I made a guest appearance to the ECE186a class at school today. Its a "Senior Design" class. Every Senior has to complete a project before they graduate. We got the great idea to contract out the Inductive charging and the GPS networking to them.
There are 2 classes. I will be speaking at the next one on Thursday. Today there was only 1 person who was interested, Ben Hawkins. He said he might want to do the GPS stuff but no one else wanted to, and he can't do it alone so he might get screwed. Anyhow, next update will be after this Thursday. I'll let you know if anyone else expresses interest in contracting some of this work.

I have a purchase order for (3) x BS2p40
I talked to Diane this morning about getting the PO submitting. She gave me paperwork that Dr. Nunna has to sign to signify he is responsible for authorizing our purchases. I found him in his office, but after a short disccusion we decided it would be best to come back. The reason is I'll have to come back anyways to have him sign yet another PO for our transducers we are purchasing. Dr Nunna was, of course, short on time so I'll just get the signature next week.
Brian, lets get a screen shot of the total cost of the sonar system. Lets get this rolling. I'd love to see what kind of sonar/bs2 action we can obtain.
Still no word on motors. I'll bug Ron about it sometime.

Purchase order for the Basic Stamps has been prepared. Does anyone have any suggestions on electric motors?
Here's the programming manual
for the Basic Stamp. It includes the syntax for all of the Basic Stamp series chips. We're getting the BS2 p40 (32 i/o's). Its teh only one that supports the I²C protocol.
guys, I'm not feeling very comfortable with this 2 wheeled plan we changed to. It's just to easy. I can see going with this in the short term for prototyping but I think this is sorta pathetic for our ultimate plan.

Good Bulldog Bot Meeting.Today's Meeting Roster:
Brian Ankeny (back from the dead)Things we got done:
-Discarded the CAN protocol in favor of the I²C protocol. (CAN seems like overkill)
-Changed from a 4 wheel to a 2 wheel design for simplicity.
-Voted to use BASIC Stamp microprocessors. Specifically, the BS2p40
Also, we have a new Mechanical Engineer on the team. Leslie has a busy schedule ahead of her for next semester and has bowed out. Lets welcome Paul Xiong
. Paul couldn't make the meeting because he had to work. He didn't find out about the meeting until last minute anyways. We look forward to his participation in this project.
Ok, back to business. Money. We have a bit of cash to spend and it seems that we will have a bit of delay between submitting Purchase Orders and receiving goods so we went ahead and got some things lined up to order.Things to buy:
3 x BS2p40 chips (only the BS2p supports I²C).
? x Sonar transducers
2 x Electric DC/Stepper motors capable of moving 30+lbs. 12V preferred (because of batteries)
2 x 12V Lead Acid batteries. Heavy and big but easy to work with
2 x Air filled tires ~10" diameterTO DO LIST: Tom:
-make a Purchase Order (PO) for 3 BS2p40's
-make a PO for 2 electric motors
-make a PO for 2 batteries
-talk to Paul about stuff
-research new I²C protocol for BS2Brian:
-make PO for transducers
-bring ooPIC to school for Sean to play with sonar
-research new I²C protocol for BS2Sean:
-get ooPIC from Brian and fiddle with sonar
-research new I²C protocol for BS2 and ooPIC

When: Wednesday, August 18th, 2004.
Where: EE 226 (IEEE lab/storage room)
Why: We have money to spend.
Thats right, we have money to spend.
I checked into the $2000 grant we requested from ASI and it turns out that we have been approved for $1000. We need to make an invoice and submit it to Diane and she will place an order for us.
Also, it turns out that we have money through an abandoned ME project. We need a meeting to start talking about actual plans and go from there. See you Wednesday!
PS. Anyone interested in the project is welcome to attend the meeting.

is making me do it.
Be there or be elsewhere.

Here's an email I recieved from Brian Ankeny.
Hey. I got your email and wanted to reply. I apologize that I have not been "in the loop". I have been checking the live journal for updates but there were none since the 29th of June. I just now discovered all the emails in my inbox. I haven't been checking my email account because I have been so busy, I assumed that any info would be posted on the live journal.
I do want to stay involved in the project and I will monitor my emails more closely, As for future meetings, if it is short notice please call me with the info.
My home number is if I am not home leave a message and i will contact you.
So where are we on this? What are the new ideas for the bot? Where do we stand on funding? Let me know what is going on.. Sorry again for going "MIA".
I explained to Brian that we're using this community instead. Easier for members to post on. Well, I ended up having to flake on Sean last weekend and am eager to make it up.. problem is my mom is in town so I'll be MIA for about a weel hanging with her. How about a meeting on 8/8/04 or 8/9/04 (sat/sun)? We'd love to fill in Brian on everything he's missed (which isn't really that much).
Brian, do you remember who it was that was in change of that AS money we requested? I don't think we ever heard back about it. Would you be able to check into it?

The meeting has been canceled, I have to move into a new home and can not make it.

Meeting this Saturday to discuss brains
Meeting this weekend. Leslie, its not necessary for you to come, we're just going to be talking about electronics stuff.
Sean and I have mentioned getting together to discuss the brains of the bot, from a conceptual point of view. We've been thinking about getting on paper some ideas as to how this thing will be reacting to its environment and how it functions.
We're thinking flowcharts here..
If anyone is interested in coming to the meeting other then Sean and I, *cough* Brian and Mark *cough*, or anyone else who is interested, then feel free to come on by room EE226 (the IEEE Lab) this Saturday at 11am.
See you there!

Our meeting was canceled because Leslie canceled, and she was the only one we were expecting. Everyone else has deserted us. (Except Dr. Nunna, who's laying out on a beach somewhere that is 8 or more timezones away).
Sean and I are going to be getting together to make a flowchart consisting of how our bot will react to things. I'll be assembling an invoice which will consist of:
~$270 ($90x3) BASIC Stamp
~$ 90 ($30x3) CAN microcontroller
~$100 misc parts. (switch, plugs, batteries, regulators, adaptors)
Dr. Nunna, how would you like this list presented?

Uhm... ok, maybe the 'legs' thing is a bad idea.
Cross posted on microcontroller
For this project I'm working on, I'm ultimatley going to be connecting whatever processor up to a CAN controller chip for use in a CAN (Controller Area Network) bus. Is anyone familiar with the CAN bus? We're being a bit over-ambitious with several processors multitasking independatnly and broadcasting/sharing data via the CAN bus.
I've been reading up on the CAN protocol and there are several different chips available that are listed, namely the Mot 68HC05x4. It looks like that chip is actually called the 68HC705 family, but the datasheets don't really talk abotu CAN whatsoever..
Is there anyone out there familiar with CAN who can save me?

This looks promising for a CPU.http://www.k-team.com/boards/korebot/index.html
Its LINUX only, has a TON of memory (64meg RAM and 32meg Flash) and offers these as accessories.
KoreMotor drive up 4 DC motors.
KoreConnect (2 x RS232, 1 x USB Client).
What do you think Sean?
I propose we modify our design to acyually look and operate like a real BULLDOG. By this I mean, have legs, with joins. I know I know, this would be a pain to implement.... Its a good thing I'll be in charge of it then :)
Here are some preliminary pics i drew.
This one shows the numbers I gave the joint servos.
A little better pic of what I'm picturing..
I am planning on pickign up a PIC and playing with this myself..
What do you guys think?

email to team members
An email to all bulldog bot project team members.
Bulldog Bot update:
We have accomplished little.
We need a meeting.

Probably you best bet would be to use a wheelchair propulsion system. There are several different type out there and the mechanics and gears are already worked out. I have seen some of these available in surplus catalogs. Do a web search for them. For you final full size version, you will definitely want to go with an electric golf cart type system, also readily available. . .
