Autonomous Moving Backwards

Just out of curiosity Magi, what does MathUtils.pow(10, 6) do?

It raises the first parameter (10) to the second parameter (-6) power. So the result is 10^-6. I probably should use scientific notation instead. I am multiplying the time by this assuming the javadocs is correct that the timer returns the time in micro seconds.

You should probably multiply it by 10^-6 (if you want seconds).

Oops, fixed it now.

Our team is not using encoders for the drive system only the shooter this year. I just want the robot to drive backwards when the first 3 shots are fired. That takes about 9 seconds i have it for and then it will switch to low gear. then i want it to just drive straight back for the rest of the autonomous period.

In that case, you would want something similar to Magi's example, since that's based on time.

You could also create a commands for driving, shooting, etc. and then string them together in a command group and have them execute in-order. That would require a bit less tuning to get right, though it might take longer to initially program.

Be careful that you do not cross the center-of-the-field line
