Maze solving line following bot

Projects General Guidance
1

I have decided to make a maze solving line following bot.
Leaving he front ultrasonic sensor to detect obstacle, how many other ultra sonic sensors will I need so that it can detect the way to proceed. will I be needing two ICR sensor to make it detect the line??
According to u what kind of motor will be preferrebale for the job in sense of rpm, low or high??

What's an ICR sensor?

At least 2 sensors are required for line following, signaling left and right deviation from the line.

I don't see how line following is related to maze solving - what kind of maze do you have in mind?

My take on OP's description is that it's a grid of lines, not necessarily a maze with walls, where the lines themselves are the maze, ie dead ends and so on. So following the lines is the actual traversing the maze with say the left hand on wall rule, and when you hit an obstacle like a dead end you have to make a U and get out.

This is very well documented on the web!

Here is an instructable which explains how a simple robot would work -

You will need two sensors (to detect leaving the line to the left or right hand side). I then suggest taking a look at the different methods for maze solving. The simplest being the left hand on wall rule which has already been mentioned!

Will a bo motor of 150 rpm be enough to drive the bot through the maze?? Or a a higher rpm motor be required for it???

is it necessary to take three IR sensor to get better efficiency from the bot or will two sensors do the work??????

for overcoming an obstacle in the maze will one ultrasonic sensor do the work or we need to buy two of them????

what is the main work of an arduino motor shield??? is it really a necessary component for the bot???

as a revolving front wheel which one would be better a castor wheel or a servo??

You better buy a robot kit, where all components fit together. Then add your sensors and start coding.
