Product Detail

Mecanum wheels consist of rollers with a special geometry and placed in a special way at 45 degree angles that enable the vehicle to move forward-backward, diagonally-laterally, turning in place and going in all directions. Mechanum wheels theoretically increase the degree of freedom of the vehicle it is used in. It was invented in 1970 by Bengt ILON, one of the Swedish company Mecanum AB engineers. Later, the United States military bought this patent and worked on development in Panama. These wheels were used in the army to move supplies and move ships.

During the forward-backward movement, all the rollers rotate and shift on the gearbox output shaft axis. During the diagonal movement, the rollers on only two wheels, one from the front and one from the back, make rotational and translational movements, while the rollers on the other wheel, which are in contact with the ground plane, rotate around their own shaft axes. During its lateral movement, the rear and front wheels rotate in opposite directions relative to each other. With the rotational movement turning into a lateral force, the rollers rotate on their own shaft axes and slide under the influence of the lateral force.

Mecanum wheels can be specially designed according to the working environment in which they are used or to do a certain job. The most important feature of Mechanum mobile vehicles is that the wheels of the vehicle can move independently of each other. This means increasing the degree of freedom of the vehicle. Vehicles with two degrees of freedom can only move to the target point by moving forwards and backwards or turning. However, these vehicles cannot move by approaching the target in the side direction. To improve this limited movement, four-wheel drive, four-degree-of-freedom Mechanum wheeled mobile vehicles use special steerable wheels. These developed wheels gave the vehicle the ability to move forward and backward, both in translational and lateral directions. Mechanum wheeled mobile vehicles with their special wheel mechanism; They provide great advantages as they are used without requiring a very large area and without changing the rotational angles of the wheel.

For a normal force in the direction of the wheel, angled freely rotating rollers translate some of the force in the direction of rotation of the wheel. Movement is provided by the friction force between the ground and the pulley. Depending on the direction and speed of each individual wheel, the combination of all the forces obtained creates a total force in the desired direction. Only a small surface of the reel touches the ground. On this surface, the reel rotates on its axis and the wheel is shifted. Mecanum wheel systems provide higher maneuverability, high speed control and stability, and the possibility of turning and parking in narrow spaces at low speeds in some designs. Numerous movements can be achieved by changing the rotation directions and speeds of independent wheels.

Basically, we can talk about 10 movements as forward straight/backward straight, right shift/left shift, forward and right diagonal, forward and left diagonal, back and right diagonal, backward and left diagonal, clockwise rotation and counterclockwise rotation. . During the forward and reverse movement, all rollers rotate on the gearbox output shaft axis and the wheel is shifted in the forward/backward direction. During its lateral movement, the rear and front wheels rotate in opposite directions relative to each other. A lateral force is created by the effect of the friction between the wheel and the ground, the rollers rotate on their own shaft axes and shift to the right/left with the effect of the lateral force. During the rotational movement, the left wheels and the right wheels rotate in relative opposite directions and the vectorial sum of the forces generated by the friction force makes the vehicle rotate. During the diagonal movement, the rollers on only two wheels, one from the front and one from the rear, make rotational and translational movements, while the rollers on the other wheel, which are in contact with the ground plane, rotate freely around their spindle axis.

The Mecanum wheel is an omnidirectional wheel that has the ability to move in any direction without changing the orientation of the wheel itself. This is made possible by the unique design of the wheel, which features a series of rollers or "treads" that are set at a 45-degree angle to the wheel's rotation. These rollers allow the wheel to move in any direction by rotating in a specific way, making the Mecanum wheel a popular choice for robots and other mobile devices that require precise maneuverability.

The Mecanum wheel was first developed in the 1970s by Bengt Ilon, a Swedish engineer who was looking for a way to create an omnidirectional wheel that could be used in vehicles such as forklifts and other industrial equipment. The design of the Mecanum wheel is based on a principle known as the holonomic drive, which allows for multidirectional movement without the need for additional steering mechanisms.

The Mecanum wheel consists of a central hub with a series of rollers or "treads" arranged around the circumference. These rollers are set at a 45-degree angle to the wheel's rotation, allowing the wheel to move in any direction by changing the speed and direction of rotation of each individual roller. The rollers are mounted on a set of axles, which are connected to a motor or other driving mechanism.

One of the key advantages of the Mecanum wheel is its ability to move in any direction, making it ideal for use in robotics and other mobile devices. The wheel can be used to move a robot forward, backward, sideways, or even diagonally, allowing for precise maneuverability in tight spaces or complex environments.

Another advantage of the Mecanum wheel is its simplicity and reliability. Unlike other omnidirectional wheels, which often require complex and expensive control systems, the Mecanum wheel can be controlled using a standard motor or other simple driving mechanism. This makes the wheel a cost-effective solution for a wide range of applications.

In addition to robotics and industrial equipment, the Mecanum wheel has also been used in a variety of other applications, including wheelchair design, mobile platforms for video production, and even amusement park rides.

In conclusion, the Mecanum wheel is a revolutionary technology that has transformed the world of robotics and mobile devices. With its ability to move in any direction and its simplicity and reliability, the Mecanum wheel has become a popular choice for engineers and designers looking to create innovative and agile mobile devices.

The Mecanum wheel, also known as the Swedish wheel or Ilon wheel, is a unique type of wheel that was invented by the Swedish engineer Bengt Ilon in 1973. Since then, the Mecanum wheel has found many applications in robotics and other fields. However, few people know that the Mecanum wheel has a special connection to France.

In the 1970s, Bengt Ilon was working for a French company called Fives-Cail Babcock. Fives-Cail Babcock was a well-known manufacturer of industrial equipment, and Ilon was working in their research and development department. Ilon was tasked with developing a new type of wheel that could move in any direction, without requiring complex machinery or steering mechanisms.

Ilon's idea was to create a wheel that had rollers mounted at a 45-degree angle to the wheel's axis. These rollers would allow the wheel to move in any direction, depending on the speed and direction of rotation of each roller. Ilon built a prototype of his wheel, and after testing it, he found that it worked perfectly.

The Mecanum wheel was born, and it quickly gained popularity in the robotics community. The wheel's unique ability to move in any direction made it ideal for mobile robots, especially those used in factories and warehouses. The Mecanum wheel was also used in other applications, such as conveyor systems, amusement park rides, and even military vehicles.

Today, the Mecanum wheel is used all over the world, and it has become a standard component in many mobile robots. However, its origins are often overlooked.
