180M Mark II
John Patrick brought 180M Mk. II, a Critter Crunch contestant robot. It's a remote-controlled robot which runs on 4 NiCd batteries (4.8 volts).

It has three servo motors, one of which lifts the front scoop. The radio controller (not pictured) is attached with Velcro, so that he can use the same component in other robots. Although some nuts and machine screws are used to attach the motors, most of the body is connected with aluminum pop rivets. The rivets don't loosen like nuts can, yet are just as unlikely to break under the battle conditions this robot faces at 2 lbs.

Door Prize
John gave away a stepper motor that he salvaged from a printer. The lucky recipient, Dave, kept asking about specs. "12 volts or 24? How about wiring diagrams?" Perhaps this agenda item should be renamed to "white elephant".

After the meeting, John Patrick invited us outside to pull Endotherm out of his car trunk. Endotherm competed in BattleBots. John was rightfully proud of the deep groves, scar, bent brackets, and overall battle damage.

John Patrick also showed us a framed pair of wheels (one-half total) for his next model of competition robot.

Meeting Minutes
by David Wooden

First, I apologize for the lack of detail; I didn't know I would be doing this when the meeting started.

Minutes from the third ChiBots Meeting, September 17, 2000:

In attendance were Lee ( I didn't get the last name; Please let me know, Lee), John Patrick, David Cook and David Wooden.

Nobody had brought a copy of the agenda, so we followed through by memory. The agenda followed was: Show and Tell, Constitution discussion, Nomination of officers, Purpose of the group and Door prize.

Show and Tell:
John Patrick brought in the base from his Critter Crunch robot, 180M, to show everyone. John also brought pictures from the BattleBots events he has attended. We discussed the events for some time. John revealed some of his sources for components:
C & H Sales, (800) 325-9465
W. M. Berg, (800) 232-BERG
Surplus Center (800) 488-3407

Points were raised about references to IEEE Student Services being removed, as they were left over from a previous document. The removal of officers was also raised, but this point requires some further thought, as this is a sensitive issue.

Nomination of Officers:
John Patrick was nominated for President.
Jim Fiocca was nominated for Vice President / Treasurer.
David Wooden was nominated for Secretary.

There was some discussion on what the club would like to accomplish. Some ideas included:
Events: Line Following competition, Demonstration at Woodfield Mall, or Museum of Science & Industry
Standardized Kit or Platform for members to build in order to gain experience.
Building period: A meeting devoted to members working on their robots.

Door Prize:
John Patrick contributed a stepper motor to give away as a door prize. We all stared at it for a moment, wondering what we could do with it. David Wooden finally claimed it, and asked the infamous specification questions.

More Show and Tell:
As the meeting adjourned, we all went out to John Patrick's car to see the rest of his robot gear. John had brought his battle robot, Endotherm, in a partially disassembled state. John showed us the battle scars it had incurred and the modifications he had made. John also showed one wheel pod from the new heavyweight robot he is creating.
