UPDATED 10/17/2009 at 10:37pm  - Revised code to remove use of Mini-Blocks 

This is our Cougar Calibrate program.  It is set up to use the light sensor on port 1.

  1. Start the program.
  2. Move your robot around until the light sensor is reading the lowest value you can easily find on the field (darkest spot).
  3. Press the left button.
  4. Suddenly it will be reading 0 for that dark value.
  5. Move the robot around until the light sensor is reading the brightest value you can find.
  6. Press the right button.
  7. Suddenly it will be reading about 100 for that light value.
  8. Move the robot around checking to see that the light values are ranging from 0 to 100.
  9. Stop the program.
  10. Do not run it again unless you want to recalibrate again.  The first step of the program resets the light sensor calibration.

Several teams have asked us about our use of magnets.  We used magnets extensively in the Power Puzzle and a fair bit in Climate Connections.  We will probably use them again this year.  Here are the parts we use complete with links to  them on Bricklink.

The Magnets themselves are LEGO Part # 73092 -> http://www.bricklink.com/search.asp?q=73092

The magnet holder we use most often is Part # 2607 -> http://www.bricklink.com/search.asp?q=2607 

Some other magnet holders we have and have occasionally used are Part # 2609 -> http://www.bricklink.com/search.asp?q=2609

and Part # 30159 -> http://www.bricklink.com/search.asp?q=30159

 
Bluetooth USB Adapters PDF Print E-mail

The Lego Mindstorms support page lists several Bluetooth devices that are supposed to be compatible, however, that was with Windows XP. Some of the devices have bad reviews when it comes to installing and working with Vista. The Belkin F8T013 does seem to have good reviews with Vista. The Abe UB22S is the one that Lego sells.  Local sources don't stock much and the ones they "Ship to Store" (i.e. WalMart sells the Cables-To-Go device) have reports that they are not compatible with Vista. Buyers would be well advised to do some research on the web before buying anything.

Here is the link to the Lego Bluetooth compatible devices: http://mindstorms.lego.com/overview/Bluetooth.aspx.

I will try to get some screen shots of the steps to set up Bluetooth in the MindStorms program. If anyone has anything already - please send it for me to add.

Do the Cougars use NXT-G or Robolab?

We're using NXT-G 2.1 with the addition of some standard sub-routines and the legacy integer math blocks and the legacy mini-blocks.

    These teams are invited to a welcome reception at FIRST HQ in Manchester, New Hampshire, USA, the evening of Thursday, July 27th. Friday, July 28th, invited teams will be splitting their time between a visit to Dean Kamen’s company, DEKA, across the street from FIRST HQ, and time on the field at the event venue, getting their robots calibrated and ready for the big competition the next day. They may even get in some practice with their alliance partners. 

    We know everyone will be excited about Saturday morning, July 29th, the official start to the competition. The competition will be followed by dinner at Dean’s home in Bedford, NH, right next door to Manchester, NH.

    The Competition

    The competition portion of the event will take place at the SNHU Arena in Manchester, which will be a great venue for this event. At this time, the competition is scheduled to take place between 9AM and 12:45PM Eastern. Both FIRST Tech Challenge and FIRST Robotics Competition matches will be run during this period. Teams will compete in up to 5 matches. Everyone is welcome to attend this portion of the Festival in person, and join the party! The event is free and open to the public, just like all other FIRST competitions. We will have plenty of seating available. Driving directions and parking options for the venue can be found here. Please note that there will be metal detectors at security. Please don’t bring your backpacks. Outside food and beverages are not permitted in the venue!


    For those who can’t make it in person, the event will be webcast. We’ll have more details on viewing options at a later time, and we are working to make the at-home viewing experience well worth your time.
