ABSTRACT:

            This is a robot series utilizes four wheels to drive over just about any terrain. It works on any indoor surface and outdoor surfaces. This is an intelligent robot that can easily move on uneven surfaces too. This robot uses RF technology controlled by RF remote. This can be moved forward and reverse direction using geared motors of 60RPM. Also this robot can take sharp turnings towards left and right directions. This project uses ARM7 LPC2148 Controller

LPG Detecting robots play vital role in Natural Gas and LPG based process industries. This robot is controlled by an RF remote. This can be moved forward and reverse direction using geared motors of 60RPM. Also this robot can take sharp turnings towards left and right directions. This project uses ARM7 LPC2148 MCU as its controller. A high sensitive induction type metal detector is designed using colpitts oscillator principle and fixed to this robot. Also a wireless camera with voice is interfaced to the kit. A high sensitive LPG detector is designed using LPG sensor and fixed to this robot. When the robot is moving on a surface, the system produces a beep sound when LPG is detected. This beep sound will be transmitted to remote place. Simultaneously the images around the robot will be transmitted to remote place. We have provision for obstacle detection by using IR sensor.

This project is designed to interface temperature sensor to ARM based microcontroller.LM35 is used to sense the temperature. When sensor gets activated the change in temperature is indicated by a Buzzer sound.

The RF modules used here are STT-433 MHz Transmitter, STR-433 MHz Receiver, HT12E RF Encoder and HT12D RF Decoder. The switches are interfaced to the RF transmitter through RF Encoder. The encoder continuously reads the status of the switches, passes the data to the RF transmitter and the transmitter transmits the data.
