Description

2013 Southeast con robot. This robot will be full open source, but until Saturday morning 4/6/13 the files will not be open to public, ;)

So bad news, we lost. Yup, in the process of losing we developed a new term for amature mistakes. "Revpol" this is defined as apply voltage backwards, or reverse polarization.

Anyway, we will be uploading all source code soon along with a BOM. In the meantime until the team is ready to upload everything I will answer questions regarding the build in the comments as to get people going.

Your lifting power depends upon how long arm is. Lifting 1.45 kilo is a lot.

Hi MaverikIdeas. You guys did a great job on this robot. I love the look!

I am curious how you connected the turret up to the plexiglass top. Did you use any bearings between the two layers or just let them slide against each other?

At the end, what kind of weight is the arm capable of lifting? I am currently in the "studying stage" of my robot arm build and I am aiming for ~3lbs, if possible. I am also debating on using aluminum parts or print my parts for it, did you feel comfortable with the sturdiness of the printed arm?

Thank you and the team for sharing!

Note that i'm seeing 2 different robots here in the first 2 pictures. One that's rectangular and one that's bend for the plastic of the robot arm attached to the rotating platform. I personally like the rectangular thing more, missing the STL's though from it. Would prefer those in OpenSCAD most. Have those still somewhere?

Note for robot vision having a camera that's nearby 1 fps, why would that be a bad idea from your viewpoint? I'm intending to run self built robot vision software at say a quadcore ARM or something. Those very pricey to buy in. The SoC's are $30 a piece if i buy a 100 at a time at 1.0Ghz, but a SoC in itself is not usable. The Odroid thing is $89 and quadcore 1.7Ghz or so. That's a tad expensive. The electronics is massively overexpensive for the robots.

Instructions

So we posted some singled out items for you. But for the most part the entire sketchup file is available and parts can be picked and exported in a singular fashion.

Tank tracks:
These were printed, but I had to dremel out a nice amount of material to create a bevel for the sprocket gear to enter and exit the linkage without bindage.
I used a drill bit to clear the holes keeping all holes in the tracks consistent at around 3 mm-3.1 mm whatever drill bit you have. I then used cut pieces of polycarbonate 3mm longer the the tracks are wide. Insert and use a lighter to get the end hot and then use the lighter to push the rod in the tracks "mushing" the soft plastic and creating a riveting effect. The repeat on the other side. Leave one link where this is not done on the outer side; this is your master link. ABS should work just fine.

Thanks for the link to the servo motor board. At $20 it's half the price of the $40 board that robotshop has, so that's very cool and 6 servo's might be enough for a first ayatollahkillerline robot here :)

Note i'm still looking for a simpler way to design tracks. The huge work you have for each link is way too much IMHO.

Looking at printing the entire track at once using flexible pla or something similar!

Such tracks are stronger as well than selfprinted links.

Yeah i wanna build something like this. Maybe tad more sophisticated gripper. Of course pattern recognition and AI and navigation are my core expertise. I'm a bit amazed you scored so few downloads and views. Thingiverse is a bit weird there i noticed that more. Some total junk designs (in different fields) get massive hits and the funny stuff sometimes hardly.

Heh is it possible to get your CAD files in SCAD format (openscad), the open source software is very incapable of converting from other formats to itself. The STL's i can't do much with except when i want to build the 100% exact thing.

The SKP files i have no software that can convert it to OpenSCAD format.
Email me otherwise at diep @ xs4all dot nl

From diepchess

wow great robot!
-----> thank you!

How did you construct the tracks? seems like links that have pins.
Did you buy the links or print them yourself?
-----> We used a 3D printer, Yes, they do have pins, or what I like to call rods.
-----> I used polycarbonate filament. You can see further in the instructions.

Do you combine DC motors with servo's, using 2 controllers or?
Which camera are you using?
-----> Well, technically servos are DC motors, but yes we used servos. App. 6.
-----> We also used steppers, app. 3. The steppers were controlled by a RAMPS
-----> The servos were controlled by http://www.pololu.com/catalog/...
-----> Camera - Microsoft LifeCam Studio 1080p HD webcam; Q2F-00013

I see one at robotshop of $9.95 i can use yet takes long to get the machine vision software the pictures as is low FPS (far under 1.0).

-----> We Will be uploading all of our source code very soon!

I am looking forward to seeing this along with some competition pics. Perfectly reasonable to hold files until after the event.

TY, coming soon

Thats nice of you, thank you. Please don't click the link if you can't wait until the posted time

Not even a pic or an artist concept or a 140 char description?

Kind of defeats the purpose to post your plans to all you hard work before you actually complete
