Re: Independent motorcontrol
This is a common type of programming error. You are not unique in having this problem. One thing I try to always do is to use {} in an if statement, even when it's not required... This code if (condition) function1(); is the same as this code if (condition) // preferred { function1(); } but this... ...

Re: autonomous tin can collector with LabView12
Well, I typed this up once, and it lost my reply. So, this one will be shorter. The very short answer is that you need to look into what the Loop Exit Condition does. In your first two loops, when it checks to see if it should exit, you have it set to true, so it will exit right away. I think you wa...

Re: autonomous tin can collector with LabView12
Looks like there are a few little issues with your program. The biggest problem is that there are several places that you're trying to tell the motors what to do, and there's not anything to indicate which of them can happen first. Some suggestions & comments: 1) The "NXT btns" block a...

Re: autonomous tin can collector with LabView12
Well, I don't have LV12 installed. Can you post a picture of the program?
What do you think the program is doing right/wrong?

Re: NXT-G 2.1 Bug?
What do you mean by "reset to their original position"?
If you're reading the values from the rotation sensor, they should continue.
Feel free to post your program.

Re: bluetooth connection problems
I would try a couple different things:
1) Turn them off, and try again
2) Remove the batteries, and try again
3) Go into the bluetooth setting for each NXT, and remove all pairings. Then try again.

Here's the best I can think of with what I want the robot to do. code in words while the light sensor is at 39 or below, power motors A and C; when it bumps the first obstacle and x == 0, rotate clockwise until light sensor is at 39 or below, back to powering motors A and C; when it bumps the secon...

Re: Starting from Scratch
Jess,
I suggest you start by looking into First LEGO League http://www.firstlegoleague.org/
That would help you better understand what's possible. The FLL season generally runs from September through December, but now is a great time for you to start learning what needs to happen.

Re: Help with NQC code
Steve, I need the robot to follow the line until it bumps into the obstacle (touch sensor), then back up about 4 inches, and then pick up the line that it needs to follow without going back in the direction it came from. That's a good start. Now, you need to expand on that a bit. 1) How does the ro...
