What is Human following Robot | Arduino robot
Here after the name all the persons are thinking about the Robot
what is it? and what does the meaning of this title? will it really follow the
humans? No this is basically the following robot that can follow anything.
This Arduino robot having
a sensor that can detect any object near
it and can follow this object. if you come in front of the robot it will start
following you. this robot consists ultrasonic sensor and IR sensor which help to follow the
object. this is similar to the obstacle avoiding robot only
but opposite in the working.
How does it work?
To know the working of this awesome human following robot read
this paragraph.
when you come near to the robot starts to follow you. there are
4 wheels in the robot. and 4 motors attached to the chassis. now there are
three sensors on the robot one is an ultrasonic
sensor and two IR sensor which
arranges like two sensors left and right to the ultrasonic sensor. and when you
put your hand near to the ultrasonic sensor the robot will start forward.
If you turn your hand to the left side the Arduino robot moves
on the left side, and if you put your hand in the right the robot will move in
the right direction. so, how the whole system works we will talk about this.
when you put your hand in from of the ultrasonic sensor then the
sensor detects you and sends this information to the Arduino. there is some
distance prefix in the Arduino so if your hand is away from the sensor it will
not read that. and if your hand is near to the sensor it will read it.
Now Arduino knows that there is something in front of the sensor
and Arduino
send some instruction to the motor driver and motor driver
trigger the motors. and the Arduino robot starts to move forward we need to run
all motor forward.
Now, what about the sensors. Ir
sensor works on infrared light which can also detect the object
near to it. so there is two IR sensor one is at the left side of ultrasonic
sensor and other is at the right side of the ultrasonic sensor. when anything
comes near to the left sensor Arduino got the information that there is
something is near to the left sensors and according to the code, the robot will
turn to the left. and the same process for the right sensor. so this is how
the human following
robot works.
