| 21 | * Utility class for handling Robot drive based on a definition of the motor |
| 22 | * configuration. |
| 23 | * The robot drive class handles basic driving for a robot. Currently, 2 and 4 |
| 24 | * motor tank and |
| 25 | * mecanum drive trains are supported. In the future other drive types like |
| 26 | * swerve might be |
| 27 | * implemented. Motor channel numbers are passed supplied on creation of the |
| 28 | * class. Those |
| 29 | * are used for either the Drive function (intended for hand created drive code, |
| 30 | * such as |
| 31 | * autonomous) or with the Tank/Arcade functions intended to be used for |
| 32 | * Operator Control |
| 33 | * driving. |
