ultrasound sensor problems
since my last post I have been playing around with the programming of my beastie and am now thinking that most of my problems (getting stuck in corners , going towards obstacles) have very little to do with the software but with the unreliability of the sensor. Separate tests revealed that one of every 3 or 4 pings does not come back and therefore messes with the program. granted the sensor is a cheapy, but has anyone had better experiences with the more expensive models? Any advice welcome
