On Sunday, January 6, the VEXpro team designed, prototyped and built a robot chassis and drivetrain intended for use by FRC teams in the 2013 game, Ultimate Ascent.

• 0.125" thick 5052-H32 Aluminum
• Frame Dimensions: 23.5" x 31.5"
• Chassis Kit Weight: 6.83 lbs (metal only)
• Supports 4WD, 6WD, 8WD
• Compatible with 4” and 6” wheels

Specifically engineered for robotic applications. Ideal for drive systems, arms, and lift systems.

• High current capacity
• Low voltage drop
• FRC Legal

Variable speed control for both 12 V and 24 V brushed DC motors at up to 40 A continuous current. Analog and quadrature encoder interfaces, high performance Controller Area Network (CAN) interfaces, and an RS232 port.

• Quiet control of brushed DC motors.
• High current capacity with low voltage drop.
• Color-coded screw terminals for all power wiring.

• Includes 12t Gear and Mounting Hardware
• Mounts to a CIM Motor 8mm shaft
• Mounts to other motors or gearbox using this similar shaft

Spike is a 20 Amp, H-Bridge Relay Module that is small enough to be remotely mounted almost anywhere on your robot. Spike is designed for driving small motors in forward, reverse, or stop (brake).

• Ideal for 2 independent solenoids, light, pumps.
• Design will accept auto-resetting circuit breaker.
• Compact design.

The CIM motor can be used to power a drivetrain or other mechanism on large competitive robots.

• FRC Legal
• 12V DC Motor

The Mini CIM has 2/3 the power of a CIM motor, in a similar form-factor and with the same mounting. Similar output speeds allow Mini CIM motors to be combined in mechanisms with full-size CIM motors using the same gearing. Use this motor interchangeably with CIMs in your designs, then swap them in and out to put your power where you need it most.

• FRC Legal
• 12V DC Motor

The BAG Motor is a motor designed specifically for medium-power applications on FRC robots. This motor is constructed similarly to the CIM & Mini CIM, with the sealed-case robustness FRC teams have come to love & trust.

The VersaPlanetary was created with the BAG Motor in mind. Use a 100:1 VersaPlanetary Gearbox to turn the BAG Motor into a low-RPM, high-torque gearmotor ready for use in your application.

• FRC Legal
• 12V DC Motor

The ultimate two-speed transmission for competition robots. Three different gearbox ratios options in a compact, light and easy to maintain package.

• Pancake cylinder included
• Designed for use with 2 CIM Motors
• Housing is completely enclosed
• AGMA 11 quality gears with teflon infused ceramic coating

Super efficient reduction in a small package.

• BAG, RS-550, RS-775 and AM-9015 motors
• Dozens of gear ratios from 3:1 to 100:1
• AGMA 11 quality steel gears

Three motors into a one stage gearbox with reduction up to 7:1

• 5.33:1, 6:1, 7:1
• Designed for use with 3 motors
• AGMA 11 quality gears with teflon infused ceramic coating

Two stage gearboxes with reduction up to 9.52:1

• 2 CIM Motors
• Housing is completely enclosed
• Compatible with US Digital Encoder (all hardware included)
• Compatible with Grayhill Encoder (coupler required)
• AGMA 11 quality gears with teflon infused ceramic coating

These wheels are 4" in diameter and 1" wide. Integrated VersaHubs allow for the mounting of two sprockets or gears without any additional hub pieces (one on each side).

• Glass-filled Nylon Hub
• TPR Rubber Tread with custom "W" tread pattern

VEXpro Traction Wheels are designed to be the ultimate in versatility and performance. These wheels include the VEXpro VersaKey mounting system, which ensures every sprocket, hub, and gear are perfectly piloted -- no more wobbly sprockets!

• Ships assembled in 1" configuration
• Includes hardware for 1.5” and 2” wide configurations
• Customize with VEXpro Tread

VEXpro is happy to offer 10-foot lengths of some more traditional FRC wheel tread; Roughtop and Wedgetop. Originally created as incline conveyor belting, these two tread types have been in heavy use by FRC teams for almost 15 years.

• High traction rubber tread with a fiberglass reinforced base
• Compatible with VEXpro Traction Wheels and many other wheel types
• Attach with rivets or screws (not included)

Rivets for Roughtop or Wedgetop tread. Change tread quickly using these rivets.

• Sold in a pack of 13 rivets.
• Requires a pop-rivet tool to install.

Omni-Directional wheels roll forward like normal wheels, but slide sideways with almost no friction (no skidding during turns). Use these wheels to make your robot turn smoothly or build a holonomic drivetrain.

• Glass-filled Nylon Body
• Compatible with VersaHubs
• Custom rollers for each wheel ensure a round wheel and smooth ride.

Ships fully assembled.

Mecanum wheels allow savvy robot designers to create drivetrains capable of moving in any direction using a standard chassis shape. Simply power each wheel with a different motor and change the directions the wheels spin to get your robot to move in different directions!

• Glass-filled Nylon Body, ABS-PC Roller Mounts, Rubber Rollers
• Compatible with VersaHubs
• Custom rollers for each wheel ensure a round wheel and smooth ride

Ships fully assembled.

VEXpro VersaHubs provide frustration-free torque transfer between wheels, gears, sprockets, and shafts.

VersaHubs include the innovative VersaKey mounting system -- VersaKeys transfer torque between coaxial items, and also ensure everything is piloted correctly.

The Kitbot chassis was designed in 2005 to provide FRC teams with a simple reliable drivetrain design, which emphasizes versatility and configurability. It has many adjustment options, and can be constructed in numerous size and orientation configurations.
