Cellphone operated Robot
Cellphone operated .pptx (Size: 302.07 KB / Downloads: 20) INTRODUCTION Conventionally, Wireless-controlled robots use rf circuits, which have the drawbacks of limited working range, limited frequency range and the limited control. Use of a mobile phone for robotic control can overcome these limitations. It provides the advantage of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controlles. Although the appearance and the capabilities of robots vary vastly, all robots share the feature of a mechanical, movable structure under some form of control. The Control of robot involves three distinct phases: perception, processing and action. Generally, the preceptors are sensors mounted on the robot , processing is done by the on-board microcontroller or processor, and the task is perfomed using motors or with some other actuators. Figures shows the block diagram and cicuit diagram of the microcontroller- based robot. The importmpant coonents of this robot are DTMF decoder, Microcontroller and motor driver. An MT8870 series dtmf decoder is used here. All types of the mt8870 series use digital counting techniques to detect and decodeall the sixteen DTMF tone pairs in to a four bit code output. The built -in dila tone rejection circuit eliminated the need for pre- filtering. When the input signal given at pin2 (IN-) single ended input configuration is recognized to be effective, the correct four bit decode signal of the DTMF tone is transferred to Q1 (pin11) through Q4(pin14) outputs. The atmega 16 is a low power, 8 bit, cmos microcontroller based on the AVR enhanced RISC architecture. It provides the following feature: 16kb of in system programmable flash memory with read write capabilities, 512bytes of EEPROM, 1KB SRAM, 32 general purpose input/output lines. 32 general purpose working registers. All the 32 registers are directly connected to the arithmetic logic unit, allowing two independent registers to be accessed in one signal instruction executed in one clock cycle. Step 6 : To connect the hands free with the circuit there are always two connections which come out of the phone, these connections are 1. Tip 2. Ring i'll prefer to use handsfree which have a straight jack (similar to the ones which we use in our ipods, but a thinner one) the tip of that jack is called the "tip" and the rest part behind the tip after a black strip is the ring So connect these two connections with the circuit and you will be done |
