Abstract
Vision-based
tactile
sensors
capture
visual
information
from
contact
surfaces
to
perceive
signals.
In

years,
these
have
been
widely
used
in
robotic
systems
enhance
their
perception
capabilities.
To
meet
the
demands
of
various
application
scenarios,
numerous

designs
for
developed.
This
paper
reviews

we
categorize
existing
into
three
main
types:
based
marked
features,
coating
geometric
vision-tactile
modality
fusion
For
each
type,
delve
core
technical
challenges,
solutions,
corresponding
strategies.
By
summarizing

this
aims
provide
researchers
with
a
comprehensive
