: To stay up to date with the quickly developing need of people, mechanical technology and mechanization assumes an unmistakable part all through. The paper presents a model which empowers the controlling of the robot distantly by means of cell phone through Double Tone Multi Frequency (DTMF) decoder. DTMF is perhaps the latest and cutting edge innovation for of information transmission. It is more effective and better than the Bluetooth and Wi-Fi as in the scope of DTMF is extremely huge for example the gadgets can be worked through DTMF independent of the geological area of the individual controlling it; additionally, DTMF is coordinated communication not at all like Bluetooth in which up to 7 gadgets can be matched and Wi- Fi where very nearly 10 gadgets can be subsequently giving greater security to the channel through which information is being sent. DTMF ordinarily discovers its utilization in protection observation just as call focuses. The utilization of DTMF can be additionally reached out by utilizing this innovation in everyday life, for instance, for contrastingly capable individual this can fill in as their all-inclusive arm permitting them to screen their homes from one spot and in any event, assisting them with picking and hold things by observation. .
