Implementation of Autonomous Metal Detection Robot with Image and Message Transmission using Cell Phone

This paper describes the implementation of autonomous robot prototype for metal detection. The robot scans predefined area strip by strip and detects metallic object. Two DC geared motors are used for controlling the movement of robot. The metallic objects are detected by simple R. F. based Colpitt's oscillator circuit using transistors and passive components. The robot has been provided with facility to avoid obstacles through LED sensor module. A novel feature of automatic transmission of image to user cell phone on metal object detection is incorporated. The usage of Multi-media Messaging Service (MMS) feature of cellular networks eliminates the constraints of range and cost of customized transmitter for message transmission. The system is based on AVR ATmega16 micro-controller. Any cell phone with camera and MMS facility can be used with the system. The other applications which can be developed based on similar concepts are also discussed
