(...) Yep - I thought so...for things like cameras where these things are in common use, the need is only to know the range to the nearest object. I don't even know if the other things (multiple object detection and size/reflectance estimation) are (...) (23 years ago, 6-Feb-02, to lugnet.robotics)

(...) let (...) Thanks for that Steve. My circuit will be based on the latter of the two possibilities. It is based on a design by RA Penfold from Electronics and Beyond (Sept.2001) so I'm basically doing construction by numbers! However, the thesis (...) (23 years ago, 6-Feb-02, to lugnet.robotics)

Hi all, my name is Francis (from Spain). I've read Extreme MindStorms and I decided to put my hands on and build some new sensors. I began with the optointerrupter, but have a little trouble. When I connect the sensor to the RCX I can't get a stable (...) (23 years ago, 6-Feb-02, to lugnet.robotics)

(...) I guess the first question I'd ask is "What interface does the sensor present to the RCX?" I imagine there are two possibilities: It could be a raw interface that let you send an acoustic "PING" on command and read a voltage back telling you (...) (23 years ago, 6-Feb-02, to lugnet.robotics)

Now that my interest has been piqued by the multiplexer problem (and sensing problem in general), what would some of you hardened embedded/real-time system veterans recommend for reading on the subject. Two books that I've found at Amazon.com are (...) (23 years ago, 6-Feb-02, to lugnet.robotics.rcx.legos)

Hello all. This topic might be a bit old hat for some of you, but as a relative newbie to the world of Mindstorms, I'm posting in the appeal for any information on Ultrasonic Sensors. The brief of my honours project was to design and build one such (...) (23 years ago, 6-Feb-02, to lugnet.robotics)

Success! It works now, and gives 9.2 volts according to the RIS software. You were right, I did have it backwards. Thanks. (...) (23 years ago, 5-Feb-02, to lugnet.robotics.rcx)
