I suppose the previous message on this account (posted 6/29/04) didn't really mention how we started treating this account. We are no longer posting on this account because if someone wants to originate a post, they must log into a common account (bulldogbot). The 'community' account that I spawned off from here (bulldogbot_csuf) supports postings from anyone who has an LJ account. On either account, anyone can respond (comment) whether they have an LJ account or not. If you are commenting without an account, they would post as "anonymous". Please leave yoru name if you do this.

Basically, the community is better so we're using that now. There shouldn't be any more posts on here that pertain to the bulldog bot project at Fresno State. All posts will be made on its community, who's link is below.

nothing going on
Well, we haven't had a meeting in a while and all that I can see that has been done is Sean and I looked up some info on CAN. Other then that, progress has halted.

semios says we should add this feature to the bulldog bot.

And on the 8th day, there were pics.


At the last meeting we mentioned a smaller version of a bot, instead of a golf cart. We ended up thinking of something 'power wheels' sized.

*Bing!!*

We had an idea. Its time for a Toys R' Us run.

I just couldn't behave myself. I insisted on test driving them.. you know, for prototyping purposes... :)



This tractor was awesome! It had a scooper and everything!


The sign said I was ok


---------========= Back to Business ========---------

After looking under the hoods..


We found there were 12V options that claimed 2.5mph/5mph speeds



And 6V options (cheaper) that did not mention a speed.


After seeing (and playing) with everything we thought we needed, I noticed this Radio Flyer. The steering method, even though basic, seemed like an honorable mention as an option for our Bot.

I'm thinking we need a meeting soon. Sean and I have been looking into the CAN system and it looks like we need to get our hands on a CAN chip. I like the idea of it only really needing 4 wires. Makes it handy for using RJ11 for connectivity between modules.

When would a meeting be good for you guys?

We need to get into gear here. The summer is whizzing by quickly.


Leslie, any ideas on designs? Sketches? Size?

I'm guessing that if we're doing something smaller, you could fabricate it from scratch. That way we/you have full power over what it looks like and how it steers. If you have any time, could you sketch up something and we'll get it posted on here?

Does anyone know of a free ftp we could use to host pics?

Welcome Back Brian!
Brian, welcome back!

TO DO LIST for Brian:
pretty much do the same thing Mark and Tom are doing.

Research this CAN bus and find a CPU to handle most of our code which will be on this bus.

At our next meeting (which is currently un-planned), we should really start splitting up into specific tasks (ex: GPS, cpu, AI, sensors, locomotion, CAN, ect ect).


-Tom
10:33 am
Well it looks like we're not looking for the CAM Bus but rather the CAN Bus.

Controller Area Network (CAN)

This doesn't seem quite like what i was expecting for the CAM bus system but this is something I found.

Is this the CAM bus you were speaking of Mark?

Meeting Update
Meeting update for 6/6/4 JamaJuice meeting

Roster:
Dr. Nunna
Tom Pittenger
Sean Kraus
Leslie Perryman


Mark, did you get my voice-mail?
Something tells me Brian sold everything and bought a one way ticket to a small island in the Bahamas.


It looks like (under Dr. Nunna advice) we should change our tactic of 'golf cart' sized cart to a smaller, more practical 'power wheels' (kids toy) sized vehicle. (pics soon)

This was due to the unrealistic vision we had of implementing an autonomous vehicle capable of transporting a human(s) to anywhere on campus they wished (or to certain 'bus stops'). Due to obvious legal issues of a robot whizzing around campus potentially running people over, full steam ahead, we decided to make a scaled down prototype.

We will most likely never use an actual golf cart, at least not anytime soon, because what we are after is 'proof of concept'. This means once we have the technology and research done, it doesn't matter what we implement it on. Why burden ourselves with having to store and manage a huge golf cart when we could deal with something much smaller and get the same job done.

Also, we should be hearing about some money soon. In possibly 2-3 weeks we'll know where we'll be standing on that issue for the Summer and Fall.

There is some good news from Dr. Walter Loscutoff. He says he has a few bucks he can re-direct from an old abandoned project to The Bulldog Bot. More on this at the meeting on Sunday.

Dr. Nunna,

Are you available for 20 minutes sometime during this week after 1:30pm?

At the last meeting we were walking around the IT/EW buildings and we have a few candidates for storage areas for the Bulldog Bot. It would be nice if I could show them to you prior to our next meeting. That way you'll see what we're talking about.

Hello everyone. This is the LJ for THE BULLDOG BOT project at CSU, Fresno.

Our plan is to have our team use this as a forum for communications. This way everything will be logged and we won't miss anything. Communication is #1. Just to let u all know, we don't have the project concept set in stone yet. Its goals are currently up in the air. Soon we will be having meetings that will define what our project will be.

The idea of this came from the DARPA challenge that happened a few months ago. The government offered a million dollars to anyone who could provide a vehicle that could travel from Barstow to Las Vegas autonomously. This is a huge task. Infact, the farthest anyone got was around 5 miles. What we are attempting is a small version of this.

What we think we want:

A vehicle/robot that can...
1)deliver people from the parking lot to their classroom. (vice versa)
2)navigate throughout the Fresno State campus (or most of it).
3)transport 1-4 people.
4)know where itself is and can go anywhere from anywhere.
5)avoid people
6)stay on the sidewalk (road travel is probably a bad idea)
7)park itself when its batteries are low or when its not in use
