Our mission is to provide robotics as production services, making it intuitive and universally accessible for
everyone. With this mission in mind, we redefined robotics with cost-efficient and the most easy-to-use
robot for industrial automation –the Franka Production 3 robot.
Our human-centered design in the technology with seven axes is tactile and safety certified, making it
available for all kinds of use cases in the industry.
Our AI-enabled collective learning platform enables scalable software solutions and reduces learning time
and resources to a minimum with intuitive and simple programming.
We provide an inclusive robotics platform with hardware and software –operating within one ecosystem.
Designed, developed, manufactured, and serviced in Germany.
Introducing Franka World –a digital robotics platform
After redefining robotics and establishing a community, we launched a novel digital robotics platform to
interconnect the digital world with the physical world.
Franka World allows community interaction between researchers, partners, customers, developers,
suppliers, and robots. In addition, all users can easily gain integrated access to products and services and
manage their entire robot fleets, independent of their physical location.
We strive for a world where everyone can use a robot, and we can reach that by connecting the world. We
treasure our community of robotics professionals, academics, and enthusiasts, from whom we learn every
single day.
As members of the community ourselves, we commit to supporting each other and thriving together.
Franka Emika –a certified robotics platform with tactile intelligence.

Fingertips The fingertips can easily be changed and adapted to the objects to be grasped (e.g.
using 3D-printed fingertips).
Fingers The fingers can also be mounted in a rotated orientation in order to increase the span
length of the gripper.
Plug The plug is simply plugged into the X6 end effector connector port on the grip of the
Arm.
Interface/flange The interface/flange of Franka Hand is designed according to DIN ISO 9409-1-A50.

4.2 Notice of Liability
Franka Hand has been developed according to the relevant quality standards. A hazard and risk assessment
according to EN ISO 12100 has been carried out through the course of development and is the basis for
Franka Hand and this manual.
The present document includes assembly instructions for compatible Franka Emika robots as partly
completed machinery. It contains descriptions of the conditions which must be met with a view to correct
incorporation in the final machinery, so as not to compromise safety and health (e.g. Annex I of Machinery
Directive 2006/42/EC).
4.3 Intended Use
Use the Franka Hand only in connection with compatible Franka Emika robot systems and the associated
intended use. The Franka Hand can be used for research and industrial use.
The end effector may be applied only in the ambient and operating conditions described in this document
for the tasks of e.g., testing and inspection, Franka Handling, or mounting.
Franka Hand may only be used in sound technical condition, for its intended purpose and within the
technical specifications and operating conditions, with awareness of safety and possible dangers.
The present Franka Hand end effector is intended exclusively for use as described in this manual.
For the normal and extended working conditions under which the Franka Hand should operate, see
Technical Specifications.
4.4 Misuse
Misuse of the Franka Hand voids the manufacturer's warranty and liability. Any application different to the
intended purpose is considered a misuse and is not permissible.
WARNING
Misuse may lead to danger to life and limb, impairments, damage to the robot, and other material
assets. The manufacturer is not liable for damages caused by misuse.
Misuse is any use that deviates from the warnings, notices, and instructions in this manual, in particular, but
not limited to, the following uses:
•Transportation of people and animals
•Transportation without original packaging
•Use in potentially explosive areas
•Use below ground
•Use in Franka Handling of radioactive objects
•Use outdoors
•Use as a medical product
•Use in the vicinity of children
•Franka Handling of liquids
•Use outside of the specified operating limits
Modifications to the Franka Hand that are not explicitly permitted by Franka Emika are not allowed and will
lead to loss of warranty and liability claims. Not permitted modifications include, but are not limited to, the
following:
•Any adaption of the mechanical structure
•Varnishing

SAFETY
220010/1.2/EN Franka Emika GmbH © 9
•Enwrapping the robotic structure
It is prohibited to open the Franka Hand enclosure and other equipment.
Franka Emika is not liable for damages caused by mounted, grasped or lost equipment or damages caused
by misuse.
4.5 General Possible Dangers and Safety Measures when
Working with Robots
An extensive but not definitive list of dangers that generally may be presented by a robot system can be
found under EN ISO 10218-1:2011 ANNEX A.
Before putting the Franka Hand into use with a robot, an application-specific risk assessment (e.g.,
according to EN ISO 12100 and/or EN ISO 10218-2) must be performed by the integrator.
SEEPO (“Safe End Effector Power Off” safety function) may be configured in the robot accordingly. For
more information, see chapter Safety Settings and Watchman in the relevant Franka Production product
manual.
