Total attendence: 26
The meeting commenced at 1pm by viewing the '99 Trinity Fire Fighting Robot Contest video that Jake brought in.
Next, we had introductions by Jake followed by the passing around of pretzels and the master e-mail list for updates and additions.
Jake brought out his stash of robot related literature including some copies of Circuit Cellar. He also hauled out his box of goodies which included wire, relays and power resistors. All were free for the taking.
Jake mentioned that the contest rules are on the web for Trinity 2000.
Next, Jake opened the floor to anyone wanting to show off their latest creations.
Bill R. was up first. While his laptop projected pictures from previous club meetings, Bill told us that Chris N. has been hard at work coming up with new and interesting contests for the CRS. Line following, maze running, and a Sumo competition are what's on tap for this year. Check out the details by clicking on the "Contest" menu selection on this site.
Walter was up next. He gave the group a review of his work on his 68HC11 C compiler (WCC11) written in Turbo Pascal. The new features that he has added since the last meeting included support for interrupts, characters, and procedures that can return a variable. At the end of the meeting, he and his laptop gave demos of the compiler in action, and he solicted input from the group for further enhancements. Walter also brought in his Fire Fighting robot from last year for show and tell.
Marc W. talked about a work project that involved precisely controlling the position of big R/C servos. The control box could handle up to 3 servos, and had a resolution of 128 positions. It was built around a 6803 microprocessor and a 8254 timer chip.
Next, Kevin demo'ed his Apple Disk Drive Servo robot. Hot melt glue was traded for electrical tape on this creation. It was radio controlled and despite a wheel that wouldn't stay on, it did work.
Chris Stratton, a member of the CRS in one of its previous iterations, came for a visit. Jake introduced him, and Chris told the group what he has been up to including his work in the E.E. program at MIT.
Scott B. brought in a new Leggo creation using the RCX "brick" that he hopes will be his answer to the Fire Fighting contest. The drive was 8 wheeled and could do perfect 90 degree turns - just right for running the Trinity maze.
Chris, a new member, offered to machine parts for CRS members. Thanks Chris!
Finally, Walter's sister demo'ed her walking Radio Shack Triceratops Dinosaur.
The meeting ajourned around 3:45pm.
