How about [youtuasi]
[youtuasi] is a Desktop Quadruped Robot.
With four legs creature = you.tu.a.si (in Japanese)
Summary
This is desktop Quadruped Robot call to youtuashi(yo.tu.a.si).
Use Arduino Nano and SG90 or Clone Servo Motor x8.
Only 9 Print Parts 8 DOF smaller 4 legs robot.
Easy make and Easy play about 3Days.
Day1: Buy the parts from Amazon or other store.
Day2: 3D Print and Make. (no soldering)
Day3: Compile and Run for Arduino IDE.
Total 6 hours.
Basic Model (Arduino Nano) front view like a crab.
GR-LYCHEE Model for AI and Image processing test bed front view like an octopus.
rotation model side view. like a piglet.

How to Make
- Printed 9 parts for your own 3D printer.
- Arduino fixed M3x15mm plastic bolt and nut with spacer .
- SG90 Servo motor fixed body and legs with M2x10mm screw..
- Joint and Servohone fixed M2x4mm screw
- Set Joint to Servo motor.(unfixed)
- Download and write sketch and set the basic position.
- Fixed Servo hone with M2x6mm screw
Software
Download and Open for Arduino IDE 1.8.5. or later.
And Write for Arduino Nano.

2.youtuasiTest.zip
youtuasiTest.zip is 「youtuasi」motion test sketch.
youtuasiTest.ino is robot controler for Arduino IDE serial console.
RUN
Open serial monitor 9600bps and Input numeric.
ex serial console
a,90,90,90,90,90,90,90,90 [Enter]
[ youtuasi] is basic position.
If no match youtuasiTest[1].jpg and your robot legs,you gona check servo motor hone angle.
The motion check are ended, you will write into the sketch, "case" between "break".
ex
case o:
set8pos( 90,90,90,90,90,90,90,90 ); delay(300);
break;

Key Feature
・Minimam size designed ( 80mmx150mm for minimal. 150mmx200mm for open. mass 220g include batteriess)
・Easy make (No Solderling and 6mm )
・Cantilever joint(Light weight and high speed)
・Compatibility SG90 Or Clone
・Adapted Arduino Nano Expantion Shild(No Solderling)
(or Arduino UNO and Akizuki D-type univasal bord with Soldering)
・Software Compatible for many Quadraped Robot pionears in Arduino comunity.
Option
Top cover or under cover are made yourself for 3D printer.
Claw or Hoof are made yourself, and atach to legs use M2 bolt and nut.
Arduino Nano A0 to A7 are open for set the own sensors.
Arduino Nano D10-D13 are open for exstra servo motors.

How I Designed This
In Japan Quadruped Robot are not major.
Robots image in Japan is wheel or two legs.
but two legs robots are so difficult to make and expensive.
then I modeling Quadruped Robot between two.
