Problems with PID- PLEASE HELP!!!

Hey,

We are a rookie team and have been desperately (but unsuccessfully) trying to get the autonomous code provided by Mr. Watson to work.

Right now coming to the basics, when we ask the scripting code to drive 1500 mm, wait 20000 ms and then stop, the robot wheels just keep on driving. We are using the grayhill 63R128 encoders along with the ADXRS150 gyro. The gyro and the encoders work fine independently, but when put together in the Navigation code we get completely unpredicted results. We are not even on turning as of yet so i am not much worried about the gyro right now.

What could be wrong here? Has any other team who has had success with this please let us know what changes u needed to make in order to get things to work? We test this by putting the robot mobility on 4- 2" by 4" wooden stilts, can this make a difference despite the fact that the encoders are hooked up right?


Being a rookie we are completely clueless about this as we spent a lot of time making our mobility system and are short on time. Please help!

Thanks in advance,
vick.
