Just finished a week of Fab Academy where I learned a lot of info and tried new things! There were some interesting fails and challenges along the way. The first half was creating a flexure mechanism, and the second half was learning a little about function representations and importing points into Antimony.
Here are the highlights, if you want to read all of the details please see my Fab Academy page!
To continue working on the robot project, I created the first test of a flexure mechanism. It is based on Flex-16.
3D printed in PLA. Uses a micro servo and a paper clip linkage:
Here you can see the flexibility of it (though this was in ABS):
There is too much movement in the z axis to make it useful in the robot idea (see vine video above). Have an idea on how to make the next one. Flexure mechanisms are pretty cool, I’m excited to try to build a robot with them.
For the scanning aspect, I wanted to be able to display slices of a 3d model in Antimony and maybe blend two models together.
Here was a first attempt that failed:
Went to the idea of just displaying shapes where the points are. It sort of resembles the Stanford Bunny:
Created a node for Antimony that reads in the points. 3 of them in action to display the pieces of the Fab Lab logo:
More info about these is on my Fab Academy page.
Lots of electronics coming up next. In the lecture, I can’t believe people used to use tape to make circuit boards by hand! The fab modules has an EDA tool where you can make the board by typing commands. It will be interesting to try it out compared to my previous gEDA experiments.
