1. WIRELESS TARGET RECOGNITION AND COUNTER
ATTACKING ROBOT WITH LASER GUN ACTIVATION
ABSTRACT
Security is primary concern for every country. This Project describes a design of effective
automated system for Detecting, Tracking and counteracting Terrorist Attack by Wireless
Operated Robotic Gun.
In this project a shooting robot is built with base rotation, elbow and wrist motion with a
functional gripper to hold the laser gun. This robot is controlled by a microcontroller. The
user can control the robot motion using his mobile phone by Dual Tome Multi Frequency
(DTMF) signaling technology. When a target is found, automatically the system shoots the
target.
Relays are connected to the microcontroller using current driver circuits. Based on DTMF
signal sent by the user, the relays will be operated to control the robot.
This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator
is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output
of secondary of 230/12V step down transformer.
