGPT
