Time
Learning
objectives
In
this
class,
you
will
obtain
key
information
on
RoboBees
from
the
video;
design
a
robot
and
explain
how
this
robot
might
be
used.
What
does
the
picture
show
us?
Warming
up
A
robot
is
raising
up
a
little
boy
who
is
looking
into
the
universe.
However,
in
the
not-too-distant
future,
we
will
be
living
in
smart
homes
that
will
lock
the
door
for
us
when
we
are
away
and
remember
to
switch
off
the
TV
when
we
forget.
These
smart
homes
will
keep
us
secure,
save
us
energy,
and
provide
a
more
comfortable
environment
to
live
in.

about
the

AFTER

A
large
robot
often
takes
up
too
much
space
and
has
difficulty
in
moving.
Small
robots
working
together
can
easily
enter
a
small

and
move
around.

AFTER

WATCH
They
might
be
useful
in
rescue
after
a
disaster.
For
example,
if
a
building
was
blown
down
in
a
storm,
they
could
fly
into
the
wreckage
and
check
for
survivors.

spider
could
be
useful
