    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.

    $28,99
    ( 24 En stock)

    Tired of hex clamp collars that cost an arm and a leg? Tired of stripping out the set screw on your clamp collar? Need to add a collar in an assembly and don't want to remove everything from your hex shaft?

    Me too! I've ran into all of the above scenarios multiple times building multiple robots. These collars are the holy grail -

    • split so they can easily be added or removed
    • lightweight 6061 aluminum
    • .5 oz (.031 lbs) for one hex collar
    • uses two 8-32 socket head cap screws that require a 9/64" allen wrench
    • $4.00 per collar, sold in 5 packs
    • anodized black for awesomeness

    #25 Chain Tensioner - QTY 1

    #ELEV-DRIVE-007
    $21,72
    ( 27 En stock)

    This turnbuckle chain tensioner integrates directly with #25 chain. Using a chain tool, the custom 1/4-20 link bolts replace a chain link and have the pin pushed back through it to become part of the chain. Then simply twist the center coupler to tighten or loosen the chain and tighten the jam nuts once your chain tension is perfect.

     

    All parts are made of steel including the coupler and the custom chain link bolts are 1/4-20 thread for increased strength. One link bolt is left hand threaded and the other is right hand threaded, so take care not to mix them up if purchasing multiple sets.

     

    Material: Steel, all of it.

    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.

    Entrapption Star .5 Inch Hex Shaft

    #am-0619a
    $15,60 $20,84
    ( 52 En stock)

    Our Entrapption Stars have two bore options, making them viable parts for both FRC and FTC! This product is frequently used as intake wheels for picking up game pieces. Made from silicone, they are flexible, yet firm, allowing for the ability to pick up objects of irregular shape.

    The 1/2 in. Hex Bore option is designed to be an interference fit on any 0.5 in. Hex Shaft.  This means the bore is actually 0.425 in. and it will be a tight press on, but keep the entrapption star from rotating.
