Swarm Based Walking Robot

Generally humans coordinate with each other to complete certain tasks like lifting heavy weights, carrying long items etc. Similarly we can achieve the same coordination between the robots using Swarm Technology. Through this project you are going to build two unique Walking Robots which works based on Swarm Technology.

You will need an Arduino Uno board for interfacing microcontroller with RF transmitter and Receiver module. Here the Encoder is already interfaced to Transmitter module and Decoder is interfaced to the Receiver module. Here you are going to build two walking robots where one will act as Master robot which gives commands and other one will act as Slave robot which will follow the Master robot. You will programme the microcontroller of Master robot in such a way that based on the sensors input, Master will walk and you will programme the microcontroller of the Slave robot to replicate the Master Robot exactly.

Project Description:

1. Arduino Uno: The digital and analog input/output pins equipped in this board can be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
2. Servo Motors: A servomotor is a closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is a signal (either analogue or digital) representing the position
3. Motor Driver: Generally the Arduino board is not capable of providing required amount of current for running the motors. So we use a device called Motor Driver which will provide sufficient current for driving the motors.
4. Encoder (HT12E): An encoder is a device that converts information from one format to another, for the purposes of standardization, security or compressions. It also use to convert Parallel Data into Serial Data.
5. RF Transmitter: An RF transmitter module is a small PCB sub-assembly capable of transmitting a radio wave and modulating that wave to carry data. Transmitter modules are usually implemented alongside a micro controller which will provide data to the module which can be transmitted.
6. Decoder (HT12D): A decoder is a circuit that changes a code into a set of signals. It is called a decoder because it does the reverse of encoding. It also use to convert Serial Data into Parallel Data
7. RF Receiver: An RF receiver module receives the modulated RF signal, and demodulates it.
8. IR Sensors: The component we use to find whether there is any obstacle in the path in which our trolley is going are IR sensors (Infrared).

Project Implementation:

1. Interface the RF Transmitter module and Servo motors with the Arduino board on the Master Robot
2. Interface the RF Receiver Module and Servo motors with the Arduino board on the Slave Robot
3. Power the Robots and upload the code
4. Test the Walking Robots by giving some obstacles in the Master robot path
5. The Master robot’s actions are immediately replicated by the slave Robot
