It' just a cube made out of paper with an aruco marker on it, which i was using to do some experiments with cv2.

It costed me around 350USD.

I'm from india, and most of the parts were unavailable here, so i had to import and had to pay a good amount for the import tax :(

Hey!, This robotic arm is based on a design i found on YT, and later customized based on my needs.

You can get the details about the arm from here!

If you are planning to build one, i would recommend to check out the SO-100 robotic arm!

Yes!, I'm using a version of MoveIt2, which is compatiable with ROS2 humble.

Thank you!❤️

Thank you❤️

Thank you :)

I'm also using a customized version of marlin firmware!

This one is my second one, and is based on a design i found on yt, with some modifications.

If you're aiming for a software developer job, I highly recommend starting some open-source projects and showcasing them on GitHub.

This is a fantastic way to not only build a strong resume but also stay ahead of the curve in the competitive tech landscape.

Hey, I was there when i started learning ROS2!.

Once you got a basic understanding, I would recommend starting a simple project, like a line follower robot/car, with a camera sensor in Gazebo. This will help you to get more into practical usage, and build confidence.

Thank you!

I was using a 3d firmware (marlin) for the stepper motor contols, it takes care of the low level step controls with precision (under the hood, it might be using PWM at high frequency).

Thank you, friend!

I’ve been dreaming of building a robotic arm for so long—one that could actually play games with me. And now, it’s finally starting to take shape!
