preface

With the continuous progress of science and technology, children's toys are no longer as low-end as we were at that time. More and more high-tech elements have been added to the toys, so that children's intelligence can be developed earlier Love to play computer games The platform has applied for a small card robot. I didn't have the luck to play such an interesting toy in my childhood. Today, I can play it to make up for a big loss in my childhood! Now let's have a look!

Unpacking

The packaging box of the small card robot does not look very exquisite. There are some cartoons, which may be seen from my eyes as an adult. For the yellow color matching of children, it should be more pleasant to print a small person's pattern.

"Making programming more interesting" is also marked on the side of the box, which shows that it is not simply a toy robot, and it has a big beginning!

The small truck robot adopts the component splicing method, which disperses the components and places them in the foam in the box.

The main components of the small card robot include: mainboard, line patrol sensor, frame, wheels, electricity, motor, etc.

The motherboard is the core component of the small card robot, which is equivalent to a human brain. We can see that the motherboard is densely covered with solder joints, connection interfaces, mode selection and power switches, and our power socket is also on the motherboard.

This is a transparent cover plate, which should be used to protect the motherboard.

The power supply here is powered by a 18650 battery, which is fixed with double-sided fluff glue.

The two motors drive the left and right wheels respectively.

Equipped with hexagonal wrench and screwdriver, etc., so that we can easily install without other things.

There are deep patterns on the two wheels, which can increase friction.

The frame is made of aluminum alloy, which is very hard. The holes and corners are well made, without any cutting touch.

This little thing is the line patrol sensor of the small card robot. With this small card, you can walk along the black path.

This thing like a steel ball is a universal wheel, which can let the small truck walk in all directions.

In addition, the small card has also attached a line patrol map. Put the small card robot on it, push the switch to the line patrol mode, and it can walk along the black line.

Now let's use the video to show you the assembly process of the small card:

user's experience:

After the installation is completed, we can download the APP to control the small card robot. The small card is connected to the mobile phone through Bluetooth. In the main interface of APP, there are sports mode, programming mode, and top speed car, etc.

In sports mode, we can control the movement of the small card in all directions through Bluetooth, which is no different from our traditional remote control.

The most classic is its programming mode. We can freely combine various instructions in the preset, and then start to walk in the preset order.

The following video shows you the various modes of the small card

Summary:

First of all, the small truck robot has a unique appearance, which is different from our general robots and robot cars. In addition, its metal body makes it particularly solid. The most commendable thing is its rich functions. Besides, each module is quite mature, and its sensitivity is very sensitive, which is worth playing.
