Design & Implementation of a Microcontroller Based Low Cost DTMF Controlled Acoustic & Visual Detecting Robot to Monitor Child & Aged Person

Technology provides us to control anything from a remote area. Nowadays, anyone can control a machine from all over the world. It is sometimes quite difficult to take care of a child or aged person of the house beside a job. A number of peoples effort human maid to monitor their child or old parents. In this paper, a Dual Tone Multi-Frequency (DTMF) controlled robot is designed to monitor child or aged person. In which, a child or aged person can be monitored directly by a robot. the robot can be controlled by a phone call and a camera will send live streaming of Audio and Video to the robot-controller anywhere in the world. Atmega2560 used as the processor with L293D motor driver, DTMF decoder, a pair of the motor, a pair of the phone for both Receiving and Sending end and a smart phone with an internet connection to transmit audio-video. A Computer or Smart phone is also needed in the receiving end to receive the live audio-video transmission. Arduino IDE used as the programming software. An android app named `IP WebCam' is used for video-streaming. This research will mitigate the difficulties of monitoring child or old person.
