Robot will not move in a straight line.

[JonahZa]

Hello all, I am currently trying to get my robot ready for competition. I am using the official kit (from https://www.wardsci.com/store/product?k ... 470352-240). I am running a very simple program just to get the robot to go straight for a specified amount of time. However, no matter what I do the robot either veers off to the left or to the right after starting, and then goes straight. Is there a solution for this? I've tried using different wheel orientations and changing the program itself, but the problem still occurs.

Thanks in advance.
