    NeveRest Orbital Gearmotor (Gear Ratio: 50.9 to 1) JST-VH-2 Connector

    #am-4609b
    $42.90
    (1091 In stock)

    The NeveRest Orbital gearmotor is a robust planetary gearmotor designed for FTC. With many ratios to choose from you can find the right motor for you, from a fast spinning intake to a high reduction arm, all are possible with NeveRest Orbitals. They have a pre-installed encoder and an output shaft directly in the center of the output face. The shaft is a 6 mm D and the gearbox housing is 37 mm in diameter.

    NeveRest Classic 40 Gearmotor, JST-VH-2 Connector

    #am-2964b
    $38.95

    The NeveRest 40 is a gearmotor with an attached encoder. The output shaft geometry and the gearbox housing diameter is similar to what FTC teams are familiar with. The shaft is a 6 mm D and the gearbox housing is 37 mm diameter.

    FIRST Legality:

    • According to the FIRST Tech Challenge Game Manual Part 1, Rule RE10, this is legal for the 2020-2021 FTC Game. 
    • According to the FIRST Robotics Challenge Game Manual, Rule R27, this is legal for the 2020-2021 FRC Game as it uses the NeveRest am-3104 motor.

    Encoder:
    There is an encoder mounted to the backside of this motor. It is a 7 pulse per revolution (ppr), hall effect encoder. Since the motor's gearbox has a 40:1 reduction, then the NeverRest 40 output shaft provides 280 ppr.

    Encoder Cable Options:
    NeveRest motors do not come with an encoder cable as we offer 3 cable options: 

    am-3926a allows you to connect the encoder directly to the FIRST Tech Challenge REV Controller.

    am-2992 has the 4 encoder pins joined in one housing using standard 0.1" spacing.

    am-2993 allows you to break out the 4 pins separately if you need them in a different order.
    Working with the Encoders:

    485 Servo Pack

    #39197
    $51.33

    485 Servo Pack  is one of the best choices for rugged robotic applications. This servo’s great performance and durability are a combination of karbonite gears, high-performance circuitry, and a ball bearing-supported output shaft. Karbonite gearing is nearly four times stronger than nylon gears and provides virtually wear-free performance. Standard rotational range is 90 degrees, but it can be operated to 180 degrees with controllers capable of generating a pulse range from 600 usec to 2400 usec. Produces nearly 84 oz-in of torque power.

    2" Compliant Wheel, Nub Bore, 35 Durometer Green

    #am-3572_green
    $8.00
    (In 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.
