This is a pretty hard project. All the dead reckoning methods are useful but only partial solutions.

IR beacons are a common solution, but even they are fairly challenging for beginners. They were used in the MIT media lab and you can buy em from Pololu.

The google car uses LIDAR which is like a 360 degree range finder. In the hobby range, you might try using an ultrasonic range finder or a webcam. The range finder can be coupled with a motor so you can get a range of readings without turning your bot. This should be more than challenging for a noob. After that I'd switch to the webcam (which can't be processed on an arduino), but there are lots of options. Webcams are cheap and provide images with lots of information. The challenge is in processing them.
