(A commercial post??****) Terry Fritz, a Colorado based engineer and creator of award winning robots, has designed the first new sensor to come on the market...
Interesting! Jim Ubersetzig gave a "Theremin" demonstration at one of the RSSC meetings a couple of years ago. And John Edwards - haven't you just bought one...
Hello Bruce, I just ordered one of the ThereminVision kits last night so it will probably be next week before I get it. I will let you know what I think of it...
Yes - I did demonstrate a Theremin musical instrument at an RSSC meeting a few years ago. It's 18 inch sensitivity made it suitable as a robot sensor. In fact...
Attached (and downloaded to the yahoogroups "files" area) is an updated copy of rules for the proposed hallway navigation contest. These rules include many of...
Alex - The updated draft looks good. Somewhat related question - when you read your sharp GP2D12 IR sensors, how many samples do you take? How often? Do you...
Meeting Minutes, San Diego Robotics Society, May 1st, 2004 Fun meeting. One new guy joined us, Rudy, who hopes to build a robotic vacuum cleaner. Alex B....
Thanks for putting down rules. You listed several question areas; my 2 cents are as follows: a) Obstacles: Let's go with boxes; I only mentioned trash cans...
MessageJim, Does the Theremin detect some things better than others? For example, people at 18 inches, but completely ignores walls? Or maybe it could detect...
Paul, Actually, I started out with all kinds of filtering. But, I ended up just sampling at 61 hz (my real time interrupt rate) and using the raw data. ...
Anything with a dielectric constant different than air ( air = 1.00 ) is detected by the theremin. Materials that contain a large percentage of air ( foam...
MessageHello Jim, I remember very well when you demonstrated your Theremin at the RSSC meeting. I for one was not laughing but inspired by your demonstration. ...
I am currently a student at UCSD. A group of us are looking to start a robotics club/team on campus, but aren't quite sure where to begin. We're looking into...
Thanks John When you have tested the sensor, please post your thoughts on its effectiveness. I kind of hope it will be useful for navigating through doorways, ...
Hello Puneet, I'm glad to see you and your friends are becoming interested in robotics, it will certainly provide you and your friends with many hours of fun...
ATMEL AVR? http://www.atmel.com/products/AVR/ Before I say anything else, I have to say I am a Pic Micro controller guy. It is what I was taught in school and...
Glad to read about the interest. The first question I would ask any college based robotics group is: Is there a embedded processor lab class on campus? If...
Thanks Bruce This is useful information. Interesting that paper and wood have the same dielectric constant. Jim Ubersetzig ... From: Bruce J. Weimer, MD...
Oh, just a reminder. I'm not planning on bringing in 30 copies of the proposed rules for everyone. If you are interested in discussing them, please download...
If you like BIG robots, read on. If that is not your slice of pie, pass this along and sorry for the bother. My name is Earle Bishop, and I am acting Project...
Hi all, I've updated the rules as we talked about and attached them to this email and placed them in the Files area. Practice and testing next month; and a...
Mark and Scott, I finally got around to playing with the Flexiforce sensor. (http://www.tekscan.com/flexiforce.html for you other guys) I just hooked it up...
A fellow at work is retiring. He want's to sell his oscilloscope ( he's cleaning out his garage ) He wants $ 50 -- including a complete set of manuals. Specs...
Yes, I use it on my robot; I did not write the complete code, but modified an existing version (with permission). What aspect are you interested in? Derek...
