What distance sensors are better and best?
I want to use lasers as distance sensors, but I think they will be a little over budget, altough this is a paid for job :)
Yes, SRF05's clai, they can detect a broomstick on 3 meters.. but in reality they are not stable before say 1.5 meters.
1.5 meters when you are traveling at 25km/h is NOT a lot, when you even are set up with drifting tyres.
So I would like a little longer "view". And it can be pricey, say USD 50-70 for each sensor.
