This year, look at a brand of Qihui Toys , a brand of interesting technology cars that may not be known by many people .There is no way to know how fun it is from the name alone, so no more nonsense, let’s take a look now!
【Box photos】 Was it attracted by this unique wheel? This is called Mecanum Wheel , which can flexibly and conveniently achieve all-round movement, very good!The patent information of this Mecanum wheel is on the side of the box.The following is the introduction of Mecanum wheel by Baidu Encyclopedia: The mecanum wheel is a patent of the Swedish mecanum company. This embodiment is based on a full range of movement there are many principle located on the periphery of the wheel axle center of the wheel, the periphery of the axle of the angled portion of the wheel steering wheel force is transformed into a rotation force above.Depending on the direction and speed of the respective wheel, the final synthesis of these forces produces a resultant force vector in any desired direction to ensure that the platform can move freely in the direction of the final resultant force vector without changing the direction of the wheel itself . Many small rollers are distributed diagonally on its rim, so the wheels can slide laterally. The generatrix of the small roller is very special. When the wheel rotates around the fixed wheel mandrel, the envelope of each small roller is a cylindrical surface, so the wheel can roll forward continuously. The mecanum wheel has a compact structure and flexible movement, and is a very successful all-round wheel. There are 4 such new wheels combined, which can achieve a full range of mobility functions more flexibly and conveniently.On the other side is an introduction to the remote control and battery pack. It is understood that high-quality lithium battery packs, model aircraft locators, and USB ports for mobile phones are the reasons for the high cost of the product.Product and manufacturer information.【Contents】 There are 2 inner boxes. The boxes and patterns of different colors come out with a feeling of not simple.[Instruction manual, sticker] It is individually packaged and protected by cardboard at the bottom.【Instructions】 The steps are clear, but some parts do not display the 1: 1 icon, which is a bit inconvenient.Operating instructions for remote control.The last page is the parts list.The battery box and the remote control have separate instructions.【Sticker】 Patterns, printing, and cutting are of very high quality.【Parts package】 No steps to subcontract. And the color of the parts is small, so it is a bit difficult to find the parts.This is the soul part of this set! There are 2 kinds of specifications. Because it is not easy to identify, the manufacturer has pre-marked it to facilitate everyone’s assembly.【Motor unit】 There is independent packaging.There are battery box, motor x4, lighting, remote control and charging cable.Note that the interfaces are all mini USB, which is not compatible with mainstream interfaces.The speed of the motor feels a little faster than the average M motor.I have to mention that the texture of these electric parts is really great!My set is a deluxe version, so I give these small gifts【Assembly process】 This is also a soul part!The gimbal is pre-installed.The structure is completely uncomplicated and the principle is well understood. Compared with electric parts, the feel of the parts is only general, but the plugs are not tight, and it is very comfortable to put together.The sticker quality is really good!Finally, the assembly of the Mecanum wheel. I will soon know the actual performance of this set! Great expectations!There are so many spare parts …【Multi-faced photos of finished products】 In addition to the wheels, it feels ordinary in other places.I misspelled it …It was corrected in the end【Details】 Generally, the quality of the parts of the hole arm is average, and the plate is good. (But most of them are covered by stickers)Most of the wires are exposed at the bottom, and you can also make some fixed structures yourself.The interior is simple.The sticker on the door is so handsome!The door can of course be opened.The tail value is fully supported by stickers.【Operation Video】
Test drive …
Is n’t it fun? This wheel is so fun! Just need to be familiar with the operation, otherwise it will hit the wall as often as this video【to sum up】 The effect of this set of finished products is really good! This way of moving is so interesting! It also made me know nothing about what is the Mecanum wheel, and added knowledgeIn terms of parts, the quality is average, and the insertion feels good. But the level of power components is relatively high! Since the manufacturers’ products used to be export-oriented, and the parts are not compatible with mainstream building blocks, they are now entering the compatible field, so the quality of parts needs to continue to be adjusted.
