What will it do?¶
I want to design a quadruped robot for a STEAM course to arouse students’ interest in making robots and promote maker culture.
I set the following conditions for the 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
- Servo angle feed back
- Fully self-produce control board
- Compatible with Arduino IDE
- Less text and most picture assembly instruction to reduce language barriers
- Affordable
Who has done what beforehand?¶
I search some key words (Fab Academy, Final project, Quadruped). There are no exectly the same final prject done before.
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.
What will you design?¶
The designs that will be included in this project are
- Robot logo design (Affinity Designer)
- Robot 3D printed parts (Fusion 360)
- ESP32 control board PCB (Fusion 360)
- Programming (Arduino IDE)
- Instruction book (Keynote)
- Published on Internet as open source project
What materials and components will be used? Where will they come from? How much will they cost?¶
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

Total costs of my project is USD$35.1
I what parts and systems will be made? What processes will be used?¶
Mechanical system of my project
- The logo will be use sticker for sticking on my final project and cut by Vinyl Cutter - Brother ScanNCut SDX1200.
- The main body and mechanism of robot designed in Fusion 360 and print it by 3D printer - Creality Ender-3 Pro
Electrical system of my project
- The PCB produced in CNC engraving machine - Roland Modela Pro MDX-500
- Adding servo angle feed back sensor (Input device) and servo moter (Output device)
Text and open source archives
- All project file store in github repository and have version control
What questions need to be answered?¶
My main concern is the robot can be easily printed and assembled. In the design, it is necessary to meet the limitations of 3D printing, and also to simplify the steps and difficulty of assembly.
In addition, the instructions book need most pictures and few words as possible, easier to promote this project around the world.
Finaly, I need to build a mini web server and host a web-based control interface in ESP32, this will make operation easier.
How will it be evaluated?¶
- Does the quadruped robot can be perform some action.
- All file can download from published website.
