/**
|
|
* This file illustrates the concept of driving a path based on time.
|
|
* The code is structured as a LinearOpMode
|
|
*
|
|
* The code assumes that you do NOT have encoders on the wheels,
|
|
* otherwise you would use: RobotAutoDriveByEncoder;
|
|
*
|
|
* The desired path in this example is:
|
|
* - Drive forward for 3 seconds
|
|
* - Spin right for 1.3 seconds
|
|
* - Drive Backward for 1 Second
|
|
*
|
|
* The code is written in a simple form with no optimizations.
|
|
* However, there are several ways that this type of sequence could be streamlined,
|
|
*
|
|
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
|
|
* Remove or comment out the @Disabled line to add this OpMode to the Driver Station OpMode list
