The document describes the development of an autonomous micro robot for swarm robotics. The objective is to build a small robot that can be controlled by a master robot or take simple self-decisions using swarm intelligence. It discusses the hardware components including an LPC2148 microcontroller, IR sensors, motors, LCD and a Zigbee module for wireless communication. The robot's behavior is based on swarm intelligence principles with autonomous and decentralized control.

- 2. Objective The objective of our project is to build a small robot whose behavior can be traced from swarm intelligence. The robot is either controlled by a master control robot or can be able to take its own simple self-decisions automatically. This robot is also interfaced with a zigbee module that connects it to its master control unit, and can perform actions according to the command issued by master control unit.

- 4. INTRODUCTION The project is designed to build a small robot whose behavior can be traced from swarm intelligence. Swarm Robotics is an approach to the coordination of multi robot systems which consist of group of micro robots. These micro robots communicate with each other to perform a specific task. The robot is either controlled by a master control robot or can be able to take its own simple self-decisions automatically.

- 6. Block diagram description A microcontroller which is interfaced with an array of IR sensors, these IR sensors are fixed on the robot in such a way that they can sense any object present near its surroundings. The output of IR sensors is fed to the microcontroller that is programmed to take self decisions over changing the direction of the robot movement. The position control of the robot is achieved by DC motors and their drivers. This robot is also interfaced with a zigbee module that connects it to its master control unit, and can perform actions according to

- 9. Power Supply Transformer Transformers convert AC electricity from one voltage to another with little loss of power. Transformers work only with AC and this is one of the reasons why mains electricity is AC. Bridge rectifier A bridge rectifier can be made using four individual diodes, but it is also available in special packages containing the four diodes required. It is called a full-wave rectifier because it uses the entire AC wave (both positive and negative sections).
- 10. Capacitor A capacitor is a two terminal passive electronic component consisting of a pair of conductors separated by a dielectric. The capacitor blocks DC current and allows AC current . Regulator Voltage regulator ICs are available with fixed (typically 5, 12 and 15V) or variable output voltages.

- 12. Features of LPC2148 It has 2 ports ,each port consist of 32 pins total 64 pins. LPC2148 is the widely used IC from ARM-7 family. The ARM7 is a general purpose 32-bit microcontroller, which offers high performance and very low power consumption. It is manufactured by Philips. LPC2148 is a LQFP64 package.It is a RISC processor. Ram 32kb,Rom 512kb.
- 14. IR Sensors Need Of IR Sensor Because it has a good range which fulfills our requirements. It is very low cost and can be constructed on general purpose PCB. It is of very small size. Good immunity to ambient light and waves are invisible to eyes.
- 15. Working Of IR Sensor The working principle is totally based on change in resistance of IR receiver, which is similar to reflection of light. Here in this sensor we connect IR receiver in reverse bias so it gives a very high resistance if it is not exposed to IR light.
- 18. Liquid Crystal Display (LCD) LCD is a type of display used in digital watches and many portable computers. Here we use a 14 pin single row LCD of the size 16X2 (16X2 means 16 characters in the Colum and 2 rows for display)
- 19. Communication In Swarm Robots For working in a swarm, the master and slave has to communicate with each other. For this we use transmitter and receiver. The type of transmitter and receiver depends upon the range of communication. In the communication process, microcontroller plays a key role.
- 20. Categories In Swarm Master Robot This controls all the other robots in swarm. There will be only one master. They are intended to guide the slaves. They take decision from their own under critical conditions. Slave Robot This will be controlled by the master robots. There are so many slaves present in a swarm application. They are intended to do certain task given by the master. They can’t take own decisions by their own.
- 21. ADVANTAGES Man power not required. Low cost. Easy to use. Can be used to do the tasks which are hazardous for humans Time consumption is less.
