A Mecanum wheel is a type of wheel that allows a vehicle to move in any direction without changing its orientation. It features a series of rollers positioned at a 45-degree angle around the wheel's circumference. This unique design enables the wheel to slide sideways, rotate, and move diagonally, providing exceptional maneuverability. Mecanum wheels are commonly used in robotics and material handling applications, such as automated guided vehicles (AGVs) and robotic arms. Their ability to move in multiple directions makes them ideal for navigating tight spaces and performing complex movements, enhancing efficiency in various tasks.
