This is the first part at my initial prototype of my final project for Fab Academy. It’s a continuation of my Solve for X moonshot robot idea.
Fab Academy is a global distributed class for learning how to make (almost) anything at Fab Labs around the world. I’m participating remotely, my remote guru is Shawn Wallace from AS220 in Providence, Rhode Island. He actually gave RoboBrrd a Maker Faire Editor’s Choice ribbon in the past! Cool! I will be visiting EchoFab in Montreal, Quebec to do some of the lab work too.
Check out my Fab Academy page for this week- Computer Aided Design. So far it is quite a neat experience even as a remote student. I’m psyched for FA all the time, what a cool opportunity! It will be what I make of it, so keeping my eyes open to try new things and challenge myself.
As I learn more each week at Fab Academy, I’ll be able to improve on the final project design for next time. The reason why I’m starting now is to hopefully have a simple demo done for Maker Faire Bay Area or even RoboGames.
Alright, finally, let’s bring on the images and captions from the prototyping process!
Working on creating a base for connecting multiple robots together. There are a few requirements that I had in mind- mainly it has to be able to fold up, and has to be light weight.
Here’s a cross section of the base. It uses internal 3d printed hinges.
The hinge design is parametric. We actually got the dimensions right for 3dp on the first try:
Added littleBits to the ends as the prototype module connectors. Here’s what it looks like folded up:
Assembling it! (Cool sounds in this Vine!)
Here’s what it looks like all assembled with links holding it in place:
Connecting it in different ways:
This was a neat surprise- the modules do not have to be flat along a surface. The connectors are on a piece that swivels, so here you can see they are at 90 degrees to each other:
What if one of the links was bent? That might be cool. I tried to print this:
Had a filament jam:
Finally it worked (had to print with supports, lame)- but conceptually I messed up on the part. Derp derp.
That’s all for now. Next step I’m working on is the first robot to be placed on this base, followed by creating a spec for the controller board and interface board. (So that I can order the components early and they will get here maybe on time)
