CE Project: CE Bot [PART TWO]

[bluegeek]

hi there....

I recently joined this group..the whole idea is freakingly good!!

I am not a big robot buff but have a bit of programming skill that may come in handy for you guys....

Can anyone brief on the whole project in a short type....

Waiting for your reply's!!

I have been out here, mainly due to my health. We will get back in speen in a day or two and dude above me ^ (sorry to lazy to check which page I had seen your new post welcome to CE Bot or CE Rcube.

I recomend you go through the main pages and the ones that interest you:: celab.tk

Hi ash, xheavenlyx !

Sorry folks

I cannot share those videos due to Copyright and confidential status; they have not matured for publication yet. They are my students' projects, under my guidance and mentored for specific purposes. There are some innovative changes in each of the Rovers and are not an exact replica of the original Rocker-bogie configuration and i dont like them to become prior-art just now.
It is different, if i make a new one independent of these and with a specific purpose, relevant to the CeRReconRover.

Sorry I've been out, guys! I was away with my work, but I'm back guys. I have this week to work on those designs before school starts. . . it starts on the 19th for me (Which is like next Tuesday) So. . . I'll be getting what I can done.

Ok, no problem, I understand you conviction. Since these are student projects you cannot share them . Generally, I get very confused with re-inventing the wheel, since its difficult to use whats patented, BUT I've heard its ok to use a patent if you add/improve the patent and credit the original patent holder. So, if you think the design you have used can be helpful then I hope you consider sharing it, because we will not use this commercially.

Anyway, we will have 2 suspension/chassis designs for CE Rcube. We can design them side by side or later in the project. One Rocker-b, and the other, large 6 wheeled drive.

Coming up, we will concentrate on Sensors, vendors and their input/output (IO) properties. Later, on physical placement with respect to processor/payload and power/physical connectors (wire) requirements.

I will design a presentation and post it here, we will follow an organized way. docel, if you have any suggestion regarding this please share it with us as you are an experienced designer.

Looks like we are not considering the friction part of the rocker-bogie design...in tougher terrains rocker bogie deisgns usually fails....similar to a car in sand...

Anyways if anyone has made any draft of the rocker bogie design can they share it please...i can take a look at it...

I'm going to start working on it. . . I've just been very busy lately! But please, bare with me as I try to get it done!

I have been away from the project for a few days. I am working on the presentation, plus have one more important project, so a little busy.

@Bluegeek, there are a few papers on Rocker bogie case studies online (Speacially, NASA's rovers which use rocker-bogie), and some have been posted on celab.tk (our project website) links are end of post. It would be helpful if you can read these and do some studies. I am reading one file, but I have to get a bloody print out to do it faster.

Actually NASA did have the traction problem, but they solved it with wider wheel and straight groves on the wheels for more grip.

Sorry, I've also been busy with stuff

Btw xhx, I'm planning to get my rotary set this weekend! Can't wait! not Dremel, of course Theres a cloned version of the Proskit rotary set. Should last me for the duration of my studies

Back to CE Bot.. hopefully next month I'll start constructing the Omni-directional antennas for the 802.11 module. I'll try getting hold of an SWR meter from the lab soon. I trust you guys with the decisions for locomotive module.. I dont think I have time to contribute to that bit at the moment

MUAHAHAHA! I just got my rotary drill last week!

.. its a clone of the Proskit one, called CT-800. Check here:
IPmart.com - Super Drill Set CT-800

Its cheap, but very hard to find in my city. Got some additional cutting disks as well.

Hows everyone else holding up?
