frameworks?

[mbz4]

chat w/gpt: tried to think of how to integrate existing codebases with the rsc (complicated but perhaps a good idea?) alternative is we run our own codebase and only rely on external frameworks for non-core functionality (perhaps flutter or react for their mobile & web support)...

should succeed #2

I understand that you are looking for a scalable and flexible solution for your Robot Study Companion (RSC) and want to consider different technologies (ROS 2, ROS Micro, ESP32, Raspberry Pi Zero, mobile apps, Flutter, etc.) in various scenarios. Below is a comprehensive table that outlines the different technologies and the scenarios they support, comparing their flexibility, scalability, and ease of use for both developers and end-users.

Analysis of Technologies:

1. ROS 2 on Raspberry Pi 3/4:

• Best For: Full-scale robotics applications, distributed systems, and real-time control. Ideal when you have enough resources on the Raspberry Pi 3/4 and need scalability for adding sensors, actuators, and other robots.
• Flexibility & Scalability: High, as ROS 2 supports complex setups and allows easy scaling by adding additional nodes or devices. Suitable for professional and scalable robotics applications.
• Drawbacks: Requires more technical setup and is harder for non-expert users to manage.

2. ROS Micro on ESP32/Pi Zero:

• Best For: Low-resource, low-power tasks where a full ROS 2 stack is not necessary. This setup is great for embedded systems with limited computational power.
• Flexibility & Scalability: Lower than full ROS 2, but allows basic robotics control. It’s ideal for very lightweight tasks, but not for more complex applications that require real-time processing or large amounts of data.
• Drawbacks: Limited capabilities compared to full ROS 2. Only suitable for simple control tasks.

3. Full ROS 2 on Laptop + ROS Micro on ESP32/Pi Zero:

• Best For: Distributed systems where you offload processing to a powerful central system (like a laptop) but have embedded nodes on low-resource devices.
• Flexibility & Scalability: High, as you get the best of both worlds—powerful processing for intensive tasks on a laptop and lightweight embedded nodes for basic control.
• Drawbacks: Setup complexity is high, and it’s not user-friendly for laymen. Managing multiple systems may require significant technical knowledge.

4. Flutter App for Mobile + ROS Micro on ESP32/Pi Zero:

• Best For: User-friendly control of embedded robotics from a mobile interface. This approach simplifies the user interaction by using a mobile app while leveraging lightweight embedded devices.
• Flexibility & Scalability: Medium to high. Flutter provides a flexible mobile interface, but you’re limited to basic interactions with ROS Micro, and scaling is limited by the embedded hardware.
• Drawbacks: Bridging between Flutter and ROS Micro might require custom solutions and middleware, which increases development complexity.

5. Flutter App for Mobile + Full ROS 2 on Raspberry Pi 3/4:

• Best For: When you want a fully featured robotics system with real-time processing and control via a mobile interface. Combines the power of ROS 2 and a user-friendly mobile app interface.
• Flexibility & Scalability: High. Full ROS 2 is scalable, and Flutter allows easy control from mobile devices.
• Drawbacks: Development complexity is higher because you need to bridge Flutter with the ROS 2 ecosystem.

6. Custom Embedded Stack on ESP32/Pi Zero + Flutter:

• Best For: Highly specific robotics control where a custom solution is needed. You can create a very specialized system that interacts with a mobile app, but without the overhead of ROS.
• Flexibility & Scalability: High on the customization side, but limited by the hardware’s power. More flexible for certain niche tasks but not as scalable as ROS.
• Drawbacks: Custom embedded stacks require more development effort and expertise in embedded systems.

7. Custom Embedded Stack on Raspberry Pi 3/4 + Web App (Locally Hosted):

• Best For: Simple setups where everything is contained on a Raspberry Pi and accessible via a local web interface. This could be ideal for isolated environments with no need for cloud connectivity.
• Flexibility & Scalability: Medium. Easy for users, but limited by the Raspberry Pi’s computational power and network access.
• Drawbacks: Not scalable beyond a local network and harder to expand.

8. ROS Micro + Web App (Locally Hosted on ESP32):

• Best For: Basic robotics control via a web interface on very low-resource devices. Good for educational or low-power scenarios.
• Flexibility & Scalability: Low, as ESP32 has limited resources. Ideal for small-scale robotics or IoT applications.
• Drawbacks: Limited to very basic tasks and low scalability.

9. ROS 2 on Raspberry Pi 3/4 + Web App (Locally Hosted on Pi):

• Best For: A robust robotics system with a local web interface. It provides scalability and ease of access while being self-contained on the Raspberry Pi.
• Flexibility & Scalability: Medium to High, as ROS 2 offers scalability, but the Pi’s resources can be limiting.
• Drawbacks: Requires some setup and could be limited by the Pi’s hardware if tasks become too complex.

Conclusion:

• For full flexibility and scalability, a ROS 2 system on a Raspberry Pi 3/4 with either a Flutter app for mobile or a locally hosted web interface offers the best combination.
• For lower-resource setups (like using ESP32 or Pi Zero), consider ROS Micro with either a mobile app or custom embedded stack. If users are non-technical, a Flutter app might be the best way to bridge the gap between embedded systems and ease of use.

tried to think with gpt on possible ways of approaching developing the rsc and assure high flexibility and scalability... ie, iotempower relies on multiple stacks incl node.js
in our case we have the agenda of having multiplatform crossoperations (I guess local area network only) and limited dev time and resources but need neat and tidy, scalable solutions

example: maintain separate codebase for the esp32, pi zero, pi 3/4/5, mobile app
counterexample: maintain 1 codebase for the esp32, pi zero, pi 3/4/5, mobile app

then suppose you want to run ROS(2) on the RSC/laptop ==> now we have a laptop in the mix, too

so the conclusion venn diagram suggests flutter (has mobile and web support, works on arm and x86) together with ROS (1/2 and Micro if not going for bespoke embedded stack (iotempower?))
of course the core features of the rsc would have to be built first for a proof of concept, ready for evaluation... since this kit doesn't touch on ollama or similar frameworks that would also have to be embedded or LAN reachable...

[mbz4]

noticed gpt omitted react, vue, nuxt/next.js

but that's not so important: more crucially - need to push core functionality out soon and regroup on what we learned and how to support adding new features with no overhead
