Let's Make Robots!

Project of a small vehicle

Hello, Im in university and have a task to make a vehicle, and they give you no information on how to make the vehicle. The task is to construct a vehicle that is able to following a tack. The component provided are, A chassis is provide with motors, gear boxes, wheels, a transistor capable of providing the drive current for the motors and fixing arrangement for printed circuit or strip boards to house the electronics are provided.The other components you can take it from the university stock room.You can also order component with a budget of 50 pound. 


They told me you can either make the vehicle using analogue, digital or microcontroller. Since I don't know how to use a microcontrroller i may not use microcontroller.


Can someone suggest me how to start the project?

In our hackerspace we developed a analog line follower with a simple transistor circuit. The costs should not be more than US$ 2.00


You can use a proto board as a chassis and motors you have in stock but need to take care of the current they draw.

do you thnk, if i put a ventilator in my line follower robotwould make it faster?

You have to make a line follower? What kind of track does it have to follow? You have a photo or drawing of the track? Does the track have obstacles? Have you decided which micro controller you will use? Do you have experience with programming? 

I suggest you first try to make the chassis moving by writing a simple program to control the motors. Then add some sensors and try to do line following, there are quite a few line following robots on this site. You can even find lots of code of line following robots with a simple google search.

Yes, the vehicle need to follow a line, the track that it have to follow is 

The second track, the real track in the race day will be given 3 weeks before the race day, the teacher said the track will be more sharper and more longer than this. I know how to use c programming to make simple program but I don't know how to use it to make a car move right or left. Do you think this is enough for controlling the small vehicle? I know a bit of VHDL too.

They told me to make a circuit for the sensor or something like that. 

ok thats  abit of  fun ,,, browse LMR for line following , look for ir reflectance sensor  or even LDR's chose a MCU and nuckle dwn they's a lot on "  line following " on google  have fun , come back with more specfic questions ,
