*Robot Science & Technology* is a fairly new magazine, and I give it my high recommendation. Issues 2, 3, and 4 contain a series, "Popular Micromouse Algorithms", by Tak Auyeng, PhD. Lots of good info for anyone interested in the IEEE Micromouse (...) (26 years ago, 28-Jan-99, to lugnet.robotics.handyboard)

I assembled the expansion board and tested all I/O ports. Everything checks out fine. I have the 6500 sonar module with the flex cable. After loading 'sonar.c', I tried the 'sonar_display()' function. The transducer came to life with its 'clicking', (...) (26 years ago, 28-Jan-99, to lugnet.robotics.handyboard)

Thanks Fred and you too Ranjit, I have just now got my board to accept the expansion board files. I reloaded the expansion board zip files,installed in ic but still would not load. It did not give a error message for the expsens.c file but did for (...) (26 years ago, 28-Jan-99, to lugnet.robotics.handyboard)

(...) If your macro just calls the "move" routine it will make absolutely no difference because your are in effect typing in the above anyway. If your macro inserts the code for "move" inline rather than calling it it will be only very slightly (...) (26 years ago, 27-Jan-99, to lugnet.robotics.handyboard)

An article on the magazine, _Robot Science and Technology_ (relatively new publication), describes the micromouse competition and algorithms for maze solving. You can look up the HP somewhere and maybe get a back issue or something. I forgot which (...) (26 years ago, 27-Jan-99, to lugnet.robotics.handyboard)

I just saw the following: The artwork on the schematic sold by Douglas shows that RP1 is a 1Kx7 where as your schematic and parts list shows it to be a 1Kx4.

Hi all, Lately, there have been a few questions on wireless communication between a handyboard and a PC.

Fred, I thought I found a minor mistake in the parts list for the expansion board. But I now believe I didn't. The artwork on the schematic sold by Douglas shows that RP1 is a 1Kx7 where as your schematic and parts list shows it to be a 1Kx4. Since (...)
