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.

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

    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.
