How many years have you been competing in in RCJ Soccer?

Four and more years

What’s the most interesting thing you’ve prepared for this year’s RoboCupJunior Soccer competition?

A 3D printer was used to create a motor mount with a three-dimensional structure that could not be made on a CNC machine.

Where can we find your poster?

It should be available at https://drive.google.com/file/d/1TykLQeLRh7lk8j9j6cssyBneg6PkL0iA/view?usp=sharing

Also, the team has prepared this video: https://youtu.be/p1JVRHjVRBs

If you’d like to know more, please feel free to ask @konoe_akitoshi by replying to this thread or check the team’s webiste/repository at https://sites.google.com/view/nt-rcj/ !

How did you make your mirror? It seems so smooth and well made.

The pioneer of mirror making in Japan is @yxtada (Twitter).
I copied his work, so you can read more about it in his blog(http://yunit.techblog.jp/archives/70016697.html).
However, they are not exactly the same, so here are the differences.
・I don’t use putty.
・I put plastic tape on the back of the mirror to eliminate the bumps.
・His is flat in the middle and mine is completely hyperbolic.
※Please use an electric stove. Stick the mirror sheet to the board!

Very nice poster and robots!
I have two questions:

  1. In the Design part you mention that “We reduced the number of switches in order to prevent robots from accidentally pressing a switch in a collision with each other”. What switches are you talking about?

  2. For the Image Processing, what type of camera and board did you use?

Thanks for the questions.

  1. switch = toggle switch in the control system (which affects the robot’s movement)
    ＞There are only two switches on this robot: a start switch and a goal switch.

2.We were using OpenMV H7 Cam.
＞Next year we are going to use the OpenMV H7 plus…

Congratulations on your progress!

I have only two questions:

  1. I’m curious about if your playing algorithms include opponents or teammate detection or collaboration.
  2. You wrote “The two robots are interchangeable and both have offensive and defensive powers. The offense has a strong dribbler and the kicker has agility and aggression. The defense has a large holding area and is very strong defensively.”. How are your robots interchangeable then? are you supposed to interchange the dribblers and holding areas? strength and agility are programmed?

Just came here to say that those LEDs in the video were a very nice touch.

Nicely done!

Thanks for the question.

  1. we couldn’t do it.
    (Reason [excuse])
    We were in the NIPPON league until last year. So we spent too much time controlling the dribbler and omni-wheels. (it was our first time making them)
    (Actually)
    If I was going to be able to go to the world championships, I was going to make improvements before then.
    (Future)
    Allows for inter-game communication using XBee and switching of offense and defense during a game.
    Realize detection of opposing robots by Tof sensors.

  2. I’m sure I didn’t explain it well enough. Sorry…
    Mostly for testing.
    There is no dribbler and kicker on the keeper, but the control board and the sensors used are the same. Is. Therefore, it can be replaced when it breaks. We can also test the attacker’s program in a keeper. (we only made two robots)

Thank you.
It uses Neopixcel.

I’m glad you found it because it’s actually an area I’m proud of.
