ever wondered how robots perceive and
interact with their environment how they
navigate through a room pick up objects
or even respond to people the answer
lies in their sensors
sensors are the eyes ears and fingertips

they need to interact with the world
around them imagine a world with seven
types of primary sensors each one
playing a pivotal role each one with a
unique purpose first we have Vision

people and surroundings or take lidar
which uses lasers to measure distances
creating a three-dimensional map of the
environment this enables obstacle
detection and navigation much like a bat
uses echolocation next in line are
tactile and force sensors imagine a
pressure sensor as a robot's skin
detecting contact and pressure this
allows robots to handle delicate objects
and measure forces during their

force let's move on to proximity sensors
picture ultrasonic sensors that emit and
receive sound waves to gauge distances
and detect objects aiding in obstacle
avoidance and navigation or infrared
sensors which measure distances by
emitting and detecting infrared light a
useful tool for detecting nearby objects
don't forget about gyroscopes and
accelerometers a gyroscope is like a

just like a compass guiding a hiker last
but certainly not least our inertial

enable robots to make informed decisions
navigate and perform various tasks
without them robots would be blind deaf
and numb unable to interact with the
world around them so the next time you
see a robot expertly navigating a room
picking up an object or responding to a
person remember the sophisticated
sensors that make it all possible after
all in the world of Robotics perception
is everything
