DESCRIPTION AND WORKING:

Conventionally, wireless-controlled software arms make use of RF circuits, which have the drawbacks of limited functioning range, limited frequency selection and limited control. Use of a mobile phone for automatic arm control can conquer these restrictions. It provides the huge benefits of robust control, working selection as huge as the coverage part of the service provider, no interference to controllers or more to twelve regulates. The power over robot arm involves three distinct levels: reception, processing and actions. Generally, the preceptors are sensors attached to the robot, processing is performed by the on-board microcontroller or perhaps processor, plus the task (action) is performed applying motors or with some other actuators.

In this project, the robot adjustable rate mortgage is controlled by a cellular phone that makes a call towards the mobile phone mounted on the robotic arm. For the duration of a contact, if any kind of button is definitely pressed, a tone corresponding to the press button pressed is definitely heard in the other end from the call. This tone is known as ‘dual-tone multiple-frequency' (DTMF) sculpt. The robot arm perceives this DTMF tone with the aid of the phone stacked in the robotic arm. The received strengthen is processed by the ATmega16 microcontroller with the aid of DTMF decodierer MT8870. The decoder decodes the DTMF tone into its equivalent binary...
