Omni wheels, also known as omnidirectional wheels or poly wheels, are specialized wheels designed to provide full 360-degree movement and exceptional maneuverability to vehicles and robots. These wheels have a unique construction that enables them to move not only in a straight line but also laterally and diagonally, making them highly versatile for navigating in any direction.
Omni wheels consist of a central hub with multiple small rollers or wheels mounted around its circumference. The rollers are typically set at a 45-degree angle to the wheel's rotational axis, allowing for multidirectional movement. The arrangement of the rollers ensures that the wheel can roll freely in any direction, independently of the other wheels.
