Description
In this video, Chad Coarsey (Director of Operations, The Bionic Glove Project) and Wen-Yu (Marty) Cheng (Undergraduate Researcher, FAU BioRobotics Lab) demonstrate a new flexible arm design that allows for greater freedom of movement.

Right
and
grab,
and
then
you
have
to
do
a
forceful
contraction
and
hold
it
to
hold
it,
whereas
now
I'm
able
to
kind
of
come
in
and
guy
right
here
is
a
socket
for
a
be
Bionic
hand.
So
we
did
make
the
inside
ring,
but
we
custom
fit
a
portion
of
the
3d
printed
part
to
fit
the
ring.
And
if
it's
together
here
as
well,
yes,
so.
D
So
we're
able
to
fit
multiple
different
devices
into
it,
which
is
the
idea
when
you're
using
this
in
a
lab
for
testing,
to
understand
the
ability
of
my
electric
sensors
to
pick
up
when
you're
moving,
because
if
you're
have
a
sensor
and
it's
stretching
or
being
deformed
over
a
surface,
you're
gonna
get
a
decrease
in
signor
perturbation
of
signals.
So
the
idea
that
Marty
is
mentioning
is
that,
because
of
the
rotation
of
the
arm,
it's
limited
at
the
bottom,
where
the
electrodes
are
you
don't
get
that
displacement
as
much?
D
You
know,
cross
talking
with
muscle
groups,
you're
getting
multiple
degrees
of
freedom
instead
of
just
a
single
open
and
closed.
But
you
can
do
you
know
pinch,
you
can
do
pibil.
You
could
do
like
full
grabs,
for
example,
so
it
just
allows
a
couple
of
different
degrees
of
freedom,
and
then
you
want
talked
about
the
co
contractions.
D
Is
how
can
we
make
degrees
of
freedom
that
don't
exist
right?
How
can
we
do
that?
So
one
of
Marty's
works
that
he
is
working
on.
He
just
doesn't
think
it's
okay,
so
one
of
the
things
he
works
on,
though,
is
we're
buying
that
those
degrees
of
freedom
and
providing
that
and
so
part
of
the
co
contracture
means
I
would
flex
my
top
and
my
bottom
muscles,
and
that
would
tell
intuitively
a
signal
to
change
a
command.

This
is
your
own
up
right,
your
old
now,
your
pinkie
aren't
going
right.
This
is
your
radius.
This
is
your
internal
thumb
bass
drum
right,
so
this
is
stationary
and
when
you
pivot
your
arm,
your
radius
actually
pivots
around
the
own
up.
So
if
you
see
here,
the
material
is
kind
of
conformed
linearly
to
the
old
are,
but
here
it's
kind
of
actually
tracing
a
muscle
group
that
goes
across
your
forearm,
which
is
responsible
for
those
movements.
D
D
D
Another
point
too:
so
as
a
wrist,
this
articulation
amputee.
One
thing
that
we
have
to
consider
is
normally
now
you're
putting
something
on
top
of
a
distal
appendage.
There
you
may
get
some,
you
know
symmetry,
but
their
chances
are
you're,
gonna
put
a
handle.
So
in
terms
of
you
know,
you
know
tweaks
and
I
think
that's.

This
is
the
first
prototype
you
guys
might
have
seen
last
year
or
working
on
a
second
prototype
dependent,
allow
the
leg
to
fully
circum
to
kind
of
fit
around
the
whole
entire
arm
versus
having
a
single
bolt,
because
one
issue
that
we
found
is,
if
you
over
stimulate
these
things
will
blow
up
as
their
silicone
and
they
were
pop.
So
we
cannot
have
that
happening
so
Marty
its
project,
the
smallest,
where
the
refitting
it
I
think
you're.
