Why did I created this robotic arm?
I've always dreamed of joining the amazing world of robotics and learning how to control hardware with code. As it turned out, this is an interesting, modern, developing and useful activity. Having mastered the basics of programming, you can make a lot of interesting and useful projects and turn an original idea into a real device.
There comes a time in everyone's life when they have to make their own manipulator. You must agree that it is always useful to have such a mechanism at home, because if two hands are missing, you can make yourself another one.
To study control algorithms and gain practical experience, I faced the task of designing, modeling and assembling a structure that can be classified as an anthropomorphic manipulator capable of approximating the movement of a human hand.
Initially, there was a plan to do something in the style of Cubism, but it was decided to partially abandon the idea.

This system cannot utilize continuous rotation servos, as they cannot control their position. The servo version with limited actuation rang (180° for the small ones, 180° or 270° for the big ones) must be used. This obviously limits the range of the robot.

Good for education & testing, bad for actual tasks & lifting things
