Show HN: Stack-chan – Open-source companion robot easy to assemble and customize

76 points by meganetaaan 4y ago

Introducing Stack-chan, an open-source hardware robot designed with Fusion360 and Kicad that is easy to assemble and customize. With just 6 screws, you can easily put together the robot and add your own features using JavaScript with the Moddable SDK. Stack-chan is completely open-source and the design files, firmware and software are all available on GitHub repository (https://github.com/meganetaaan/stack-chan https://github.com/meganetaaan/stack-chan) . Give it a try and customize it to your needs. We'd love to see what you create and hear your feedback on this open-source project.

Very cute, but I wouldn't know where to start.

Thanks for your comment. I am currently working on a Getting Started guide and hardware kit to help people with no electronics experience get started. There are several options for getting Stack Chan hardware. Option 1: Kits. You can get started by purchasing a third-party kit (https://mongonta.booth.pm/ https://mongonta.booth.pm/ ). This kit uses a breadboard and wires to assemble the dedicated circuit board instead of soldering it together. Another user illustrated instruction article (https://note.com/sylacwa/n/ne58704a19110 https://note.com/sylacwa/n/ne58704a19110) is also available. Option 2: Personalized manufacturing services. JLCPCB (https://jlcpcb.com/ https://jlcpcb.com/) offers 3D printing services and board fabrication/assembly services. Data for Stack-chan boards (https://github.com/meganetaaan/stack-chan/tree/dev/v1.0/schematics/m5-pantilt https://github.com/meganetaaan/stack-chan/tree/dev/v1.0/sche...) and cases (https://github.com/ https://github.com/ meganetaaan/stack-chan/tree/dev/v1.0/case) are in a format that can be ordered directly from JLCPCB.

  So option 1 allows me to have a small little robot without any soldering? Nonetheless, awesome work!
  - mongonta555 4y ago
    Yes. 1 kit can be used to make this small robot if you have the following items. ・M5StackCore2 ・SG90Servo x 2pcs ・M3x18mm Screw x 2pcs ・M3x20mm Screw x 2pcs

      Sweet!! I ordered one(tho I live in Europe) and waiting for it to arrive. Meanwhile I can Google places where I can buy the order pieces. Thank you!

This is really cool, bookmarked it will check back to see if the pre-assembled module becomes available. Don't feel like building it myself

  Thanks. I am planning to sell the kit. https://hackaday.io/project/181344-stack-chan-javascript-driven-super-kawaii-robot/log/208937-beggining-commercialization-for-stack-chan https://hackaday.io/project/181344-stack-chan-javascript-dri... Not soon, but not far off. I hope you will look forward to it. And third-party kits are already available. Please refer to the comments above.

This video is a bit more informative (IMO) than the one linked in the readme, even if you don’t understand Japanese: https://youtu.be/fZb_mF08xV0 https://youtu.be/fZb_mF08xV0
- meganetaaan 4y ago
  I updated the link on the readme. FWIW the video has English subtitles. Hope you enable then watch it.

A little more info that I didn't include in the post. Did you know that more than 150 Makers have already started building Stack-chan with kits or their own creations? We frequently publish the results of our development on Twitter under the #stackchan tag. https://twitter.com/search?q=%23stackchan%20OR%20%23%EF%BD%BD%EF%BE%80%EF%BD%AF%EF%BD%B8%EF%BE%81%EF%BD%AC%EF%BE%9D https://twitter.com/search?q=%23stackchan%20OR%20%23%EF%BD%B... I've written a detailed explanation of the motivation behind the development on my Hackaday works page, and the Logs page contains not only my development records, but also examples of hacks by community members. https://hackaday.io/project/181344-stack-chan-javascript-driven-super-kawaii-robot https://hackaday.io/project/181344-stack-chan-javascript-dri...

I was just thinking "very cute, but needs a killer application", then found this: https://www.youtube.com/watch?v=SZ9zfOWTXQc https://www.youtube.com/watch?v=SZ9zfOWTXQc What could be more badass than a ...uh ...tracked tamagotchi for office warfare? Just add a Dalek voice ("exterminaaate!") and it's perfect!:^)

  I made it. I packed unique technology into it to play desktop warfare in a fun way. (For example, home-made infrared protocol to measure shooting distance, torque limiter for servo protection, sound, light, and vibration effects, etc.) There is not yet the ability to track while saying "exterminaaate!"

Okay, there is Stack-chan wearing Chebyshev Linkage walker unit. He is armed with rubber band guns. It looks awesome strong! :p https://youtu.be/heL2X7JFNkg https://youtu.be/heL2X7JFNkg
