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.

Yesterday I started working on a new robot base. The new locomotion did not fit on the "old" base, so I decided to start building a new one.

So far I am only barely satisfied. The thing looks like a wooden brick... with wheels. Anyway, I think it is a good step towards the third base, so I learned a lot from it -- right? Willem

Yesterday one of the two motors of my Tamyia Twin Gear Box died. When I opened the thing I found out that two of the four brushes where completely gone.

And that while the shaft sensor motor drive feedback program was getting on pretty well! Anyway, I posted the most recent code on my site today and.... started browsing for new locomotion!

Set up a small description of my robot project. Mainly consist of a reference to the website dedicated to it.
