【A moving way for all directions】

《If forming a single tire with some other tires,it becomes the one which can moves for all directions》

We don’t need only to control it but but the structure which moves forward,backward,left,and right without changing direction of the vehicle so as to make possible the moving way for all directions.

When trying to move with an ordinary tire,we can move forward and backward by changing direction of the rotation on the tire,but we can’t move both for left or right. Then we have to turn the direction of the tire either left or right. In short we have to change a course.

If using the tire of moving way for all directions, we can go ahead,go backward,move to right or left without changing the direction of the car.

《Give up!》

What is called オムニ wheel has been used for the tire which moves for all directions more than any other one.

To my sorrow,I can’t express on the moving way for all directions any more,for it’s too hard to understand.
