PIC-BASED PATH FINDING METAL DETECTOR ROBOT

PIC-BASED PATH FINDING METAL DETECTOR ROBOT
Abstract
One of the biggest challenges in constructing a robot lies in the control of its motors. In this project we use a PIC 16F84A microcontroller to control the stepper motors of the wheels.
The robot is mounted on a three motorized swedish or spherical wheels arranged in a triangle to make omnidirectional movement possible. Two target points are initially taken and the robot is made to move towards one of them depending on the input selection. An array of proximity sensors are used for detecting the obstacles.
By controlling the stepper motors, the robot is made to move in a tangential direction to the obstacle. The algorithm is written in such a way that the microcontroller checks the proximity sensors after a specified time delay. This is done in order to maneuver the robot again towards the target. This subroutine is employed whenever an obstacle is encountered till the robot reaches the target point.
A metal detector is mounted on the robot to detect the metals present in the way. This robot is used in various industrial applications such as terrestrial, underground and space explorations, navigation in hazardous environments and in military operations. Enhancements can be done by adding a series of modules on this robot for other specific purposes.

hello sir,i am a final yr. student of mechanical engg. our group is designing a similar model in a prototype form somewhat differnt as we are using microcontrollers relays n other electrical circuits rather than a metal detector.....so i wud b grateful 2 you if u guide us in this regard.... waiting 4 ur rep. at earliest sir...

sir we r plannin on starting a small scale robotic project we r doing our mechanical engineering , our idea was similar 2 yours but we dont know where to start and how , so it would be great if u told us where 2 gather info on this subject or better even u mail us the info at abhishek.iceman@gmail.com awaiting your reply

sir i m a student of engeenerin college n our college is organising a tech fest so my freinds n i had decided to make a chalk following robot which works similar to it but can't find out 4m where to start so plz could u mail me it to phenoix89@gmail.com

Hello sir i am a 3rd year EE student. And i want to build a robot based on the combination of obstacle detecting and metal/radiation detecting but with special functioning. I want to know how i can i get the complete info about it. So can you please mail me and i will tell you about the special functioning. That i thought in my minds when and my id is (Sunnyminu007@gmail.com) my name is Sandeep i am from kakatiya institute of technology and science collage in WARANGAL andra pradesh.
