What kinds of sprocket(s) does Lego currently use with tracks? A long time ago (in decades), I remember a set that used Caterpillar-link-style tracks, and they used a long-toothed sprocket to drive the tracks. It might work to put one of those (...) (25 years ago, 25-Jan-01, to lugnet.robotics)

I guess I didn't word that very well. I didn't mean that you can make an inaccurate sensor look like an accurate sensor via software. What I meant is that you write your software to know that the sensor is not accurate, i.e. the software doesn't act (...) (25 years ago, 24-Jan-01, to lugnet.robotics)

In my experience, rotational sensors are accurate to within +/-5%. 100% accurate sensors would be great, but 95% accurate sensors are still very useful. You can compensate for the inaccuracy in various ways, e.g. in the software. IMHO, this is no (...) (25 years ago, 24-Jan-01, to lugnet.robotics)

I just got my 1st rotational sensor and have a quick question for you all. I have the following gearing on my robot. Point A gears 8 <--> 40 8 <--> 40 Point B so this is: (5:1) x (5:1) = (25:1) Right? Now if I put my rotational sensor at Point A, do (...) (25 years ago, 23-Jan-01, to lugnet.robotics)
