    Weekly Report

    Mechanical
           In the last few days of the build season, we assembled our lift and attached our secret weapon onto it. Our chains were then replaced with foreign-made type 25 chains. Next, we did a number of tests and made necessary adjustments with the machine. During practice, we switched two of our wheels with omni wheels in order to test for maximum efficiency. In this test we observed that the machine performs best with the omni wheels in the front.  In all, we had a wonderful build season and now look forward to the competition. Good luck everyone!!!

    Electrical
           We thought crunch time would never come but now it has already ended.  Crunch time was a very busy time for all the sub-teams as we put together all the stuff we were working on.  The mechanical team finished their part and with their finish product, we were able to attach the final electrical components on to the robot. Our speed controllers, pneumatics, wires, circuit panels, and such were finally placed onto our robot and were finally able to do programming for our lift and for the autonomous mode. 
           For our elevator lift, we placed limit switches at the top and at the bottom of the lift to prevent the elevator from smashing into itself.  Moreover, we created set points for the lift.  That way, we can use toggle switches to move the lift up accordingly to the set points we created for the overpass and such. 
           As for hybrid, we are using a potentiometer to indicate which autonomous program to run and we are also using the toggle switches to indicate the position of the robot and the IR sensor to indicate the position of the robot relative to the ball.  In this way, we can tell the robot to move toward the ball during the hybrid mode.

    Media
           Crunchtime was interesting for us as we recorded the last 3 days with the cameras and video cams in our build season. Our pictures accurately recorded the hustle and bustle of each team as they tried to finish on time.
           The media team has uploaded some new videos on our Google video server for the people out there supporting us to enjoy. We have modified our website a liitle bit as well. We just added the Crunchtime webpage, but remember, this webpage is only dedicated to 3 really important days, so there may not be as many pics as you would like. But, enjoy!

    Inventor
           During the last few days of the build season the Inventor team moved over with the mechanical team and helped out with the robot assembly.  This was a good way to let the new members who are on the Inventor team more about what happens when assembling the robot.
           During the times at the mechanical side members of the Inventor team took inventory of all the parts and accessories that were bought throughout the season to find out how much we spent this year.  For the new members, they had a chance to learn about the parts and components that they were not familiar with.  So now we were able name and understand the names and functions of all the parts.
