Question:

Why is the wheel not spherical?

Why is the wheel not spherical?

Answer:

A circle to scroll is the need for a shaft ... given the case of the difference between the spherical and circular shape big? Personal feeling wasted material
How do you turn?
The advantage of the ball is mainly to turn the flexibility, but the fault is too much. The same diameter spherical tire volume must be much larger than the traditional tires, the quality will be very large, transmission loss will be very high. While the spherical tire grip area is far less than the traditional tires, grip is also very low. Another problem to consider is tire wear. Conventional tire wear is relatively uniform, and spherical tires because of its universal characteristics, wear will not be uniform, after a period of time will seriously affect the dynamic balance.
Will Smith starred in "I, Robot" inside, seat Audi RSQ on the use of spherical tires. The theoretical principle of transmission is electromagnetic induction, so no transmission shaft is required. Of course there are more simple methods such as three-axis fixation. Said spherical tires can not be achieved, your life did not appear in a mouse called the mouse thing?
