I’m a robot lover¶

Hi! My name is Jason and I’m an IT support staff in CMA Secondary School in Hong Kong.

Also, I am a maker and founder of the Jason Workshop. That is a small studio whose goal is to make everyone’s life better through my work!

My previous work¶

My final project idea¶

█ Why

I have always designed Bionic Quadruped Robot and fascinated by this subject for many years. I learned a lot and had a lot of fun from robot.

So I want to design a robot for a STEAM course to arouse students’ interest in making robots and promote maker culture.

And I would like to share some old works here and hope you can feel my passion and love for Quadruped Robot.

█ Purpose

The purpose of my final project is not only to design and make a quadruped robot, I plan to write down the design concept and production method of robot into the assembly handbook, and publish to the world as open-source. Hoping to let more people in different places can get fun from it.

█ The final product

Q1 fab simple bionic quadruped robot 3D source file
Offerical website to promote Q1 fab
All resource will store in GitHub

Research¶

I usually go to different design websites such as Pinterest to observe other people’s designs, understand their design concepts, the mechanical structure of the robot, electronic parts, and how to code.

█ Summarize

I set the following conditions for my robot

It’s easy to prepare and assemble, suitable for robot beginners and academy
Simple design, easy to produce by 3D printer
Print all 3D parts less than 24 hrs
8 DOF
Angle feed back 讓編寫機械人動作更輕鬆
Fully self-produce control board
Compatible with Arduino IDE
Less text and most picture assembly instruction to reduce language barriers
Affordable

Material¶

What materials and components will be used? Where will they come from? How much will they cost? What parts and systems were made?¶

The materials that I used in my final project mostly purchased by Taobao. For some of the raw materials (Copper Plate and electronic parts) provided by FabLab iSpace

█ Q1 fab sumo game arena

Item	Quantity	Source	Costs (USD)
11mm MDF board 600mm x 600mm	1	FabLab iSpace	$6
Spray paint	1	Material store	$6
Silicone ｜ 2	FabLab iSpace	$4

Total costs of my project is USD$50.1

█ Special modification allows the MG90s servo provide angle feedback function, If you think it is too difficult, you can use normal MG90s servo, just angle feed back function will missing, it will not affect the main function of Q1 fab.
