Nowadays cars and different vehicles have a huge impact in our everyday life. Millions or even a hundred million people using them for various porpuses such as transportation, touring or by simply for the joy of driving. Since the majority of these machines are controlled by humans unfortunately accidents can not be avoided. So far the automotive giants haven’t sat with folded arms, instead they installed and updated their products with the newest technology avaible. But even so these efforts, companies still weren’t satisfied with the results. This ambitious attitude caused the development of automatization what served to filter human mistakes. This task has never been an easy plan and it already consumed loads of engineering workhours. But if we ever want to succeed, we need to invest at least a few decades more.

In my thesis I will present the potential in the automatizated vehicles with It’s pros and cons as well as the steps towards the fully automatization. After this I’ll exam the matter of platoon desings and It’s solutions with an example. This will give you an insight over the used tools and devices operations in both hardver and softver sides.

In this particular case I used LEGO NXT 2.0 type of robots, which are being used in wide variety of educational institutions and it’s also avaible in our department. The softver backround is provided by LabVIEW developed by National Instruments. This program is known for the capability to serve the industry’s needs in most cases with it’s Softver Development Kit. The robots are avaible with different sensors. The ones I’m using during my presentations are equipped with ultrasonic distance sensors and with luminous intensity sensors as well.

The completed and documented creation completes the tasks set at the beggining of my exam. It is capable of following lanes and also programmed to complete more complex lane changing operations even It’s about a convoy of robots.
