Introduction: A Follow Me Robot With Simple Circuit

Its a very simple and easy to make follow me robot. It can sense the presence of object to be followed using Infra-Red ( IR ) sensor. There are one IR Led and two IR photo diode (with back IR Filter) . When the IR gets reflected from a nearby object and back to both the receivers diode, the transistor based switches power ON both the motors and the robot moves forward. If the object moves left or right then any one motor gets switched on and the robo takes turn.

Step 1: Step by Step Video Instructions to Make It

Here is the video link to make it . Video

There is no micro-controller was used. Very simple circuit. Hope you will enjoy the making.

    Sir,please help me.?
    I don't why the motors are not moving as I connected in the circuit u provided??
    Help me sir??

    Great work ! :D can the robot follow a person? I'm working a project of a robot following his owner and i need help with that ..

    wow this looks really fun I'm really excited to start working on it!

    can the robot follow a specific object? maybe a kind of senor will be placed on the object?

    can you plz give me a complete circuite diagram to my mail id mukeshrobot@gmail.com

    I have a question regarding the 10k Ohm Pot. What resisitance do you have it set at. Thank you.

    hello you can put a voltage of 9 volts

    in the download are there all the details of the robot?

    thank you

    please give me the circuit diagram of this project as in that instead of photo diode i have to fix(TSOP1838B)ir sensor i am confused where to connect the pinouts of the transistor it has three pinouts and which leg i have to connect where in circuit i am new to electronics pls help me i want to make it my email id is patelsoham9982@gmail.com

    will it work with the ir sensor if yes please help me.

    can you email me all the detail of the circuit..pencil1aku@gmail.com..

    sory for inconvenient

    can I use photo transistors instead of photo diodes

    1 reply

    can be used. But always better to use IR Rx-Tx pair. This receiver is a photo diode but comes with IR filter and helps to avoid ambient light effect. Or you can you an IR module , which is even better.
