【A driving way of using wheels】

《The driving way of using two wheels》

There is other way on the driving way of using four wheels. It’s four wheel drive 四輪駆動,but it’s different from the one which is used for an automobile. When changing course, it changes the direction on rotation of the wheels like the driving way of two wheels.

Controlling it is easy,but it can't make sharp turns there on the spot,but as to its power and speed,it’s better than the driving way of using two wheels.

《The driving way of using six wheels》

A rover which was used for a probe in the Mars is six wheel drive which is an extension of the four drive wheel. A suspension which makes some tires touch on the ground at least is used for the suspension,so even if it’s in an uneven place,it didn’t lose its drive 駆動力. We call it the structure of Rocker Bogie.

As to its structure,I can’t express it with my poor English,but its moving image is shown in YouTube ,so if you’re interested in it, please look at it.
