Working on version 4

A project log for 3D Printable Robot Arm

A printable robot arm, a little bigger than the usual hobby servo once.

Here is my new Video of the robot arm project:

I also started uploading the cad files on github:

Still a mess I try to clean it up in the next weeks.

why is downloading stuff so difficult on Github? I can't even figure out how to do it, it just opens the file as if it were text

  Are you sure? yes | no

Ended up clicking the stp file, it open in the browser as a txt file, right click browser and "save as" - man they make it so easy! alright now I'm digging in, can't wait to see the insides of this thing!

The twisted belt on the wrist is really cool, all of the little torque increasing belt transmissions you wove in and out are really clever. Nice job!

The twisted belt works surprisingly good, I didn't expected it working with so less additional resistance. 

  Are you sure? yes | no

Can you post a step of the whole assembly. Even it it is not 100% complete it would be nice to be able to look at it.
