In Japan, we have the culture of
mascot costume as well as cosplay.
Some city have their own local
mascots.
I joined on-line event of local
mascots.
I wore a robot costume and introduced
the robots I made.
I will join some on-line events in
June.
I might have some live streaming at
Maker Faire Galicia and Maker Faire
Hannover.
The URL will be published later.

Music Derby is a game in which sound
of music runs seven robots.
The player predicts which robot will
go the farthest when a tune is over.
A single pitch is assigned to each of
the four-legged walking robots that
imitate animals such as deer, rabbits,
and mice.
For example, the note C is assigned to
deer, the note D is assigned to
rabbits, and note E is assigned to
mice.
When the note G is played, the pig
moves forward.
When the note F is played, the giraffe
moves forward,
and when the note E is played, the
mouse moves forward.
If twinkle twinkle little star is
played in C major key, which animal
will go the farthest at the end of the
song?
In C major, C is the tonic note, so
you might expect that the deer
assigned to C goes the farthest.
But in reality, the pig assigned to G
wins.
This is because G appears most
frequently on twinkle twinkle little
star.
On the contrary, the cat never moves
because B never appears.
In this way, Music Derby can visualize
the frequency of occurrence of notes
on the scale in a song.
The microphone picks up the sound
played by the instrument.
Analyze the pitch with Arduino.
Rotate the motor to move the animal
forward.
I tested pitch detection system with
various musical instruments.
Keyboard type harmonica is not bad but
missed some notes such as F.
Metallophone and toy piano have good
reaction.
12 string guitar is not good, contrary
to expectations.
Voice is not good, but it might be
used with some tuning, I guess.
Maybe I need voice training also.
Recorder is the best instrument for
pitch detection.
I think it's because it doesn't
contain much harmonics.

Robot Band and Tatami musical
instruments appears at 7pm Sunday

The Maker Music Festival seems to be
fairly well prepared.
It's an online version of what's
happening every year in California,
but it feels like it was planned
online from the beginning.
There are several virtual buildings
for each theme in the venue, and they
have virtual booths for each
exhibitor.
The robot band has a room in the
building called "TAKEMITSU" of 108.

関西コミティアは中止になりました。
コミケ系のイベントはメイカーイベントに比べて隣の出展者との距離が近いので、参加をみあわせる方向で考えていましたが、イベントが中止になりました。
全国的には5000人未満OKみたいですが、大阪府のルールでNGということのようです。
民博の音楽の祭日も無観客ライブが中止になり、事前収録の動画配信のみになりました。やろうと思えば出来たはずですが、国営なので判断が厳しめなのでしょう。
これからオンラインイベントにシフトしていくなら、自宅にユーチューバーのような配信ルームを作ったほうがいいかなと考えています。
