CHIBOTS MEETING: DECEMBER 17, 2000
ChiBots, Chicago Area Robotics Group, met at the Schaumburg Public Library at 1:00 PM.
It was a good crowd! Fifteen people attended. Everyone didn't even get a chance to get around to talk to everybody else.

Mike encouraged everyone to attend the Critter Crunch contest. He distributed rules and Capricon 2001 Tellurian Exposition flyers.
Mike also showed his robot that is being built on a tank base. The solderless breadboard is for prototyping, but will be replaced with something more permanent before battle.
Jim showed off his HC11-based mini-Sumo robot.
More importantly, Jim talked about the Trinity College Fire Fighting contest. Jim would like to host a regional qualification contest in Chicago. Jim's fire-fighting robot demonstrated sound activation, sonar ranging, flame tracking, and flame extinguishing. It's a really cool robot!

Tom impressed everyone with a dual Maxon motor base of two salvaged treads. Very quiet operation and good speed.
Tom showed some interesting and low priced batteries he discovered. Tom also brought a big bag of nylon spacers to share with everyone.
John brought a tiny CMOS digital camera module, a pair of radio modem development boards, and a powerful PIC clone chip board.
He discussed his plans for teams of vision-enabled robots that can play capture-the-flag. The base body is made from standard copper PCB board. Not only is it a strong, lightweight material, but also the copper acts as a noise-limiting plain.

I brought Sweet, the line-following robot. The red table is a bit difficult to discern from the blue masking tape line when a monochrome red LED is used to determine contrast. Still, Sweet performed well.
At the end, Bugdozer sparred with Jim's mini-Sumo.
What a great turn out! Please come to a future meeting -- all are welcome.

2. CompetitionsAfter some discussion, it was decided that we would hold our first competition some time in April or May of 2000. The third Sunday in May was suggested. The competitions to be held will be Line Following and Sumo. The Sumo weight classes will be 500 g and 3 kg. Potential venues were discussed briefly. Brian Schwartz suggested that his school would be interested in hosting the event. Other suggestions were the Museum of Science and Industry and the Sci Tech Interactive Science Museum in Aurora, as well as local universities.
Previous CIRC President James Munro suggested a Firefighting competition. This event will be planned for future competitions. Time and resource commitments need to be investigated. Registration in advance should be required to ensure that the event is properly scaled to the number of competitors. This will be discussed further in January, 2001.
Mike Bakula discussed the Critter Crunch competition at the Capricon Tellurian Exposition. Mike also passed out Critter Crunch rules and Tellurian Exposition flyers. The time and location for the Tellurian Exposition are:
February 8 through 11, 2001The Critter Crunch competition, which takes place on Sunday, February 11, is a cross between Sumo and BattleBots. The contest takes place on a table 8 feet by 8 feet wide. Two weight classes are allowed: 20 pounds and 2 pounds. Size is limited to 12 inches by 12 inches. Cost to enter the convention is $30.00 for one day, or $60.00 for the entire weekend. More information is available from Mike Bakula, firstname.lastname@example.org.
3. DemonstrationsSeveral small robots were shown and demonstrated. James Munro showed three robots: a mini-Sumo robot, a Firefighting robot, and a light-sensing robot. Tom Gralewicz showed a tank tread base made from two tape drive transport mechanisms. After borrowing a battery pack he was able to show the base moving across the table. Mike Bakula showed a robot base made from a scale model tank. David Cook showed his line-following robot made from a racecar shaped m&m's box. He also showed his Champion Mini-Sumo robot, Bugdozer. John Orlando showed a base made from a printed circuit board and two servos with wheels attached, and a pair of FM Transceiver proto boards. (Pictures of the robots are available above.)
4. Swap meet and door prizesTom Gralewicz brought in a large bag of nylon spacers and some 2 A, 40 V op amps to use for motor controllers. David Cook brought LED packs (10 rectangular LEDs side by side in a DIP package) and chip sockets.
