Our SpinTake has three bore options, making it a viable part for both FRC and FTC! This product is ideal as an intake "wheel" for picking up game pieces of varying shapes. Made from natural rubber, the SpinTake is flexible, yet firm. Its unique shape also allows it to be oriented to stay within the robot frame perimeter initially but can reach outside just by spinning. These work in a similar fashion to surgical tubing fingers on an axle, but are easier to implement and provide a cleaner look with more consistent results. 

The Hex Bore options are designed to be an interference fit on their associated Hex Shafts. This means it will be a tight press to install but will resist slipping under load. 

Specifications

• Bore: 5 mm Hex, Nub Bore, 1/2 in. Hex
• Length (Diameter): 3 in.
• Material: Natural Rubber
• Thickness: 0.5 in.

The Studica 192mm x 96mm Flat Bracket is a very strong  3mm. As with the other Studica Robotics building components, it has the common hole pattern which makes it easy to connect to other structure with very little or no additional machining required. You can easily connect to other channel, extrusions, bushings, bearing, mounting brackets and more so you can quickly assemble and disassemble robots and automated systems.

Specifications:

• Material - Anodized 6061-T6 Aluminum
• Thickness - 3mm
• Width - 96mm
• Length - 192mm

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.
