LewanSoul xArm Robot Arm #3 : Mechanical Build Completed

26 Feb 2019

I have now completed the mechanical build of the LewanSoul xArm Robotic Arm. Apart from a few quirky bits in the video (only) construction guide I was able to put the whole arm without too much difficulty. There are still a few aspects that I am not sure about but I assume these will be sorted out during the wiring and calibration processes, which are the next steps.

So far it has all been good and seems well worth the money that I spent on it.

And for me I need a magnifying glass to see them!

I must admit to having difficulty with such small nuts, as I have biggish fingers which seem to work less well with small things with every passing year. I just preserver until eventually I can get the nuts on. I used to use 2 mm nuts and bolts with the SG90 micro servos which was very difficult, but now I just use 2.5 bolts and these self thread into the mounting holes. So far this has worked really well.

I Found the m2 bolts and nuts nearly impossible to work with. Suggested to them standardizing on m2.5 or m3.

Dab,

Counter weights are a possibility but it might be a problem trying to work out where to put them as there quite a few possible degrees of freedom so sometimes a counter weight might be needed and then with other configurations it wouldn't. Plus the weight of the object being moved will have an impact as well.

Good build.

You might consider some counter weights if you feel you need to ensure a steady movement under load.
