I know there are people looking at some exotic stickers for the 'bot, but how abuot thinking about the basics for a bit? There are are some requirements we must adhere to: First, we need to have the team number on all sides of the 'bot. Second, we need to display sponsor logos. It is a REQUIREMENT!Posted by Dean Klein (Mentor)
Last year we put logos on the bumpers, but with green bumpers this year that may not work so well.
Thanks.
Dean

We made significant progress tonight with lowering the loader brush.Posted by Scott S (mentor)
We lowered the brush wheel down 1/2" and moved it in toward the elevator assembly an 1". The brush relocation also required the drive motor mount to be relocated. Looking forward to testing tomorrow!

Jose made progress on a new camera mount (in front of the drum) and on the turret wiring. He will continue to work this tonight.Posted by Dean Klein (Mentor)
Thanks for the bumper measurements. We will work on those tomorrow and Wednesday evening.
Looks like Friday is a school holiday. My schedule looks decent and I can probably work 1/2 day. Other mentors?
Note to Randy: I set the monitor out for Kevin to bring. It takes a 12V input at 3A. That's only 36Watts and is well in the range of the proposed batteries.
See you Wednesday!
Dean

Today we plan to:Posted by Skyler H (student)
1- Move the camera so that it can't be damaged and so that it will fit the height requirements/ game rules/ height
2- Refine the groundhog so that it can feed the balls better
3- Put the chains on the wheels
4- Get sensors wired
5- Refine the electrical stuff
6- Add game light
7- Review the rules of the robot
8- Practice with the robot on the practice field
9- Chassis refinemet/dimensions

Another observation from Sat. As we reduced the range our RPM fell on the "spinny thing of dooooom!" and would actually jam up. This is another place where we need to look to adding the PID block to keep the RPM constant. We may need to play with it as the PID block will need to feed more power as we launch balls to keep the rpm up and not jam. Another task for us to get working tonight is the encoder feedback from the "spinny thing of dooooom!".

Well we ran the controls in manual mode with manual speed control. Suggestions were made about being able to revers the elevator and the ground hog. Software will need to look at some options to do this with the controls on hand.
James worked with Dean to adapt a PS2 controller to work with the drivers station. This still need to be tested to make sure all the buttons function. The axis controls need to be fine tuned as well.
Final dashboard designs need to be done so we can have mechanical and electrical look at constructing it for us as software team fine tunes the robot.
We also have an issue with the new camera code bogging down the control system. We need to do some debugging tonight (Monday) and see what may be causing it.
Lots of software work to do still!

Hello all!Posted by Dean Klein (Mentor)
Tremendous effort from all teams culminated in a running robot last night. I think it was safe to say that all parties were pretty impressed by the initial capabilities and everyone is looking forward to the fine tuning we'll do this week as we wrap up the robot build.
This is not to say we're done with the build! Still need to machine more sprokets and clean up wiring. I will bring my label maker tomorrow night and it would be good for the electrical team to get labels on every wire running into the electronics package.
Several of us worked on a method of cleaning up the wiring from the turret. Randy had a good suggestion that we need to mock up. If we can make it work it is possible it will make things a little simpler. I will pick up a few parts to try. One of the possible implications would be that the camera might have to be moved slightly to one side. Stand by.
Keep on running! Only a week left!
Dean

Tonight, Nick, Skyler, and Cassandra designed and cut out another foam groundhog. It was dimensioned at 5 inches by 21 inches. We cut it out so that it was (basically) circular. But, before we decide what material we want our final groundhog to be made of, we are going to fine tune the brush/bristle groundhog; then we will test it so that we can figure out which one will give us the best results.

On sataurday we plan to have a small group of about three people complete ALL the balls. In other words sew them and rivet them. Posted by Skyler H (student)
The groundhog team will be createing groundhog possibilties and will hopefully create the final design for the hopper.
The turret team is planning to test the turret shooting at a moveing target sooner or later.
The chassis team claims to be done so they will be helping all the other teams.
Good luck and let's get 'er done!
