A personal project last for 3 years and spent thousands of dollars.
This is a dream that I had for many years. 3 years ago, I finally decided to realize.
With improved algorithm, hardware and mechanism, plus special designed servos and linear motors, It can achieve high torque, high precision and high speed.
It still not reach the maximum speed because the cube couldn't stand it. I'm still working on that. But yet still, it is an awesome machine right.?
