old work old tidy up

I’ll share the production process, but I strongly don’t recommend making it yourself.

Introduction

I believe that many of the students here have played Arknights, a two-spined salamander mobile tower defense game. The world view revolves around "Rhodes Island", and this is the prototype of Rhodes Island (referring to the cover)

Although there is no official description of this behemoth, the content is purely based on my personal imagination.

Modeling

There are only 5 official renderings of the appearance of Rhode Island, but I still drew the entire model with my own random imagination.

Using C4D modeling is relatively fast, but if you use professional industrial modeling software, it may take longer.

There are also attachments to the modeling files, which you can take a look at.

The parts need to be disassembled from the model, and then they can be 3D printed.

The entire structure took 2 months to complete, which was indeed a bit much.

PCB

The power part directly uses three lithium batteries connected in series to 12V, so a charging circuit is required. This is a three-cell lithium battery charging circuit in series that I have made before. If you are interested, you can check it out:

Because the voltage is 12V, it cannot be used directly for the main control, so a voltage step-down part is needed to reduce it to 5V for the lighting and MCU.

Directly used a very commonly used LM2596

There is also a 5V motor which is actually a redundant design and can actually be removed.

I just painted it all and am too lazy to change the layout.

The driving part directly used an L298N to drive the whole vehicle.

I was lazy in the main control part. I took a ready-made MEGA2560 motherboard and put it on the motherboard.

The remote control part uses the ps2 remote control on tb, and the code is also modified based on this.

It should be noted that the remote control receiver cannot be directly connected to the motherboard, and must be plugged in using a wire.

There are also some miscellaneous interface circuits that I won’t talk about.

Color

Apply casually

Assemble

Fight as you like

program

Write based on interface and function. . .

Anyway, the program has been released, I am too lazy to describe it - -

Finally, don’t forget to assemble and connect the lights. The lights will still look beautiful after being connected.

The lights actually have PWM dimming and are very beautiful at night.

It is driven by L298N, so the speed of the left and right wheels can be adjusted, and the steering is also differential steering. It is slower in the video because it is driven slower, but it is actually very fast)

There are still many functions not shown, you can go to station B to see the original video, I am too lazy to move)
