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)

Thank you all for the answers. My wife says I can't "play" until I clean my office and I guess this time she's right: I don't have a flat space left in here. I've been reading online a lot and found way too many interesting projects and ideas this (...) (25 years ago, 24-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)

Hi, yeah... me I just went through such trouble using Java. The RTS should be 'false'. Then by experimenting I found switching the DTR before and after sending to have some positive effect.

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)
