Long time not to appear , I suppose no one like to research such thing except me !
So how to control arm bot from computer side ? ( arm bot installed Servo or Stepper ) ,
I don’t like to use Arduino #C , because it is really hard and complicated . At last I feel Grasshopper + Firely is the best .
In the beginning I use Servo , it is pretty easy , just the Servo is too poor , it is not accurate at all . Here is the video .
Another video .
But when start to write ,it is poor looking , because the Servo is too poor .
So at last I try to use Stepper to try , here is the 1st stepper to test in Grasshopper firefly .
Then I install it on my arm bot , For cost reason (Actually it is because of my poor wallet) , I use 28BYJ , the smallest and cheapest one .
First test after installation , notice I have revised the stepper motor by manual , it is tough looking . haha~
But at the beginning , there is a big issue , and I almost give up !
it is lucky that I resolve it . Here is another success small video.
Wow , is that smooth moving ? let’s zoom it out !
I spend some months to make such thing , it is really waste time , but I love this hand-working-and-research .
Upload this article , just hopes the world won’t forget my efforts .
