AM14U5 - 6 Wheel Drop Center Robot Drive Base - 2023 FIRST Kit of Parts Chassis

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:

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.

This spacer is designed to fit on a shaft or screw that is 0.375 in. in diameter. Spacers help keep things in place in a multitude of ways. You can use this to slip over a shaft that is smaller than the inside diameter, between objects where it gets smashed between them with other fasteners, or help center a shaft of smaller size into a larger hole. Not seeing the length you're looking for? Consider stacking several together.

Specifications

• Inside Diameter: 0.375 in.
• Length: 0.5 in.
• Material: Aluminum
• Outside Diameter: 0.5 in.

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.

This 6 in. long cable is designed specifically for the 2x5 pin data port on the Talon SRX to provide external inputs. It can be used to connect the Talon SRX to feedback devices such as potentiometers, limit switches, analog & quadrature encoders as well as providing other future expansions options beyond what is currently supported.

This cable can be used with the following list of products:

• Talon Tach (am-3778)
• Talon SRX Encoder Breakout Board (am-2633)
• Talon SRX Analog Breakout Board (am-2634)
• SPARK MAX Brushless and Brushed DC Motor Controller (am-4261)
• Lamprey Absolute Encoder (am-4179)
• SRX Magnetic Encoder (am-3445)

This novel style of collar clamp is split into two pieces so that it can be attached without removing any shafts. The bore is a 1/2" hex. The flats on the perimeter allow for the collar clamp to be held in position or turned for better assembly control. 

This clamp has been designed and fabricated by BaneBots, and proudly sold through AndyMark.

Specifications:

• Material: Aluminum
• Bore: hex hole, 1/2 inch
• Outside Diameter: 0.94 inch
• Thickness: 0.375 inch
• Width Across Flats: 7/8 inch
• Weight: 0.020 pound
• Clamping Screws: #6-32 x 1/2" long (qty. 2)

Plastic spacers are included with this clamp, positioned between the two halves. These are to be removed before usage.

This simple bracket handles so many of your mounting needs! Mount motors or gearboxes anywhere and make axle supports with bearings - it's a do-it-all, put-it-anywhere bearing and motor mount bracket.

Any motor or gearbox with a 2-inch diameter bolt circle can be mounted in this bracket. The center hole is sized to hold a standard 1.125 inch outside diameter bearing.

Examples of motors with a 2 in. diameter bolt circle:

• 2.5 in. CIM Motor
• NEO Brushless Motor

Examples of gearboxes with a 2 in. diameter bolt circle

• PG Series Gearboxes
• 57 Sport Gearbox
• CIM Sport Gearbox
• Falcon Sport Gearbox

The AndyMark Climber in a Box is a robust, lightweight, configurable and affordable solution for climbing challenges historically present in FRC end game periods. The design of Climber in a Box has been inspired by many team designs along the way including 254 and 2056. The final prototype for this climber was developed in partnership with FRC Team 3940 CyberTooth for the 2020/2021 Infinite Recharge season. This mechanism has been battle tested with hundreds of climbs on a full weight FRC Robot without failures, both in development and real match play. Available in single and two stage configurations, this product should help teams of all levels elevate their team's performance at competitions.

This product uses a "spring out, winch back" powertrain strategy, using off-the-shelf 3.5lb constant force springs to raise the included Hook Kit, and 3mm Dyneema Rope to retract it with the included Winch Kit. Simply unspool the included rope using a planetary gearbox to raise the hook(s), drive the robot up to the bar, and winch it back to elevate your robot. The AndyMark Climber in a Box does not include a motor or gearbox, but is compatible with many off-the-shelf planetary gearboxes on the market that have a 2" bolt circle mounting pattern and support a 2" long 1/2" hex output shaft, including the highly durable blue Sport Gearboxes.

The bearing kits within this product are designed to go from 2" square 1/16" wall aluminum tubing, down to a 1" square 1/16" wall tube, with a 1.5" square 1/16" wall tube in between for the 2 stage flavor of this product. A combination of durable 608 bearings and custom molded plastic components provide the bearing surfaces for a free-flowing telescoping tube mechanism with no 3D printed parts. Each stage has a maximum travel of 24.5."

The AndyMark Climber in a Box is an unassembled kit of everything you need (besides a gearmotor) that is designed to not require any precision machining in order to make your FRC robot climb. The plates included within the Hook Kit, Bearing Kits and Winch Kit are all designed to be assembled and used as drill guides for match drilling their mounting locations onto the aluminum tubes. Each tube is pre-cut to a 30" length so no cutting of the tubes is required to achieve maximum travel.

Churro is a versatile extruded aluminum hex profile. The outside of this part is a 1/2 in. hex with small concave dimples which act as weight savings. There is an inside hole is sized at 0.2 in. in order to fit 1/4-20 thread forming screws. No tapping or threading is needed, as long as a thread forming screw is used. The outside hex size fits a 1/2 in. wrench or socket. 

The 3-foot churro, our most popular length and the best value on shipping, is available anodized in red, blue, purple, gold and black to dress up your robot. Anodized finish is hardy and doesn't flake off or add thickness like paint, but it is possible for a scratch to expose the bare metal beneath. Take basic precautions in your shop like watching for sharp tools or overtightening this churro in a vise.
