by hand and without any resistance so that waypoints or paths
can be taught quickly and precisely. (Image: Festo SE & Co. KG)

articulated arm, a handheld module, and software.

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. (Image: Festo SE & Co. KG)

CLEAR EPOXY
CURES AT 80 °C
Master Bond EP4CL-80
is a one part, exceptionally
low viscosity
epoxy for bonding and sealing. This free-flowing
system cures readily at 80 °C to 85 °C in one hour
or 5-10 minutes at 100 °C. It is not premixed and
frozen and has an unlimited working life at room
temperature. EP4CL-80 possesses excellent dimensional
stability and low shrinkage upon curing.

smooth and rounded at the edges so
that humans collaborating with the
pneumatic cobot cannot be hurt.
Pneumatic direct drives and light
weight reduce contact energy. Pressure
regulators in the articulated joints will
allow the robot to recognize when it is
being touched and respond with appropriate
safety functionality.
Collaborative robots originally were
developed to help workers perform assembly
tasks; today, they have many more
applications. One potential application
for a pneumatic cobot will be in 3D
printers, where units remove powder residue
by blowing it off and then detach
the finished component. In logistics operations,
the cobot can apply labels to
packages of different heights using its
fine sensor technology without pressing
in or damaging the surface.

ISO/TS 15066 and the need to specify
each individual application according to
safety aspects are the limiting factors so
far in terms of barriers to a broader
adoption of cobots. The inherent safety
features of pneumatic cobots should
help lower those barriers and speed
adoption.
Robots have always been electrically
driven. Shortly there will be pneumatically
powered units. What other new, different,
and exciting features will design
engineers invent to advance human/
machine collaboration? Adaptive gripping
is one area of great interest. Time
will tell.
