My impression in contest in this year【original mouse】

Hello, my name is Eita. In this article,
I would like to refer ” my impression contest in this year”.

I will describe for person who worry like ” I’d like to make original mouse. ”

and ” I’d like to learn other person’s robot ”

My achievement is below.

2019　Kansai Contest 　PiCo part　Winner
2019　Kansai Contest　Classic Competition     retire
2020　Student Contest　　　Classic Competition     retire
2021　All Japan Championship　　Classic Competition　retire

Everything is in Japan.(>_<)
There are a lot of “retire ” anyway. I try to tell you my robot’s information(^^)/

1. “Movie of run” and “CAD data”
2. Information of electronic data
3. My impression of hardware
4. My impression of software

“Movie of run” and “CAD data”

こんにちはえいたです！
全日本マイクロマウス大会は
5走すべてリタイアでした(>_<)
しかし自作マウスが自立して
ここまで進化させれたことに
達成感があります(*’▽’)
来年度の大会で必ずリベンジします! pic.twitter.com/RByZWn2grN

Information of electronic parts

You know, I used only IC of motordriver in the past.
But I changed from IC to Aggregation of motordriver. I worry about this sentence. I don’t know how to tell that(>_<)
Anyway see this article 「モータドライバが再び故障」

My robot’s circuit diagram is below.
Elder student made this design. Then I changed a little bit thing around.

I already got permission to open this. This is from kicad.

My impression of hardware

List of impression

• To get elder person’s circuit diagram①
• To charge lipo battery frequently
  On the other hand, It is good to make “inspection program”
• To make 3D data in the kicad②
• To set capacitor(0.1μF) around motordriver
• position between serial pin and other electronic parts③
• To guess something accident
• To do everything in prototyping board, Then you can order your pcb borad④
• Don’t mistake between position of motor pin like ＋or －
• Try to make little robot as soon as possible
• To set gyro sensor in DC mouse or robot⑤

①Some people don’t have knowledge of circuit diagram. If you try to learn this topic, you need to spend much times due to do that absolutely. Could you get somebody’s circuit diagram? That is absolutely easy to make it.

②If  you use kicad, I would like to make electronic design of 3D data in fusion360 as well.
③Also, check usb entrance around. Because, Something might be around. If it might be true, you can’t connect between robot and pc (>_<)
(In my case, I have done. So, I needed to move my micro computer a little bit when I try to send information of program through the usb plug.)
④To try to test between Aggregation of electronic component

⑤Accroding to Japanese elder student, DC mouse which has gyro sensor is very common. You can do any “Calculus” used gyro.
I didn’t know this information. That’s why I didn’t set gyro sensor in my mouse.

My impression of software

教訓一覧

• You need to substitute right bit length to TGR ①
• Don’t make program like divide between file②
• The program which makes mouse stop is not graph like vertical axis of TGR and horizontal axis of “t(s)”.
  Make graph like vertical axis of rpm and horizontal axis of “t(s)”
• It is difficult used only LED and encoder in the Control engineering and DC mouse.
• Don’t praise mouse.③

①There are many cases like substituting right bit length to TGR in the RX631.
You need to put 16 digit in Binary number. This information is from hardware book of RX.

②Do you know this information? I would like you to not do that used ” extern “. If you do, then you will be confusing like “Where is program of run” and “There is not error on the program. But movement of mouse is crazy.” If you do, just be careful.
③This is Japanese rumor. Don’t worry about it(*’▽’)
If somebody praise mouse when it is running, movement suddenly change sometimes.

Impression in this year

Micromouse is competition of software. But I have concentrated hardware.
Because, I have spent much time in motordriver accident.

Overall
