Mecanum wheel

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.
