Easy to Operate and Flexible to Use
A pneumatic cobot will consist of the articulated arm, a handheld
module, and software. To be successful the software must
be intuitive. Pneumatic drives enable the robot arm to be easily
guided by hand and without any resistance so that waypoints or
paths can be taught quickly and precisely. The future of cobots
demands, especially for smaller companies, that commissioning
and programming should be accomplished in less than an hour.
Why so short a time? Because these units must be easy to use by
the typical worker. This quality lessens resistance to technology.
Prior knowledge of robotics must not be necessary.
Especially for small- and medium-sized companies, cobots are
only attractive if they can practically and quickly assume a
new task, not just permanently perform the
same job. The pneumatic
cobot
will meet this requirement as it doesn't require an additional control
cabinet that is difficult to connect and cumbersome to move.
A compact controller will be integrated in the cobot's base, increasing
its flexibility. Simple connections also allow it to be used
ad hoc and without long changeover times. Common bus standards
will enable fast connection to higher-order controllers.
Thanks to state-of-the-art, lightweight construction methods,
the weight of these units should be under 20 kg, which will facilitate
quick and easy movement to other locations.
Working Safer and Faster
A pneumatic cobot should be able to function similarly to a
human arm and be perceived as a helping third hand when
working with a team member. It will move like a real colleague
- within a manageable radius. Thanks to the flexibility of
pneumatic drives, the cobot acts sensitively - at a speed appropriate
to the situation and with fluid, harmonious movements.
Designers will ensure it is as soft to the touch as human contact.
The surfaces of the pneumatic cobot will be

" A cobot based on
pneumatics owes many
of its advantages, such
as sensitivity, weight,
and cost value, to the
benefits of compressed air
technology. "
