(...) 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)

| | Connect BT devices to the NXT without a passkey?
|
|
Is it possible to connect BT devices to an NXT without using a passkey? The device I'm trying to use (a Nintendo Wii remote) doesn't use passkeys, AFAIK, since when I connect it to my PC I skip the pairing process. (18 years ago, 28-Dec-06, to lugnet.robotics.nxt, lugnet.robotics)
