DIY Workshop | XinCheJian DIY

The DIY Workshop mainly provides works created by XinCheJian members. Through this platform, you can understand the principles behind the works of XinCheJian members and DIY them yourself. On the other hand, you can also purchase corresponding works and kits at reasonable prices. We guarantee that all published works come from XinCheJian members, and we do not accept any commercial works!

XinCheJian DIY is a platform to showcase XinCheJian members’ projects. At the same time, people interested can buy DIY kits or projects directly through this platform at a reasonable price. We guarantee that this is not a platform that accepts all products. All projects must come from XinCheJian members!

This Week’s Recommendation: Otto Robot | This week recommendation: Otto Robot

DIY Otto Robot: A Fun Project for KidsOTTO is an interactive robot made using 3D printing technology for children.

Children can assemble it into their favorite shapes. Since its program is open-source, children can also program it, and while creating different movements for Otto, they can explore the fun and mysteries of programming!

By inputting existing programs, Otto can now walk, dance, sing, and more, and it can avoid obstacles using ultrasonic sensors.

It is a robot that truly helps children develop their hands-on and cognitive skills while playing.

This project comes from XinCheJian member Camilo, who, as a toy designer, truly understands how to combine toys with children’s imagination and education. Upholding the spirit of open-source makers, he is willing to share the process of creating Otto with everyone.

How to Make Otto:

1. Otto Component List

1. Arduino controller (Arduino Nano microcontroller)

2. Arduino expansion board (Arduino NANO Shield I/O Extension Board Expansion XD-212)
3. USB data cable (most Arduino kits come with this)
4. HC-SR04 ultrasonic sensor (HC-SR04 Ultrasound sensor)
5. 4 servos (Mini servo SG90 9g), each servo should be equipped with 2 pointed screws and 1 small screw.
6. 5V buzzer
7. 6 female-to-female breadboard jumper wires (Female to Female breadboard connectors cable, 10cm)
8. AA battery holder
9. 4 AA batteries (1.5V)

10. Cross screwdriver, preferably magnetized.

11. Ultrasonic sensor

12. Pointed screws, short screws

13. 3D printed head, body, two legs, left and right feet
Optional: Soldering iron (needed if you want to install the battery)

2. 3D Printing Settings for the Shell
Set the following parameters:
1. Use PLA material for 3D printing.
2. No support needed during printing.
3. Printing accuracy: 0.15 mm
4. Fill rate: 20%
You can freely choose colors and print the parts one by one. Or print them all at once (minimum printer size requirement: 14cm x 14cm).
