9/16/13 Update

There were a few less volunteers today, but tests are coming up.
I tried to get everyone onto the google drive; dont want to lose code/files like last time
The first report due Monday by 11PM

Mechanical:
We sketched some ideas for a "holder" to place everything on top
We decided to have the wheels attached directly to motor; this will require new wheels with a larger diameter.

Software:
A few worked with the MSP430 and some with Stellaris (a new microprocessor from Dr. Villareal)

9/9/13 Update

There were quite a few of us today, a lot of volunteers showed up. We reviewed where we were so all the volunteers were on the same page. Then we split into two groups; one working on software and the microprocessor, and the other group looking at the motor mount.

The mechanical group's goals:

-Method to attach the stepper motor; possibly have axle horizontal instead of vertical like in the kit
-Need some sort of holder to hold everything to get a prototype going. Would need to hold MSP430 launchpad, motors, motor drivers, wheels, sensors

Things we may need:

-bigger wheels
-more LED sensors

Software Group's Notes:

-Possible flow chart to help write maze solving code
-Experiment with uploading code to MSP430
-Get everyone to read and get familiar with the code

Other updates:

-For the next meeting, I will make a sign-in sheet, this way I can keep track of which volunteers stick around
-The president of HKN informed me that their budget is tight and that I need to write a proposal for funding
-I talked with someone last week about getting Inventor or Solid Works on the 225A computers

9/2/13 Update

--Microprocessor

Instead of using the MSP430, possibly change to an Arduino for more user-friendly coding. Then we can have a prototype sooner and start test runs.

--Motor Types/Options

DC Motor: has a counter on the axle but isn't very good
Stepper Motor: very accurate internal counter
Continuous Rotation Servo Motor: good torque and position reading

--Motor Shield

Needed for potential new motors. The example has extra stuff that we don't need (ex:http://www.sainsmart.com/starter-kit/mega-r3-starter-kit/sainsmart-mega2560-r3-l293d-motor-drive-shield-starter-kit-with-basic-arduino-projects.html)
Cost: Definitely less than $60

--3D Printing

Programs we may need: Solid Works, Inventor, or other AutoCAD versions
Need to know the printer's accuracy and what file type is acceptable

--Miscellaneous

First weekly report due 9/16 (if enrolled in the class)
Google drive called Micromouse - store code/files there for safe keeping
About 3 to 4 new volunteers might show up Monday

--HKN meeting notes

I attended the HKN officer meeting Tuesday night. They would like us to make a mini maze for demonstrations. Available funds still unknown.

8/26/13 Update

I emailed people and tried to see who was coming back this semester. The MSP430 and Seeley's completed code was returned. The sensor control code worked on last semester seems to be lost due to personal hardware failure. The maze solving code is lost, the person working on it never answered my emails.

A recruitment event was organized for the second week of school. Only two people showed up, but I got lots of emails from interested volunteers.

Semester Goals

Howdy! Tonight during our third semester meeting we are handing in our ideas about what we are to accomplish this semester and about what we learned these past few weeks that may help us in building our robot this semester. I look forward to seeing all class members this afternoon.

Weekly Meetings

Hey guys,

I would like to try and have a separate meeting time from the mouse class meeting time for at least those that cannot make the Monday 4-5 time, so please fill this out ASAP. Go to the link below and fill out the color corresponding with your name for every time slot that you are busy (for the whole semester, not just this week). It is 30 minute slots, so if the time says 5:30, that means 5:30-6. If you are only busy for part of the 30 minute block, do not color it in because we may have to have a meeting time that some people have to come late to.

If you have any questions, please let me know.

Late Night Labwork

Here are some videos of me with the new stepper motor drivers from TI driving the 35L unipolar stepper motors.

First tests

Modified tests

Let me know if you guys have any questions or comments. I will be working on this the first few days of the week if any of you want to come check it out. I understand that the video quality does not show up extremely well on the blog even though the original shot was pretty decent.

Thanks!

Brock
