autonomous programming

[solomason519]

hey im tryin to program autonomous.
I want our robot to move forward and track the opposite alliance's robot's trailer. I am clueless in programming autonmous mode. I need some help please. Can you guys show me how to use the default autonomous vi to accomplish this????? Please start from the beginning... we are running two motors for the drivetrain they are controlled by controller1 of the ds the left side wheels are run by axis 2 and the right side wheels are ran by axis 4.

adding the two color tracking example in the project explorer will get this going but i suggest you open he camera in the begin.vi and create a VI that feeds it the camera global information, then you have to use alot of advanced VI's and programming that alot of teams just aren't using. If your new to programming like I am it can get VERY complicated when you start working with PID's. I opted to just write a code that would move our robot, if you guys are new as well i suggest the same, and even 10 year teams are doing it so DONT feel like youll be a newbie for trying it

I dont fully understand you here, default autonmous?
and please explain your drive system

we have 4wd and each side is controlled by one sim motor each.we have a playstatin 2 controller controlling our drivetrain. the left side is controlled by axis 2 of the ps2 controller and the right side is controlled by axis four of the controller. iwant the robot to jus move around the field in auton mode...

The unmodified Autonomous Independent VI from the Basic Robot framework is a perfect place to start. It controls the drive motors using a series of Drive blocks and Delay & Feed blocks. I think it's very self-explanatory, but I'm an experienced programmer and I usually find it easy to understand well-written and well-commented code. Take a look at it, and if you have any questions about what it's doing, ask.

If all you want it to do is move, than open your motors in begin.vi

If you have four seperate motors liek i think your saying, then open all four on the seperate PWMs assuming you havent done so already [I would assume yes if you have teleop working]

Then i would suggest using a series of WHILE loops, use the set time VI and input a value you want to wait in seconds. Then wire the boolean out [itll be green] to the STOP if TRUE loop node [its a stop sign] then open your drive type in the while loop [this will be in your WPI robotis library]. i suggest arcade style. wire the RobotDrivedevRef into your drive style VI. just repeat these steps in a few more loops and wire the drivedevref from one VI to anouther. Remember that the drive devref is found by taking the ROBOTDATA [or something of the sort] and ungrouping by name[which is in the cluster library] then slecting it when the finger shows up as an icon select "RobotDriveDevRef" from the list.

or follow alans suggestion, both work
and that will get your robot at least moving

hope it helps.
