today we had worked with lab view.
and experamented with joy stick control.

and jose did not want me to say this ;). but he mesed the program up so it would not stop or it would stop when we did not want it to:o.
(i hope he does'nt kill me for that)

and that was all i was here for so till next time. :)

Here's what we did:
Pit design (corral, trophy case), what to put in the pit. *Pit will be less than 10 ft tall.*
Materials needed for pit design and trophy case.
New flag design.
Shirt logo and design, colors.(Shirt will be black with silver logo/slightly different design)
Buttons and giveaways for pit.

Circuit Boards

;) We learned new software for creating circuits and mapping circuit boards: PCB123. The software allows you to order boards that you've designed. We also worked on the optical encoder board. Board size is 1.2"x1.0". Sensors are on the back side of the board. We also learned about Schmidt trigger inputs on logic parts. Schmidt triggers provide hysteresis which makes them ideal for converting analog or slowly changing levels to digital signals.

Today we had an overview off the new controller. We saw a transfer of data packets between it and the computer. We were able to plug in joysticks and see the servos working with our hoysticks. We performed the "bench test" on the new controller we hooked up tyhe console with the cRIO, we then took a look at the base code of the robot that came on the system, which in the launguage of c++.
We discussed watch dog and basic c++ termilogy and structure and modified the program on the robot to sample the X and Y coordinate values of our joysticks.
We hooked up a wii-remote via bluetooth and saw workings of in with a program we downloaded.

Mechanical Team Wheel Discussions 
Tuesday, November 25, 2008, 07:28 PM - Mechanical
Posted by Kevin K (student)
Today we discussed different wheel options.

In General:
-Wide tires tend to be difficult to turn
-Narrow tires are easier to turn due to less surface on the ground
-We also want to buy, rather than build, wheels.
-We talked about different readily available wheels, such as tricycle wheels.
- We looked at wheels on the web.
-Omni wheels are interesting...

We also talked about feedback. We need to consider how we mount potentiometers and encoders for computer feedback.

We went off on a few ways to control the robot. Tested touch screen design. Tried the infared wii remote style. Bluetooth was a problem. May fix later. Talked about simple programming.
