| | Re:Solved?? rotation sensor problem
|

On Sep.10,I posted the message regarding rotation-sensor problem. I realized that the first threshold value '0x6fc0' in CURRENT_STATE is too small. Some sensors give raw values around 0x7000. #define CURRENT_STATE (raw<0x6fc0?STATE_0:...STATE_3))) (...) (26 years ago, 17-Oct-99, to lugnet.robotics.rcx.legos)

Can we make these things learn? I'm no expert on AI or nothing, but perhaps by making, for example, program 1 write program 2, write to program 3 etc, and use a some kind of a genetic algorithm to determine best output. Or would all this be (...) (26 years ago, 17-Oct-99, to lugnet.robotics)

| | Interfacing 2 Ultrasonic Modules onto one HB?
|

I am trying to interface two Polaroid 6500 ultrasonic ranging modules onto one HB to simplify my project. I know this has been done and it is probably very easy but I am not an electrical engineering expert and cannot figure it out. I have two (...)

Okay. Here is an update. I decided on a platform like the one on this page. Synchro Drive I have bought and finally recieved all the parts nessesary. It is going to use 2 rotation sensors to measure distance, and the angle of the wheels relative to (...) (26 years ago, 17-Oct-99, to lugnet.robotics)

Hello, I also would like to see a example of the sonars and expansion board hook-up. I also have a vector 2x compass module that was connected and working before the expansion board was added. Is it possible to connect the sonar and compass to the (...) (26 years ago, 17-Oct-99, to lugnet.robotics.handyboard)
