[Video] Use Grasshopper Firefly to connect Servo or Stepper motor

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 .

  1. Great job!! you can be sure you are not the only one doing such experiments! there are at least 2 of us 😀
