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.
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 -
General Dimensions:
Coral (also known as Game Piece 1) is a 11 ⅞ in. long (~30 cm) piece of 4 in. diameter Schedule 40 Cellular (Foam) Core PVC pipe. Coral has a 4-in. (~102 mm) inside diameter and a 4½-in. (~11 cm) outside diameter. The Coral sold here is from the same batch and manufacturer used on official fields.
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.

This product includes two 1.25 inch long half inch hex couplers. This product has been verified to clamp all the various standards of 1/2" hex, rounded hex and AM churro with significant clamping force.
Affordable and durable 2 inch squish wheels are now available. These wheels are commonly used by competitive robotics teams to move game pieces throughout their robot.
These wheels ship in packs of 10 for $3 per wheel and feature:
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.
Note: Molded plastic cases have begun shipping with all encoder orders!
The Thrifty Absolute Magnetic Encoder was designed to provide teams a lower cost option for absolute position sensing. Simply plug the included 3-wire PWM style cable into your controller of choice and read the included magnet's absolute position. This device can connect directly to the RoboRIO as well as the REV Spark Max or CTRE Talon SRX.

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.
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:
The Thrifty Clamping Bearing Block provides teams a quick and easy way to capture 1.125" OD flanged bearings when mounting to 2" x 1" or 1" x 1" box extrusion. Simply drill a pass thru clearance hole and insert the bearing which is then trapped against the extrusion wall's material.
