Guibot's mothers shaver

Today I got a parcel with the post.

Wondering what it was, it was quite a surprice to find what I imidatly recognized as being Guibot's mothers shaver.

Guibots mothers shaver

Then I realized that about 1 1/2 years ago, I said that I would take it over if Guibot had problems coding..

wrt54g as robot brain

Andrey Mikhalchuk demonstrates how to hack a popular wifi router to have an rs232 interface (or two). The openwrt project allows us to actually use that powerful hack. Andrey did what few people did before: he added a micro servo controller and TING robot's done!

Arms for Edward

After lots of thinking about what my next robot should look like, I couldn't resist the temptation of trying to improve Edward. I never really made a good program for him and everybody who sees him ask me to switch him on and let him run around. When they do, i shrug and tell them "the batteries are dead" or "I'm still working on the programming".

The Making of Blaster Shark (Sumo)

Hello fellow robot builders,

Its been another while since my last post.  My building mojo has been renewed and I am starting a new sumobot.  The Vulcan Five is on hiatus until I can get the PCB replaced.  This time around I am building a minisumo which will compete in the upcoming Western Canadian Robot Games on May 15th.

Wheels - The Making of Blaster Shark (Sumo)

After the design of the body and motor mounts I can get an idea of what kind of wheels I need.  The things that are important to consider is the width and diameter.  Both are restricted by the dimensions of the the minisumo.  In my case, since the motor shaft is offset, I can go with a smaller diameter wheel and not worry about the bottom clearance of the robot.  But since the motors are somewhat long, I can't go with a really wide wheel.  With this in mind I figured that a wheel diameter of 40mm and a width of roughly 20mm would suffice.

PCB - The Making of Blaster Shark (Sumo)

The details of why I picked what parts I picked are covered in the Design blog.  What I am about to describe here is the tools and process I go through to design and etch my own PCB.
