(...) John, Seeing that GPS accuracy is on the order of several yards (optimistically speaking) what LEGO robot wouuld you build that could make good use of GPS, and how would it use GPS? Cheers S (19 years ago, 18-Jan-06, to lugnet.robotics)

(...) I have a great deal of experience with GPS. The accuracy you mention is indeed correct (the GPS I'm looking at right now is specd at 5 meters horizontal accuracy). However, when you look at second-by-second accuracy, it is much better. A great (...) (19 years ago, 18-Jan-06, to lugnet.robotics)

John, The reason I asked is that to get a Lego robot that is moving enough to even use GPS (read moving more than 5 yards, and outside no less) it will take a special build. Your *average* differential drive/steer robot with castor is not likely to (...) (19 years ago, 18-Jan-06, to lugnet.robotics)

I've played with GPS a fair amount too and your description (...) (19 years ago, 18-Jan-06, to lugnet.robotics)

Hi John (...) I think those wheels are too heavy, they require so much torque to move that the axles are at their limit. I'd rather use the narrow motorcycle wheels, or somewhat smaller ones, for example those from 4404. Jürgen (19 years ago, 19-Jan-06, to lugnet.robotics)
