Devlog #2
Finished printing everything and started testing if everything fit together. Some of the components had weak spots or didn’t fit together well.
I had to go back and forth between CAD and printing for a while because my tolerances weren’t quite correct. Everything fits nicely now.
I also made a GitHub repo and added all the CAD files, BOM, pictures etc. I will update GitHub frequently, and everything needed to recreate this project will be there.
I also made a wiring diagram and in the process realized that I needed a few more components to make sure that the arm would work smoothly and safely.
I was kinda hard to learn why I needed all these different components but in the end I think it makes sense to me now.
The next steps now is probably to buy the components and then assemble the robot.
In the meantime though I think I can start writing some code on Inverse Kinematics for the Robot. I want it to be able to move all the servos to the correct angle when given some coordinates.

@Vedaprotoshredhq - if I want one on top of my hexapod/spider robot then how much lest weight this arm can be of, like the smallest possible version of this arm.
@Vedaprotoshredhq I made this arm to be quite big so the motors were quite heavy. All the servos combined is around 580g, 3d printed parts plus the ball bearings would be around 1050g. For a smaller design I think you can make the 3d printed parts smaller (~half as small, reducing the length mostly), although you would have to redesign the servo mounts. Im designing this arm to pick up around 1 - 1.5 kg, but if you want to cut some weight there you use smaller servo (minus ~200g)
okay thank you, I will ask for your help when I will make arm for the hexapod.
@Vedaprotoshredhq I made one that is 4 dof if you want you can check it out

@chahatesh - yes sure bro!
