The matching picture is a red dot award product. Please ask him if these four wheels are unreasonable. You must have known these wheels (omnidirectional wheel, McNum wheel, traditional wheel, universal wheel, etc.) when designing. His car, which has no steering function, can only use two such wheels. The rear driving force uses traditional wheels to complete the steering like a tank steering. If he uses four wheels at the same time, it will slip sideways. Does the small wheel on each wheel have power? It is not McNum's wheel. It is unreasonable for him that the two rows of small wheels should be staggered. It is strange that he can't sit on his ass! I can't imagine what they mean by using such wheels! Red dot now so don't pay attention to only know to collect money, may also the judges have other considerations? I feel the landlord is better and more reasonable! The landlord can try if, but it is a little expensive!

The picture you sent is similar to the toy car made by Dajiang. In the case of four-wheel drive, all four wheels can be used with wheat wheels. The disadvantage is that the efficiency is too low and the comfort is worse. The advantage is that it can be translated.

This wheel design is very reasonable, no problem, the front two are steering wheels, the back two are power wheels.

This picture of him is not a wheat wheel. He walked on a slope and slipped away.

Did you see the picture I sent? Have you looked at it carefully? I didn't say that the landlord's plan was unreasonable. I said that the wheels I sent were unreasonable. The small wheels on the wheels were not crossed. They were side by side. After walking on a slope, I slipped to both sides.

This is the improved version of McNum wheel. This steering is more flexible than the traditional universal wheel steering and has a smaller turning radius. There are many wheelchairs of this style. For this brand, there is already one called Hummingbird a1, which is already on the market. This is the new style. There are several brands of wheelchairs in China.

You're right about the side slip. The universal wheel and the McNum wheel cannot be tilted on the steep slope. They will tilt to both sides when they are tilted, and then they will automatically turn around. The slope of 20 is fine. If you shake a little more, you must ensure that it is fine to climb in a straight line. The front wheel drive is fine, and the wheelchair with high horsepower is fine. I have experienced 30 slopes. One did not pay attention to turning in situ and did not turn around.

Eldest brother, you still didn't look at my matching picture. What I said was that the wheel that won the red dot award in the matching picture was wrong, the wheel was wrong, and the arrangement of the small wheels was wrong. The slope would slide along the side. It was not the product of the landlord. The product of the landlord was no problem. The wheelchair with this wheel was put on the market more than ten years ago. It can be said that Japan's whill is referenced in China, in the past few years, I have watched the medical exhibition several times a year. Wheelchairs that did not have this appearance before in China are very traditional and old electric wheelchairs. It can be said that in recent years, there is not a single family in China that does not pay tribute, so you don't have to explain the basic principle of wheat wheel to me!
