2023 Game Piece Cube

Each CONE (am-4700_syc) is a yellow 1 ft. ¹³⁄₁₆ in. (~33 cm) tall rubber marker cone and weighs 1lb 7oz (~653 g). Each CONE has an 8⅜ in. (~21 cm) +/- ⅛in. (~3 mm) square base with ¼ in. (~7 mm) tall feet.

Each CUBE (am-4700_bpc) is made of purple PVC fabric and is marked with a FIRST logo. The CUBE is a cube-like shape, inflated to 9 ½ in. (~24 cm) +/- ¼ in. (~6 mm) as measured from face to face, but these ship deflated. A CUBE has rounded corners, may not have flat surfaces, and the length, width, and height of the sides may not be equal dimensions. A CUBE weighs 2.5 oz (~71 g). 

The Cube Measurement Jig (am-4700_cmj) is a tool developed by FIRST to calibrate CUBE inflation at events. The appropriate range for CUBE inflation is between when the cube can lift the jig off the ground due to it's inflation, and when the cube touches both sides of the jig at the same time. The total weight of the jig is important in determining the minimum bound. 

This new custom designed collar clamp has been designed specifically with FIRST Robotics Competition teams in mind. This product is Out of Stock until Mid March

This is a Heavy Duty Hex Bearing which outperforms our previous 1/2" Hex Bearings as it has a Heavy Duty Inner Race. This FR8ZZ-HexHD bearing, 1/2" hex bore, flanged, heavy duty inner race, shielded ball bearing, has an inner race that is thicker and stronger than our recent offering of a similar bearing (am-0279). This bearing has more material between the corners of the hex bore and the edge of the race making it stronger and much less likely to crack under high load.

This bearing is guaranteed to have a stronger, thicker race. 100% of these bearings have been quality checked for a smooth fit over 1/2" hex stock here at AndyMark. Many of our long-time customers will recognize this bearing, as it is the same version we sold back in 2008-2011, and we did not have any failures. Now, it is renamed and quality checked for your high load needs - including drive chassis with cantilevered wheels.

Specifications:

• Inside diameter: 0.500-0.502 inch hex bore
• Outside diameter: 1.125 inch
• Flange thickness: 0.062 inch
• Overall thickness: 0.312 inch
• Weight: 0.05 pound

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 axle creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors.

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), blue (50A), and black (60A) 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. 

Please note maroon wheels are only intended for use in FTC. If more powerful motors are used to drive it the spokes may fail.

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:

This is the "500EX Hex Hub" the bore is a 1/2" Hex Hole. It is a slightly different version of the 500 Hex Hub. It is manufactured differently, as it is extruded. Also, there is a 1.124" diameter boss on each side of the hub flange, providing a location for 1.125" bore flat sprockets. Are you having a hard time keeping your sprocket concentric with your hub? This hub is the trick.

This is the hub featured in the 2014 and 2015 Kit of Parts Drive Chassis and fits all AndyMark wheels. 

Specifications:

• Material: 6063 Aluminum
• Bore: 1/2" Hex
• Bolt Pattern: 0.204" diameter holes, evenly spaced on a 1.875" diameter bolt circle
• Outside diameter: 2.25"
• Weight: .088

• Hole Size For Stud: 0.25 in.
• Material: Copper
• Overall Length: 2.03 in.
• Tongue Width: 0.48 in.
• Weight: 0.01 lbs
• Wire Strip Length: 1.18 in.

These custom designed collar clamps have been designed specifically with FIRST Robotics Competition teams in mind. The one-piece collar clamp is a nice fractional 1/2 in. width to make shaft stackups easy. The clamping force is provided by a 10-32 socket head screw, which is bigger than most used in the competition marketplace.  This provides a high-strength clamping solution that shouldn't strip out when you need it most. You can even replace the 10-32 screw if it becomes lost with the screws historically used in the AM14U family of chassis. These thoughtfully designed collar clamps also have small bosses on each side. This allows these collar clamps to be installed directly adjacent to an FR8ZZ Round or FR8ZZ Hex bearing without rubbing on the outer races for smooth operation.

Snap action breakers are used commonly in mobile robot applications such as FIRST Robotics Competition power distribution boards. We offer several amperage versions.
