Hey guys I was just wondering if you could help me out with a question I have.
I am making a wall avoiding robot which detects the wall using a ultrasonic rangefinder such as the LV-MaxSonar-EZ3 (http://bit.ly/lvy9DD)
However I found this one (http://bit.ly/kQiSmE) that is a lot cheaper and I want to know if it would do the same job or is it a completely different sensor all together?
Any help would be greatly appreciated.
