autonomous 4wheeled robot

hi friends!
i am working on a project which is an autonomous 4wheeled robot,its function is to avoid obstacles for that i am using max botix lv ez4 ultrasonic sensor,i am using two dc motors,now for now my problem is that i am unable to code my ultrasonic sensor so it can control my dc motors i am using l293d,as after surfing on net i got some idea that how can i control my motors through ping sensor using echo and trigger pin but maxbotix lv ez4 is different as compared to ping sensor can any one help me that how can i code it?

depressed!

The Ping sensor measures a distance. The maxbotix lv ez4 measures a distance. Take the Ping example, remove the Ping code to measure distance, insert the maxbotix lv ez4 code to measure distance. Done!

here is the code but its for ping sensor and servo motor what changes can i make so i can control dc motors via maxbotix sensor?
plz help

fauz:
here is the code but its for ping sensor and servo motor what changes can i make so i can control dc motors via maxbotix sensor?

Now show example code for reading distance from the maxbotix sensor.

here is the code for maxbotix sensor
