New Members - we had three new attendees at the meeting: Nick Frank found out about the club through the battlebots web site. AJ Whitney and Dusty Whitney - found us through a search on the internet. RBNO - Clint gave a report on the last RBNO. PWM and motor control was covered in a round table format at Netplanner. He explained what the RBNO was for the new attendees. The next RBNO is in a couple of weeks, with the date on the internet web page. The upcoming topic has not been decided. Frank asked for ideas for future RBNO - one of them could be a review of other RBNOs. Monthly Contest - There have been 2 suggestions - a mini-sumo and a "maxi-sumo". The central Illinois robots club and the seattle robotics club. The Portland site is setting up a mini sumo kit. About half the attendees want to go with the sumo.

Chris Carter - Clint and he are working on the double sided tape version of linkx motion legs. They have made of aluminum - it is really large (picture made). Bob Baxter brought in the current copy of design news - a free design magazine Dale brought in his new robot using sonar as a sensor wanted to do wall following or something. He looked into sonar and bought a polaroid sonar module. He was not impressed because it had a range of 1.3 feet to 35 feet. It is a variable pulse width. Takes 80 milliseconds to get a result. One of the sensors he found has a far wider angle of use. It goes 6.5 inches to 5.5 feet. One transmitter and two receivers on each side uses a 16c73 PIC chip. (several pictures made) Sean Hussey - worked on a science research that follows people. Uses the bobot base and stamp 2 uses frequency sweep. He wrote a compiler that takes rsx code into an exe.
