I have taken up a "follow me" robot as my course project ,i am taking the following approach:
- Use one SR04 ultrasonic transducer only as transmitter which will be with me.
- Another SR04 module only as receiver which will be mounted on the robot.
I just know how to calculate distance using one transducer (SR04) ,but in this work I need to use only one as a transmitter and the other only as receiver.Is there any way where we could achieve above mentioned.
All I need is my robot should follow unique person and tracking distance less than One meter. If there is any other method welcome ..
