    The Thrifty Hub - Half Inch Hex - QTY 4

    Half inch hex hubs are often used to transfer motion between components in competition robots. This hub includes a thicker quarter inch flange that allows for tapping 10-24 / 10-32 holes or drilling and tapping to 1/4-20 sized holes. The Thrifty Hub is offered as a blank hex hub to teams to do further machining or leave stock as-is.

    3 inch Compliant Wheel, 1/2 inch Hex, 35A Durometer, Green

    #am-3945_green
    $12,25
    ( 18 En stock)

    You asked, we listened! These 3" diameter HD (heavy-duty) solid-core Compliant Wheels are intended for manipulating objects where you need a little 'give' in your intake system. These wheels deform out of the way to allow rigid objects to be manipulated easily. This makes for high-performance intakes and internal conveyors. These wheels do not require the use of expensive hubs to be driven, thanks to their integrated high strength polycarbonate hubs - which are made from the same mold that creates our Hex Molded Spacers.



    Different durometer ratings give each wheel unique characteristics. Green compliant wheels (35A durometer) are the softest and most compliant around objects, while maroon (45A) blue (50A) and black (60A) wheels are increasingly firm.

    $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.
