YuMi Python Interface

AutoLab, UC Berkeley

This package provides a python interface for control and communication with ABB's Yumi. Currently the interface is still undergoing development, so changes will occur to this repo. For best results please be on the newest commit of the master branch before installing and using.

Full documentation can be found at

UPDATE: As of commit f4be489 on June 18, 2017, yumipy depends on autolab_core, a renamed version of core. If this affects you (you have installed yumipy before June 18th, 2017), please do the following:

  • Pull the latest commit from core
  • Re-install using pip or following the instructions here
  • Pull the lastest commit from yumipy


Step 1: Install the alan YuMi python interface on the client computer that will communicate with the YuMi:

$ python develop

Step 2: Upload SERVER_LEFT.mod and SERVER_RIGHT.mod under src/alan/control/ to the left and right arms of YuMi through RobotStudio.


Simple example to import and use the YuMi interface (make sure the YuMi is in Auto mode and has the server running):

from yumipy import YuMiRobot
# starting the robot interface
y = YuMiRobot()
# getting the current pose of the right end effector
pose = y.right.get_pose()
# move right arm forward by 5cm using goto_pose
pose.translation[0] += 0.05
# move right arm back by 5cm using move delta

The control and RAPID server code is inspired by the open-abb-driver.
