| 24 | * Utility class for handling Robot drive based on a definition of the motor |
| 25 | * configuration. |
| 26 | * |
| 27 | * The robot drive class handles basic driving for a robot. Currently, 2 and 4 |
| 28 | * motor standard drive trains are supported. In the future other drive types |
| 29 | * like swerve and meccanum might be implemented. Motor channel numbers are |
| 30 | * passed supplied on creation of the class. Those are used for either the |
| 31 | * Drive function (intended for hand created drive code, such as autonomous) |
| 32 | * or with the Tank/Arcade functions intended to be used for Operator Control |
| 33 | * driving. |
