    SDS Colson Wheel (Wheel Only)

    With custom hubs, this offering from SDS has competition-tested performance combined with seamless integration into the MK4 and MK4i Swerve Modules.



    Colson Performa Wheels have been used extensively in BattleBots and FIRST Robotics Competitions, and are widely lauded as an intelligent choice for swerve. The durable co-injection molded construction of a thermoplastic elastomer tread permanently bonded to a polyolefin core helps ensure the wheel can withstand the rigors of robot competitions while being friendlier to non-carpeted surfaces and providing a more consistent performance throughout the life of the wheel compared to roughtop tread. 

     

    The aluminum hub is secured to the bevel gear using three screws which captures the wheel. This setup provides a simplified replacement process for heavy use during competition season.

    2" Compliant Wheel, 1/2 inch Hex, 35 Durometer Green

    #am-3462_green
    $9,50
    ( 85 En stock)

    Compliant wheels are not intended for moving robots, but moving objects. Compliant wheels give way to allow rigid objects to be manipulated easily. A line of multiple wheels on a driven hex shaft creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors. The wheels are sized for an interference fit and tend to stay in place on a shaft, though a shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing.

     

    The hex bore versions of this wheel are undersized, and are intended to be an interference fit on their respective hex shafts. This interference fit allows for effective torque transfer from the hex shaft to the wheel, as well as allowing the wheel to remain in place along the shaft without the need for spacers or collar clamps:

     

    Compliant Wheel Sizing

     

    Different durometer ratings give each wheel unique characteristics. Green wheels (35A durometer) are the softest and most compliant around objects, while orange (40A), maroon (45A), and blue (50A) wheels are increasingly firm. The increased firmness also allows the latter wheels to carry a higher RPM rating. Check out the downloads tab for a chart showing wheels and their maximum RPM.

    Solid Pool Noodle

    #am-5580
    $4,25
    ( 0 En stock)

    This item can only be purchased in multiples of 8

     

    These solid polyethylene (PE) closed cell foam noodles are great for building bumpers for the FIRST® Robotics Competition.

     

    This foam outperformed all other tested options when paired with a backing of Soft Tiles. 

     

    A rough estimation is that about 6-8 pool noodles are used for 1 set of bumpers depending on robot size. Noodles are required to be purchased in multiples of 8. Read the robot rules to ensure you understand how to create legal bumpers based on this year's rules.

    Compliant Star 1/2 Hex 35A Durometer

    #am-5123_green
    $16,25
    ( 38 En stock)

    Compliant Stars are the perfect thing for intake mechanisms. The soft material gives way to allow rigid objects to be manipulated easily. A line of multiple stars on a driven hex shaft creates a very effective roller that ignores variations in the objects being driven. The multiple-spoke design allows the star to act as a brush, creating more surface area to interact with and grab objects. This makes for high-performance intakes and internal conveyors. A shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing. Molded into the star are several guidelines. Cut the star at the lines (or elsewhere) to create more compact mechanisms. 

     

     

    Different durometer ratings give each Compliant Star unique characteristics. Green stars (35A durometer) are the softest and most compliant around objects, while orange (40A), maroon (45A), and blue (50A) wheels are increasingly firm. Black (60A) is quite firm, while the Gray (80A) is nearly rigid. The increased firmness also allows the latter wheels to carry a higher RPM rating
