West Coast Drivetrain (Product Page)

The VersaChassis is the first product co-developed by the engineering teams at VEXpro and WestCoast Products. This chassis provides the “West Coast” style drivetrain in a very versatile package. No other similar products on the market allow for a fully custom configuration like the VersaChassis.
In addition to functioning as part of our system, all of these products can be easily integrated into custom drivetrain solutions.

Framing Components

This chassis itself is assembled using 2” x 1” Punched Tubing and Aluminum Gussets. Designers can configure it into a variety of shapes & configurations using nothing but a saw and hand drill. Users can easily mount any of the West Coast Products gearboxes & wheels using the provided Bearing Blocks.

Motion Components

To hold the Bearing Blocks in place, we have provided cams which attach to the side of the drivetrain. These cams allow for the simple belt or chain tensioning that "West Coast" style drive users love.

Battery Box (Product Page | Manual)

The Battery Box kit is one of the easiest ways to securely mount your robot battery to your chassis. The box can be mounted via any of its attachment holes or even sandwiched around a piece of 2”x1” tubing, and retains the battery geometrically with its precision-machined pocket and easy attachment strap. Alongside the battery mount are special features designed to mount the 120 amp main breaker and the battery cable connector, giving teams a strongly-attached, predetermined space for these commonly forgotten control system components. Loose battery parts are a thing of the past with the WCP Battery Box!

Notable Features

• Built in SB50 mount with security hole for connecting SB50 • Multiple mounting locations for Main Breaker Mount • Mounting holes work with any set of holes with 2” center to center spacing • Slots for battery strap • Mounts directly to Punched Tubing

Swerve Drivetrain

Swerve Drivetrains have grown in popularity throughout FRC, because of all of the advantages that come with it, such as allowing robots to engage in omnidirectional movement, without having to turn, have superior maneuverability, and increased traction. Each module also has its own motor for driving the wheel, which gives the robot complete control over the speed and direction of each wheel.

Swerve X (Product Page | Manual)

The newest generation of our swerve drive module, designed from the ground up to utilize the powerful Kraken X60 brushless motor to improve performance and remove complexity. This new design is smaller, lighter, and more versatile than our previous module, and truly makes omnidirectional driving as simple as plug and play.
  • Modules accept multiple motors: Kraken X60 - 775pro - 550 motors.
  • Natively supports CAN and Mag Encoder
  • Alignment holes to zero module.
  • Clearance holes so motors can be removed without disassembling gearbox.
  • Easy to install encoder locations
  • Flipped and Non Flipped option
  • Wheel height is the same regardless of configuration, so it is possible to mix and match modules on robot.

One of the primary benefits of this configuration is that it allows for a much less complex drivetrain assembly experience. Simply cut four Tubes to your desired length, and you’re just about good to go.

Tube Mount

The image below shows recommended assembly instructions for one corner of the frame. While it shows the frame being assembled with both the Aluminum Tube Plug (WCP-0374) and the 90 Degree Gusset (WCP-1060), it is also acceptable to use just one or the other.
If you are assembling the frame with a gusset, make sure to install it on the opposite side of the tube from the Tube Mount Swerve X Module.

Corner Mount

The Corner Mount Swerve is the new mounting style used in the Swerve X. This mounting style allows for much more space inside the drivetrain for other mechanisms when compared to the other Swerve X configurations.

Support Plates

WCP offers two different support plates to support Bottom Mounting and Top Mounting options for the Corner Mount Swerve variations.

Motion Blocks (Product Page)

Plate Bearing Blocks

The new Plate Bearing Block simplifies the sliding element of FRC turrets
  • Compatible with 1/2” OD bearings.
  • Easy to assemble and maintain.
  • Smooth rotation
  • Increased Durability

SplineXL Bearing Blocks

The WCP Bearing Blocks provide a simple and easy solution to mounting bearings to a tube. Perfect for the "West Coast" style drivetrain, these bearing blocks provide multiple ways to accomplish the same goal: adding a slot to the tube for the more customizable Sliding Bearing Blocks, or simply clamping around the tube with the easier Clamping Bearing Blocks.
Available Sizes:
  • 2" Bearing Block (Centered, SplineXL Bore)
  • 2" Bearing Block (.06" Offset, SplineXL Bore)
  • 2.5" Bearing Block (Centered, SplineXL Bore)
  • 2.5" Bearing Block (.06" Offset, SplineXL Bore)

Elevator Blocks

The new Elevator Bearing Blocks simplify the sliding element of FRC Elevators. Instead of requiring 4 gussets for each corner of each stage of the elevator, the Elevator Bearing Block simplifies all those parts down to one easy to assemble block.
Notable features:
  • Fewer parts and no plates.
  • Compatible with 1/2”, 5/8”, and 3/4” OD bearings.
  • Easy to assemble and maintain.
  • Elevator stages can be assembled much closer together, wasting less space.
