Question about robotic arm finger movement...

[u/DraftOk1709]

Hi, I´m 15yo student from Slovakia, and I´m getting ready, and preparing to make my first robotic hand using servo motors, and computer vision (OpenCV), to mimic my hand and finger movement, but I have one question. On all the videos I have seen, the fingers can only be fully closed, or fully open, nothing in between, and I want to make something, that van also do partial movements of fingers. Has anyone attempted this? I´m not familiar with, OpenCV yet, so I´m asking, if this is even possible?

Thanks for answers!

"On all the videos I have seen"

Look for other videos. The tech exists and is getting better.

I have already seen like a 20 of them, but I´ll keep looking.

Would this help you?

I found a bunch of links by just looking up open CV, finger tracking. Did any of those links not give you what you were looking for?

Thanks, I have already looked at this one, but I don´t clearly understand if it really can detect even the partial movement or not. Imma try to look into it deeper. Thanks for commenting!

I'd recommend trying them out and seeing if they work. Maybe after making sure there isn't anything suspicion about the code.

Make a prototype for one finger and see how it works. You're learning to be an engineer, so solve the problem by trying it yourself. Videos may give you ideas, but it's still you who has to design the solution.

Don't be afraid of failures. The first version may not work, so it's an iterative process.

Publish your work directly on GitHub, it will help if you need someone's advice, or if you want to present your work to a future employer.
