(...) Hi Jonathon, It is possible to build a differential using the NXT parts. It is a bit big, but I have seen it done. I've not used this to make a car, but in general, I don't find three or more wheels interesting. Go for it. It is quite possible (...) (18 years ago, 8-Jan-07, to lugnet.robotics)

Hello, I'm just getting started with NXT and was wondering if anyone has successfully built a car-type robot. By this I mean a robot that uses one motor to drive the rear wheels and one motor to operate the front steering. The NXT kit does not (...) (18 years ago, 8-Jan-07, to lugnet.robotics)

(...) That machine is ingenious. I like the way he has his RCX bricks communicating by traveling along with the assembly line. I also like the frame he made to hold the wheels while the body was pushed onto them. Brilliant. (...) This reply is (...)

(...) Thanks Steve! It's perfect. I will use it in one of the NXT robots. But now, part of this project is to show some comunications between two robots, (and the other one is a RCX driven. It will also follow a line). I saw some time ago a small (...) (18 years ago, 3-Jan-07, to lugnet.robotics.nxt, lugnet.robotics)

(...) I built a project to do just what you want. In a tracked vehicle I have each track driven by a separate motor and each also drives one side of a 'differential' but in opposite directions. If both motors run exactly the same speed the sum is (...) (18 years ago, 2-Jan-07, to lugnet.robotics)

(...) Just one rotation sensor. The differential gives you the difference (hence the name) of the two sides. If it's zero, you're driving straight. A positive rotation means you are turning one way, and negative is the other. It's not pseudocode, (...) (18 years ago, 31-Dec-06, to lugnet.robotics)

Does anyone have some RCX code to make a simple differential drive (2 independent motor/wheel combinations) with 2 rotation sensors drive straight. I'm sure it's been done many, many times before and I don't want to reinvent the wheel here. NQC or (...) (18 years ago, 31-Dec-06, to lugnet.robotics)
