Method for device positioning in an enclosed environment

Hello all,

I will preface this question by explaining the constraints of my project. I would like to build an rc device capable of maneuvering around obstacles in a predetermined course of which i have the dimensions of to the nearest millimetre. The course will be 4 metres wide and 10 metres long on level with 4 obstacles (traffic cones) to avoid on said course. I am looking for a method of obtaining the position of my rc device (let’s say car) while it navigates the course so I may relay this to an Arduino Uno which will be giving the RC car directions based on where it is on the course. Basically my goal is to create a vehicle that using some sort positioning mechanism is able to navigate the course autonomously.

Thank you for reading
