Have done Computer Science/AI/Robotics at University of Amsterdam in 1992. Since June working on hobby robot project and describing the progress on my website since 1st august. Currently an administrator of the dutch robot club website (http://www.clubs.nl/community/default.asp?club=Robot). Member of the Yahoo virtual Clubs "TheRoboticsClub" and "ArtificialInteligenceGroup". Main interest in writing (AI) software -- but like the mixture of bare hardware, electronics components and software. No competitions yet, but planning for it. Maybe set up a competition in the Netherlands. Willem

Today I posted a fully documented SONAR LIBRARY for
the HandyBoard on my
website. It uses the Devantech SRF04 to measure distance.
The system is a-synchronious what makes it very little
overhead and easy to use on your own programs.
The library consists of the following files:
sonar.asm - the assembly driver (only needed for reference and change)
sonar.icb - the compiled assembly driver (goes in the IC\libs dir)
sonar.c - the IC library (goes in the IC\libs dir)
sonar.lis - the IC list file (goas in the IC\libs dir)
test_sonar.c - an IC test program
sonar_readme.txt - documentation
Included information on the sonar SRF04 routines I have implemented on my HandyBoard, on my website.
Pffuh. That has been a long time since I've been able to proceed on my project. Anyway. Finally got the nerve to order myself some distance measuring sensors: two Sharp GP2D02 (digital IR distance measures) and two SRF04 Ultrasonic range finders. Pretty cool stuff. I have placed the GP2D02's on the left and right of the vehicle to detect proximity to walls. The sonars I put in front. So I got some software to write. For the GP2D02's I got some routines of the net, the sonars I liked to do myself. And: it works. I wrote this little assembly program to send a pulse and count the time till its return. Amazing, huh? Now I can build myself a true wanderer that doesn't run into walls. I'll put the stuff on my website for you to see and comment.
Deeply shocked by the incidents we decided to shorten our holliday and go back a week earlyer then planned.
