What was the initial reception of
maxon’s motors for exoskeletons?Ineichen: Last year, we released our
Exoskeleton Joint Actuator. A lot of
universities used it for prototypes, and
they liked it very much.
Based on their experience and
feedback, we are able to provide more
customized drives.How is exoskeleton technology
changing? We already know that
battery weight and endurance are
issues.Ineichen: Based on what we’ve learned
from the first users, exoskeleton
developers need to continue trying to
reduce the weight and to make it more
dynamic. Most exoskeletons do not have
the range of motion of the human body,
but that is improving.What else should exoskeleton
designers be aware of?Ineichen: During the development stage,
we thought that backlash would be
important and then discovered that was
not the case. This allowed us to work on
a simpler design and put more effort into
dynamic motion controls.
At maxon, we understand that
customization is very important during
the design concept. At our newly built
manufacturing facility in the U.S., maxon
engineering services assist with project
design.
We’re also working with universities
participating in Cybathlon 2020, a
competition for people with physical
disabilities using assistive technologies.
maxon is a key sponsor of the event
and is supporting teams with our drive
systems, as well as our expertise in drive
technology. (continues on page 65)New Zealand-
