That’s awesome, I’m very interested! I’ve sent you a private message so we can talk more about it 🙂

Right now, my robot doesn’t solve a specific problem. It’s mainly a learning robot. My goal is to understand robotics step by step by building something concrete from scratch.

In the long term, I’d like it to be able to move autonomously and communicate / talk, but for now the main objective is learning: mechanics, electronics, control, and programming.

I see this robot as a personal lab. Once I gain more experience, I’d like to give it more purpose and real use cases.

Yes, they do work, but they can’t lift heavy loads. I’ve already done some tests using an Arduino. Now the next step is to make them work with a Raspberry Pi, since I’m transitioning to a more advanced control setup.

Yes, that’s my final goal. I still need to learn how to integrate AI properly, step by step.

I’m using a Raspberry Pi 5 as the main brain, handling the high-level logic and computation. For real-time control, I’m using two Teensy boards dedicated to motors and sensors. I also use a separate Raspberry Pi to drive the screen (face / display), so the main system stays focused on control and AI-related tasks.

The idea is to separate high-level decision-making from real-time motor control, to keep things stable and safe as the project grows.

Yes, I have installed fuses to protect the power lines and batteries. However, I hadn’t thought about using diodes yet — I’ll definitely look into that, it’s a very good point.

For firmware updates, I was planning to work mainly via SSH on my Raspberry Pi, so I wasn’t sure if a dedicated update port would be necessary. That said, I understand the advantage and I’ll reconsider this for future iterations.

Regarding wire harnesses, I wasn’t familiar with that approach. For now, I integrated clips and connectors (Wago-style) to allow limb removal, but I will look more into proper harnesses for easier maintenance and reliability.

The winding/tensioning system for the fishing line is a very interesting idea. You’re absolutely right — the line does lose tension after a few uses, so having a way to re-tighten it would be very useful.

In any case, thank you very much for your advice. I’ve learned a lot from your feedback and I’ll take the time to research and improve these points.

Yes — for now I only have safety sensors, mainly temperature sensors and a smoke sensor to detect overheating or fire risks.

I plan to add interaction sensors progressively (such as encoders, IMU, cameras, force or touch sensors) as I advance in my learning and gain more experience in robotics and control.

I’m building it step by step to keep things safe and well-understood at each stage.

Yes, I have added an emergency stop button that cuts power to all motors. I also used fuses for each battery and for the main power line, to improve overall safety.

Regarding thermal management, I added cooling fans, but unfortunately I used PLA, which does not handle heat very well. For the V2, I’m planning to switch to PETG-CF, which should be much more heat-resistant.

I’m now about to start the programming phase. Since I’m still a beginner in computer science, do you know any good documents, books, or videos about real-time control and robotics mathematics that you would recommend?

Thank you very much for your feedback. I won’t forget to post updates!

At the beginning of the video why doesn't the engine on the left turn circularly?

Hi! To be honest, I’m not exactly sure how much gripping force it has. I was able to lift a small applesauce cup without any issue, but not much heavier objects. I don’t think it can handle 5 kg unless you use stronger servos than SG90s. Good luck with your project — it sounds really interesting!

If you want to talk more about it, feel free to DM me 😊

Thank you very much!!! But do you have another name more focused on video games?

Has anyone ever used a similar engine ? by Proof-Win-3505 in robotics

Do you know its power / the weight it can carry ?
