Initial Idea:
our buggy is basically a line following robot. In this project we have to design a buggy which follows a black strip of line and stays on it .The buggy can be designed by using two simple and small motors, two free wheels, a piece of pcb which basically hold the motors wheels and the light sensors. The chassis of the buggy will be the main board of the buggy.






Part # Description
1 The base of the robot, also the main PCB.
2 Front skid
3 Free Wheel, shaped as a pulley
4 Plastic pulley
5 Battery holder
6 Pipe clamp use to hold the motors
7 battery pack
8 motors

Our buggy is gonna be of differential type where the forward and the backward movement of the buggy will solely depend on the movement of the two wheels attached at the back. The buggy will turn when there is a difference between the speed of the two wheels. This is a little complicated part in the project as the difference of speed of the wheels has to be different for different radius of turns. However the buggy we have to design for the project is not very complicated as the buggy undergoes a 90 degree turn which can be achieved when either of the two wheels stops to turn. For example if the buggy has to take a left turn the left wheel of the buggy will stop while the right wheel will continue to rotate forcing the buggy to turn
As shown in the above design there is a skid provided at the top will provide good balance to the buggy and as the buggy is designed for indoor use the friction won’t come into vital play. The battery will be placed at the top of the buggy body as this will raise the centre of gravity, increasing the moment of inertia.
