Rethink Robotics Baxter Bedienungsanleitung
user guide
for intera 3.2 software
Welcome!
Thank you for purchasing Baxter, the world's first collaborative robot for manufacturing.
This user guide is designed to provide you with an overview of the robot's features, help support
you through the setup process, instruct you on training Baxter for tasks, and outline some basic
troubleshooting measures should you need them.
The latest and most detailed information is available on our Intera MFG Wiki page at:

Safety Statement
Complying with ISO 10218-2 requires performing a risk assessment of each application to
determine the needed safety performance and safeguarding. ANSI RIA R15.06-2012 is a U.S.-
national adoption of ISO 10218-1 & 2.
Users should exercise caution while training Baxter and practicing its motions. The risk of injury
is increased when using custom end-effectors, off-vertical motions, and potentially hazardous
work pieces.
Rethink Robotics recommends the use of safety glasses when interacting with Baxter, as with
other equipment used in industrial environments.
For additional information, reference Baxter’s Safety Documentation: http://www.rethinkrobot-
ics.com/resources/safety/
Baxter’s maximum transit speed is now controlled to 2 meters per second. (2 m/s).

Quick Start
Quick Start
Performing a Pick and Place in Just a Few Minutes
Follow the steps in this section to get up and running with Baxter quickly. The bulk of this User
Guide explains Baxter in more detail its parts, terminology, how to perform various tasks, create
paths, etc., but to get a very basic idea of how to operate Baxter, start here.
NOTE: For Baxter to perform properly, it should be calibrated (see “Calibrating the Arms” on
page 138), and its grippers attached (per the instructions in the gripper kit) and configured (see
“Appendix A: Configuring Grippers” on page 143) before you train a Pick and Place task. Otherwise,
Baxter’s arm may pull or miss Picks when performing tasks.
Power On Baxter
To turn Baxter on, press and release the white power button on the lower left back of the robot (See
“Back View” on page 14 for the location.)
IMPORTANT: Do not
hold the power button down when powering on. It could damage the robot.
The lights on the head turn on, and the display shows a neutral face.

Quick Start
1. Move the Arm
Grab anywhere along Baxter’s arm and push and pull on it slightly to feel its resistance. Now, grab
the indented portion of the
training cuff,
the part between Baxter’s wrist and grippers, and squeeze
it just above the buttons on either side. Baxter is now in “Zero G” mode and you can now move the
arm easily.
Release the training cuff and the arm becomes (semi-) rigid again. Note that the arm stays in the
location and orientation it was in when you stopped squeezing the training cuff. The location and
orientation of the arm (its shoulder, elbow, wrist, and so on) is called its
pose
.
THE NAVIGATOR
On both of Baxter’s arms, and on either side of Baxter’s torso, is the Navigator, a set of buttons and
a knob you use to make selections on Baxter. The selections you make on the Navigator are shown
on Baxter’s display.

Quick Start
2. Create a New Task
The work you train Baxter to perform is called a
task
. A task can be very simple, like the pick and
place you’re about to create, or much more complicated, involving both of Baxter’s arms moving in
a coordinated fashion to and from multiple pick and place locations, holding a variety of poses, and
sending and receiving signals from other machines and devices.
