Vibe Coding Robotics Part 8 Built a hexapod simulator with Claude Opus 4.6 Based on an open source algorithm that works on real hexapod robots. UI design generated with Nano Banana. More details ↓

1. Instead of asking AI to write the algorithm from scratch, I wanted to see if Claude could take an existing hexapod algorithm from GitHub and implement it the way I wanted. I used Gemini in other parts, but from my testing, Claude works really well at transforming code from other repos, so I used Claude for this one.

2.This is the open source repo I used, created by Mithi Sevilla. (could not find them on X). I made a Next.js and shadcn version of this repo a couple of months ago while trying to understand the algorithm.

3. I copied code from one of my old robotics demos and from the hexapod repo into a single repo and used that as context for Claude. I asked it to reuse the algorithm from the original repo but build the visualization using techniques from my robotics demo.

4. The main difference is that the original repo uses Plotly, while I wanted to use three.js. That meant Claude had to write a whole new set of transform functions to convert data meant for Plotly into something usable in three.js.

5. I also asked Claude to convert everything it used from the original repo to TypeScript and to convert all classes into function based implementations. While I eventually reached a point with no TypeScript errors, I would call it a lazy conversion. React class components were converted to functional components successfully, but it struggled with classes in the core algorithm.

6. Overall, it did a good job and I got it working. I did have to review the code a few times and explain what went wrong when some fixes were clearly going nowhere.

7. Next time, I will probably try converting a simulation written in a language other than JS or TS to see what happens.

8. In case you missed it, here is the last part of the Vibe Coding Robotics series where I built Leonardo da Vinci's ornithopter.

9. I also have a series where I try to make games with AI. Here is the latest part of that series.

That's cool! Check what we built, with the same vision as eventually vibe coding robotics!

looks awesome!. love seeing more people exploring this space

Thank you, Same here, keep those awesome demos coming

jesus christ this is insane

haha, thanks Kitze

Stunning

thanks

Tachikoma here we come!

all hail the king of robotic simulators please don’t make a real version of this, it terrifies me

thanks 🤖 I may or may not have been eyeing some 3D printers recently 😉

This is super cool. Thanks for sharing. UI and animations are becoming more than ever important in distilling complexity.

thanks

Amazing. How do you go from the nano banana mock-up to code?

thanks. I attach the nano nanana image with the prompts and ask claude to implement it. If it misses parts, I add a screenshot of the specific section so it can focus on that part

I have been doing the same for mobile apps. I fully describe the UI styling so that all screens generated follow the same esthetics but it’s kinda hard when you have multiple screens and flows. I have to constantly be poking Claude to follow suit and then address somes differences

If you watch a spider's walk cycle you'll see that a limb will enter a state of 'traction seeking', where it will move that limb a few times in order to find a point of traction on a surface. I saw demos from nearly 10 years ago where a guy had done this algorithmically for procedural animation, and it looked really, really good. Talk this through with Claude and see where it gets you.

Claude excelled at transforming and implementing code.

i like your projects 🔥

thanks

Everything will be so easy, even hardware..🎉

bruhh. That's insane! Such a fun UI. We need to make software more fun

So cool. Never thought to vibe code the simulator.

thanks

Wow, this looks awesome

Developments in this space make me super optimistic

Stargate - Replicators .. that's all I'll say

good job

@occultist357 thanks

Not what Linus was wanting to be vibe coding, but this process may be interesting to @linusgsebastian, Luke, and @BuhDan. Vibe coding an interface for a robotics simulator off #GitHub, complete with UI generated from images. And no #ChatGPT in sight. 😜

I love the interface

Excellent!

😳Even though I’m not in this field, I couldn’t help but stop and analyze this work. It’s a perfect case study for the 'Bridge between Intent and Execution.' > This sparked a new direction for my upcoming AI Tests: How do we measure the 'reasoning depth' when an AI translates a high-level vibe into a complex kinematic system? 🤖🧠 This is more than coding; it’s a shift in cognitive architecture. Truly inspiring! 🪞🌙

Wow. Amazing.

thanks

Worth a follow

thanks Jimmy

lovely ui

this is dope man, can i get a hexapod as a pet? 😂

Ui is beautiful

thanks

Love it, how to get started ?

thanks. start with something simple. take an app you use every day and describe its features in prompts, then try to implement it. expect things to break. what you usually see online are the good outcomes, not the many failed tries

Suuuuper clean!

thanks

@DilumSanjaya, building a hexapod simulator with Claude Opus is a neat way to test robotics algorithms.

The IK solver looks incredibly stable. Getting a hexapod gait this smooth usually takes weeks of manual tweaking. Seeing it 'vibe coded' into existence is a massive flex for the workflow.

That's an impressive hexapod simulator! The UI design generated with Nano Banana looks great.

thanks Helder

Nice

Seen how this ends...
