# Channel Drivetrain This section outlines the steps required to build a six-wheel, channel-based, differential drivetrain. This design is a good starting point. However, modification maybe required to address the specific needs of the robot being designed. This design is flexible, allowing for different wheel types depending on the overall requirements of the drive train. The assembly of this drivetrain is broken into a few sections. This allows for a team of people to work on different tasks to complete the build quicker. Each section begins with what parts and the quantity of parts needed to complete the steps in that section. A list of required materials for all sections is listed below. | **Channel Drivetrain Resources** | | :--------------------------------------------------------------------------------------------------------------------------------------------------: | | [Channel Drivetrain CAD - Onshape](https://cad.onshape.com/documents/0aaa7f336e30d51b49f1c205/w/f2c9af258dc1457cbb379bbb/e/28c891cfaaece9ffbd90cb84) | | [Channel Drivetrain CAD - STEP](https://store-t3eo8vwp22.mybigcommerce.com/content/cad/Channel_Drivetrain.STEP) | ![](/files/-Me6UZLVz3Ijr6sZx7qN) ### Video Build Guide {% embed url="" %} ### Kit Options The Channel Drivetrain is built out of the following kits: #### FTC Starter Kit V3 Base #### FTC Starter Kit V3.1 Base | Part Number | Description | QTY. | | -------------------------------------------------------------------------------------------------- | -------------------- | ---- | | REV-45-3529 | FTC Starter Kit V3 | 1 | | [REV-45-3529](https://www.revrobotics.com/rev-45-3529/?searchid=4723969\&search_query=starter+kit) | FTC Starter Kit V3.1 | 1 | #### FTC Starter Kit V2 Base | Part Number | Description | QTY. | | ----------- | ---------------------- | ---- | | REV-45-1270 | FTC Starter Kit V2 | 1 | | REV-45-1884 | V2 To V3 Update Bundle | 1 | ### Full Bill of Materials | **PART NUMBER** | **DESCRIPTION** | **QTY.** | | ------------------------------------------------------------------------------------------------------ | ----------------------------------------- | -------- | | [REV-41-1762](https://www.revrobotics.com/45mm-x-15mm-C-Channels/?searchid=4720330\&search_query=1762) | 45MM X 15MM C CHANNEL - 408MM | 4 | | [REV-41-1767](https://www.revrobotics.com/45mm-x-15mm-C-Channels/?searchid=4723715\&search_query=1767) | 45MM X 15MM C CHANNEL - 248MM | 1 | | [REV-41-1687](https://www.revrobotics.com/rev-41-1687/) | U CHANNEL ENDCAP | 4 | | [REV-41-1432](https://www.revrobotics.com/rev-41-1432/) | 15MM EXTRUSION - 420MM | 2 | | [REV-41-1348](https://www.revrobotics.com/rev-41-1348/) | 5MM X 90MM HEX SHAFT | 6 | | [REV-41-1324](https://www.revrobotics.com/rev-41-1324/) | 3MM SPACER | 12 | | [REV-41-1323](https://www.revrobotics.com/rev-41-1323/) | 15MM SPACER | 2 | | [REV-41-1326](https://www.revrobotics.com/rev-41-1326/) | THROUGH BORE BEARING - SHORT | 14 | | [REV-41-1329](https://www.revrobotics.com/rev-41-1329/) | THROUGH BORE BEARING - LONG | 4 | | [REV-41-1338](https://www.revrobotics.com/rev-41-1338/) | 10 TOOTH #25 SPROCKET | 8 | | [REV-41-1365](https://www.revrobotics.com/rev-41-1365/) | #25 ROLLER CHAIN - 10 FT | 1 | | [REV-41-1492](https://www.revrobotics.com/rev-41-1492/) | M3 STANDOFF - 40MM | 8 | | [REV-41-1702](https://www.revrobotics.com/rev-41-1702/) | TENSIONING BUSHING - 39MM | 8 | | [REV-41-1327](https://www.revrobotics.com/rev-41-1327/) | SHAFT COLLAR | 12 | | [REV-41-1600](https://www.revrobotics.com/rev-41-1600/) | ULTRAPLANETARY GEARBOX KIT & HD HEX MOTOR | 2 | | [REV-41-1621](https://www.revrobotics.com/rev-41-1621/) | ULTRAPLANETARY OUTSIDE MOUNTING BRACKET | 2 | | [REV-41-1305](https://www.revrobotics.com/rev-41-1305/) | 15MM PLASTIC 90 DEGREE BRACKET | 12 | | [REV-41-1267](https://www.revrobotics.com/rev-41-1267/) | 90MM GRIP WHEEL | 4 | | [REV-41-1190](https://www.revrobotics.com/rev-41-1190/) | 90MM OMNI WHEEL | 2 | | [REV-41-1359](https://www.revrobotics.com/rev-41-1359/) | M3 X 8MM HEX CAP SCREWS - 100 PACK | 1 | | [REV-41-1361](https://www.revrobotics.com/rev-41-1361/) | M3 NYLOC NUTS - 100 PACK | 1 | ### Sub-Assembly Links {% content-ref url="/pages/-M8XAxKfdvyPhZ9sl1XI" %} [Single Sprocket Shaft Assembly](/duo-build/channel-drivetrain-build-guide/single-sprocket-shaft-assembly.md) {% endcontent-ref %} {% content-ref url="/pages/-M8XB5WPCXT8sWnpD8fT" %} [Double Sprocket Shaft Assembly](/duo-build/channel-drivetrain-build-guide/double-sprocket-shaft-assembly.md) {% endcontent-ref %} {% content-ref url="/pages/-M8XB5wGMP5CCbG1VEXQ" %} [Drive Shaft Assembly](/duo-build/channel-drivetrain-build-guide/drive-shaft-assembly.md) {% endcontent-ref %} {% content-ref url="/pages/-M8XB6EQX7rnFyLr9MeF" %} [UltraPlanetary Gearbox Assembly](/duo-build/channel-drivetrain-build-guide/ultraplanetary-gearbox-assembly.md) {% endcontent-ref %} {% content-ref url="/pages/-M8XBLCM-dtjFaWr6Aop" %} [Making the Chain Links](/duo-build/channel-drivetrain-build-guide/making-the-chain-links.md) {% endcontent-ref %} {% content-ref url="/pages/-M8XBLUQy1LOdaXfLi6R" %} [Drive Rail Assembly](/duo-build/channel-drivetrain-build-guide/drive-rail-assembly.md) {% endcontent-ref %} {% content-ref url="/pages/-M8XBLyZ-SGSQHklad72" %} [Final Assembly](/duo-build/channel-drivetrain-build-guide/final-assembly.md) {% endcontent-ref %} ### --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.revrobotics.com/duo-build/channel-drivetrain-build-guide.md?ask= ``` The question should be specific, self-contained, and written in natural language.
