AndyMark 4in. HD Mecanum Wheel 3/8in. Hex, Full Set
Enable omnidirectional movement
Support up to 200 pounds
Feature nine durable urethane rollers
Boast robust polycarbonate-steel construction
Ensure smooth and reliable operation
The AndyMark 4in. HD Mecanum Wheel 3/8in. Hex, Full Set is a sophisticated wheel system designed for advanced robotics applications. This set includes two 'right' and two 'left' wheels, essential for creating a functional mecanum drive system. The unique configuration of these wheels allows for omnidirectional movement, making them ideal for complex robotic maneuvers. The wheels are constructed with a molded black polycarbonate interior and a zinc-plated steel perimeter, ensuring durability and strength. Each wheel can support a load of up to 200 pounds, making them suitable for both drive and intake applications in robotics.
The design features nine gray urethane rubber rollers with a durometer rating of 80A, which are sandwiched between two steel plates. These rollers are mounted on a stationary brass tube, providing smooth and reliable movement. The wheels are engineered to create an 'X' pattern when viewed from above, which is crucial for the proper functioning of a mecanum drive system. This configuration allows the wheels to drive objects in one direction while simultaneously pushing them at an angle, enhancing the efficiency of robotic intakes.
The 3/8in. hex bore is molded directly into the polycarbonate center body, making it compatible with various robotic applications, particularly in light-duty scenarios such as FTC robots or non-drive train FRC items. The robust construction and thoughtful design make these wheels a versatile choice for robotics enthusiasts and professionals seeking reliable performance in demanding environments.
