Introduction: Follow Me Robot OR Object Follower Using Arduino

Hello I'm Ganesh.. As name said the Robot follows any Object it may be Human or Anything. I made this Robot using User friendly Microcontroller that is Arduino uno, You can use any other version of arduino also. I also have a youtube channel where you can see the process of making it in the video (link below). so let us get started

My youtube channel

Step 1: Collect Required Components

1) Arduino uno

2) L293D Motor driver

3) Gear Motors and Wheels (4x)

5) Servo Motor

6) Ultrasonic Sensor HC-SR04

7) Infrared Sensor (2x)

8) Battery

9) Male and Female Jumper wire

10) Acrylic Sheet or Wooden Cardboard

Step 2: Make the Base or Chassis of Robot and Mount the Motors

Make the chassis using acrylic sheet or Wooden CardBoard (if you have readymade one then no problem you can skip this step). I have Given all the Dimensions in the Above Picture you can follow that.

After Get Ready with the chassis now mount the motors on it using Hot Glue or may be Nut and Bolt arrangement, i'm here used Double Gum Tape it is strong and easily removable. .

Step 3: Mount the Arduino and Motor Driver on the Body

Step 4: It's Time to Upload the Code

connect the usb to Arduino and select port in the pc, Download the given Program and upload .

Attachments

Step 5: Connections

Now connect as per Circuit Diagram.

Be careful while connecting and If you have Doubt please Cross Verify with code

Step 6: Make the Attachment for Ultrasonic Sensor

As shown in the Picture make the Attachment , here i'm used Foam sheet, you can make with Acrylic Sheet also.

Now attach Ultrasonic and ir sensors .

Step 7: Connect the Battery and Now the Robot Is Ready

After completing all the steps the common errors or problems may Arise

To Troubleshoot that Follow the below steps

1) Calibrate the IR sensors

2) Check the Motor Direction and Fix that

3) Make sure the Connection as per the Code or Circuit Diagram

4) Still your problem is not fixed Then Contact me on instagram. id : ganeshpc007
