## Drivetrains

### West Coast Drivetrain - [Onshape File](https://cad.onshape.com/documents/888fadc78be2b5e328c8cc2f/w/5071ff3a09cccc32a13f5f12/e/1908556125c3df6ce41c6e41)

This drivetrain incorporates two [2 Motor Drivetrain Gearbox - Through Bore](https://www.revrobotics.com/rev-21-2190/). Each gearbox drives two sprocket and chain systems to omni-directional wheels. This model utilizes the [NEO Vortex Brushless Motors](https://www.revrobotics.com/rev-21-1652/) and [SPARK Flex Motor Controllers](https://www.revrobotics.com/rev-11-2159/).

The full BOM is available on the[ product page](https://www.revrobotics.com/rev-25-3267/).

### 3in MAXSwerve Drivetrain - [Onshape File](https://cad.onshape.com/documents/881172ccbf1a3c6b84a7c7a5/w/47b88cdaad963852e7118016/e/910662262bf507b06f5cb8ce)

This drivetrain takes advantage of four [3in MAXSwerve Modules](https://www.revrobotics.com/rev-21-3005/), allowing the robot the ability to drive forward and backward, side-to-side, and rotate simultaneously without sacrificing traction. In this example the MAXTube has been cut to a shorter length than what comes in the drivetrain kit.&#x20;
