Nice job on the code. I noticed that you did not increment your counter though. Also, you said you wrote this off the top of your head, is it the same stuff that is running/tracking your robot now? Thanks,

Hmmmm, good point. It does increment the counter in the program I am running on the bot, and other than that the only differences in the functional part (I never comment my actual code ) are that a) right now it tracks red, not green (for a demonstration tomorrow that could get us nine grand) and b) it doesnt say to put the drive code here, instead it uses a modified version of the default drive code. I realised today that I have not actually put the robot on the floor and had it drive with this code, but I have had it on blocks and it tracks nicely and the wheels definetly turn in the right directions. I will let you know after our demo tomorrow if it actually works .

That demo sounds sweet, hope that went well for you. I have seen our robot a total of 2 times, so its a bit tough for me to experiment with the code, so I appreciate your help. I still dont understand exactly what is going on with the camera, but I think I know enough now to scrape an auto mode together. I had tested something similiar to your code, but the bot may have been tracking the wrong direction or something, it was acting weird. I dont like the way the default camera code sets turning/forward speed so I think I am just going to make my own code. Again, thanks, and good luck

Ah. Well, the demo thingy is over and the bot sort of worked. But like I said I wrote that code I posted from memory, and come to find out I would have been better off using that, as in my code for the bot I neglected to put an else to stop the motors. Ever seen what a robot can do to a vending machine? Actually it hit the side so nothing actually broke but it was still cool. As it was though the people were still very impressed and I think we will get the money, I was just very annoyed with myself. Anyway, yeah once I fixed that it worked just fine.

im sure that someone has asked this before. but what are the numerical values for the range of the servo on the camera? is it -127 to 127 or what? is it 0 to 254 like the robot? need some help with this please.

[russell]

It is the normal 0-254 type number, but the range is somewhat decreased, I think the functional range is something like 47-212 or something along those lines. It says in one of the documents in the getting started file.
